Hello Martineau,

I have tried a few times to make it work, but unfortunately it does not. The guest networks does not to talk to each other. I started with the simplest possible solution and did not provide any lanip. Could that be a problem?
I have performed a factory reset (with and without loading back saved router settings).

So to recap.

You have mapped wl0.1 through VPN Client 1, and wl1.1 through VPN Client 2 but you want clients to communicate?

Hopefully you have tested - assuming you have added the specific client IPs (or subnet for ALL clients) to the appropriate Selective Routing GUI:

1. When a client connects to 2.4Ghz Guest #1 it can access the Internet via VPN Client 1?
2. When a client connects to 5Ghz Guest #1 it can access the Internet via VPN Client 2?​

(The above basic functionality has worked since v1.03b)

However, only later versions include the 'lanip=' and 'join=' options.
e.g.
Code: 
./WiFiVPN.sh wl0.1 wl1.1 join
So depending on the use of the two options, additional rules will be added.
Please provide the output from:
Code: 
iptables --line -t filter -nvL MyVLANs
 
Hi again,

I am sorry if I mess anything up here in this thread as I am not interested, yet, to add any VPNs. In the future, very likely but at least not now. (But I do have a long wish list :))

I issued these commands which I believe should bypass VPN:
Code: 
./wifivpn.sh wl0.1 novpn autodnsmasq
./wifivpn.sh wl1.1 novpn autodnsmasq
./wifivpn.sh wl0.1 wl1.1 join

Hopefully you have tested - assuming you have added the specific client IPs (or subnet for ALL clients) to the appropriate Selective Routing GUI:

2. When a client connects to 5Ghz Guest #1 it can access the Internet via VPN Client 2?​

I have tested that both bands successfully can reach the internet.

Please provide the output from:
Code: 
iptables --line -t filter -nvL MyVLANs
Click to expand...

Here it is:
Code: 
 iptables --line -t filter -nvL MyVLANs
Chain MyVLANs (1 references)
num   pkts bytes target     prot opt in     out     source               destination

The problems with the above is that it looks good to me ;-) but I am merely a novice when it comes to routing.

Thanks, but I don't understand why your status command shows references to the two VPNs :confused:, rather than this:

Also if you have issued the 'join' then two rules should have been inserted at the top of the MyVLANs chain (also the two explicit DROP br1 to br0 and br2 to br0 seem to be missing?:confused:)

Can you try inserting the rules manually
e.g.
Code: 
iptables -I MyVLANs -i br1 -o br2 -m state --state NEW,ESTABLISHED -m comment --comment "Join wl0.1 to wl1.1" -j ACCEPT

iptables -I MyVLANs -i br2 -o br1 -m state --state NEW,ESTABLISHED -m comment --comment "Join wl1.1 to wl0.1" -j ACCEPT

Thank you very much for helping me (and hopefully a bunch of people struggling with the same challenges)!
There was a problem with the two supplied lines:
Code: 
nimda@RT-AC68U-DC28:/jffs/scripts# iptables -I MyVLANs -i br2 -o br1 -m state --state NEW,ESTABLISHED -m comment --comment "Join wl1.1 to wl0.1" -j ACCEPT
iptables: No chain/target/match by that name.

Can you try explicitly loading the iptables 'comment' module
Code: 
modprobe xt_comment.ko

modprobe -D xt_comment.ko
then try to add the rules again.
 
Hi Martineau

I have enabled Guest 1 & Guest 2 Wifi and have Client 1& 2 VPNs but am getting a syntax error

Three possibilities:

Confirm the script actually exists with the expected name/executable attributes:
Code: 
ls  -lah /jffs/scripts
or
Code: 
sh -v /jffs/scripts/WiFiVPN.sh -h
1. First line is not
Code: 
#!/bin/sh/
Try
Code: 
sh /jffs/scripts/WiFiVPN.sh -h
2. Script is not Unix format or the Encoding is invalid.
However, if you used the router's nano editor then this shouldn't be the cause?
Try
Code: 
dos2unix /jffs/scripts/WiFiVPN.sh
3. You have inadvertently introduced a typo in the code when you copied it?
Try downloading or copy'n'paste the script again but use say WinSCP's editor (or notepad++)
 
Hi Martineau
So I thought I would start from scratch

Still not working with - line 4: syntax error: unexpected ")" :(

1st Attempt I saved as 'WiFiVPN' in nano via Notepad++ (Copy/Paste into Nano):

Code: 
/tmp/home/root# cd /jffs/scripts
/jffs/scripts# ls  -lah /jffs/scripts
drwxr-xr-x    2 admin    root           0 Jan 22 17:44 .

-rw-rw-rw-    1 admin    root       44.5K Jan 22 17:44 WiFiVPN

/jffs/scripts# sh /jffs/scripts/WiFiVPN -h
/jffs/scripts/WiFiVPN: line 4: syntax error: unexpected ")"
/jffs/scripts#

2nd Attempt assuming typo and that maybe I should name it as 'WiFiVPN.sh' - I re downloaded wifivpn.sh_v1.0x_beta.sh and deleted 'WiFiVPN' :

Code: 
/jffs/scripts# rm WiFiVPN
/jffs/scripts#  ls  -lah /jffs/scripts
drwxr-xr-x    2 admin    root           0 Jan 22 17:57 .

Dunno what's happening. I will try a factory reset and start all over? I suppose that this has nothing to do with v.1.03b :oops:
Also does it make a difference activating the OpenVPN client before installing your script?

No.....although the script will ensure that the VPN is actually configured and will automativally start the VPN if it is DOWN. (NOTE: This behaviour may not be what you desire.)

NO! :eek:.....I severely doubt a reset to factory default would fix a script execution error, so such drastic action would be a complete waste of time. o_O

When I first posted scripts on Pastebin, despite the various options provided by the Pastebin GUI, users apparently had difficulty downloading the scripts in the correct format.

Consequently I did write a simple script (before dos2unix was formally added to the firmware) for anyone that regularly needs to retrieve any of my scripts:

As shown above there is no syntax error in the original file download, but I suggest you try and cut'n'paste the following into the command prompt:
Code: 
curl -kL https://pastebin.com/raw.php?i=94Gf5hru | tr -d '\r' > /jffs/scripts/junk.sh

chmod +x /jffs/scripts/junk.sh

/jffs/scripts/junk.sh
to see if this method works.
 
Thanks for the hand holding:)

I usually simply press on download on pastebin to get my scripts
upload_2019-1-23_6-47-31.png


But will try the pastebin.sh - presume I have to install it as usual through nano and execute. Off to work now but will try it later:D
 
So formatted JFFS then ran the foll at Putty command prompt:
Code: 
curl -kL https://pastebin.com/raw.php?i=94Gf5hru | tr -d '\r' > /jffs/scripts/junk.sh

chmod +x /jffs/scripts/junk.sh

VPN works kind of but same client VPN2 on both wl1.1 & wl1.2 eth1 &2 and my LAN:confused:. Is that because I started at the wrong end and should go the https://www.snbforums.com/threads/2...-ssid-how-to-route-traffic.41222/#post-349086 route first before even getting to setting up things??

I use NordVPN so i do not have any other UDP port options I think and am loathe to use IKEv2, OpenVPN TCP as you may have suggested elsewhere- are there any other workarounds?

Thanks!:D

Well as stated previously, whilst drastic, this destructive action should ensure that there are no filesystem errors, but I wouldn't normally expect this to be performed every time you encounter a script/creation execution issue. :rolleyes:

So to recap, your original post was as a result of you being unable to correctly copy'n'paste the WiFiVPN.sh script from the Pasetbin source into the nano editor, as the manual cURL command line method to retrieve/create a working script was sucessful?

You can have as many interfaces mapped to a single VPN Client, but you must have enabled Selective Routing in the VPN Client GUI and entered the appropriate Policy rules for the devices/subnets etc.

If NordVPN only offer UDP:1194/TCP:443 then if you try to run concurrent NordVPN VPN Clients, to the same socket, then you will most likely experience VPN routing issues. However, if you only ever have one VPN ACTIVE at a time, then you may ignore the 'warning message' (WiFiVPN.sh is simply trying to be helpful, as it cannot prevent you from potentially shooting yourself in the foot!). NOTE: v1.09 of WiFiVPN.sh reworked the check so if you need it then let me know.

If NordVPN's TCP:443 is not acceptable (unacceptable performance/throughput degradation?) then I'm afraid without another VPN provider, you will most likely be restricted to one ACTIVE VPN Client at a time.
 
Thank you so much Martineau - I will have to do so more Noob homework!:eek:

I believe if unique subnets are allocated in the routing table then each tunnel would have their own interface and gateway (making it look as different devices are connecting to the different tunnels ) is that right? (NordVPN allows 6 concurrent connections)

No.

The router's VPN Client connection to NordVPN counts as one device, and all LAN/VLANs/Subnet devices routed via the VPN Client are MASQUERADE'd as a single connection.

aha! Cheers!
 
I am sorry I did not properly read this thread as a lot of my questions were already covered. I appreciate your patience :oops:
 
EDIT : Okay, I was testing the VPN SSID from an android phone that was ignoring the IP attribution rules (!!). It was actually (partially) working all along.
The DNS problem remains though.

Hi Martineau, hi guys,

I'm new to this forum and to the "router scripting" world. I ended up here after buying a AC87u router and earching how to get segmented WiFi network.
First, thank you for your script Martineau !

I've been reading the thread for a few hours and trying various things, but no luck 'til now... I must be doing silly things as every step of the way is not working as it should ^^.

Infos about my setup :
- The router is behing my ISP box
- The WAN IP of the router is 192.168.1.21
- Router's LAN IP is 192.168.2.1, subnet is 255.255.255.0, range is 192.168.2.2 to .254
- 4 SSIDs are enabled : the 2 main ones (2.4Ghz and 5Ghz : ASRT and ASRT_5G) + 2 Guests (ASRT_VPN and ASRT_VPN_5G)

Here is what I did :
1) Activated 2.4Ghz Guest SSID n°1 and 5Ghz Guest SSID n°1 (with no lan access)
2) Set up my VPN Client n°1 (Provider : TigerVPN), with exclusive DNS configuration. I tested it by enabling it on "all" trafic temporarly : it works (dnsleaktest shows the VPN IP and the VPN DNS).
Then I switched to Policy Rules (Strict) and added a Dummy VPN Rule.

Note that Create NAT on tunnel is enabled : I read that it could cause problems on another post... But I tried without it and it still fails.
3) Downloaded and ran WiFiVPN.sh (1.03b)

First surprise : the output of ./wifivpn.sh status is quite odd. Even though 2.4Ghz, 5Ghz and two guests are enabled, it shows the following :
Code: 
(wifivpn.sh): 6910 v1.03b (Public Beta) © 2016-2017 Martineau, WiFi VPN status request.....[status]

        WiFi->VPN Configuration Status for interfaces:

        wl0.1   ASRT_VPN         2.4GHz Guest 1
        -----   (ASUS_Guest2)    2.4GHz Guest 2  ** Disabled **
        -----   (ASUS_Guest3)    2.4GHz Guest 3  ** Disabled **
        -----   (ASRT_VPN_5G)    5GHz   Guest 1  ** Disabled **
        -----   (ASUS_5G_Guest2) 5GHz   Guest 2  ** Disabled **
        -----   (ASUS_5G_Guest3) 5GHz   Guest 3  ** Disabled **
        eth1    ASRT             2.4GHz Network
        -----   (ASRT_5G)        5GHz   Network  ** Disabled **

As if most networks where **Disabled** ??
I ignored that and tried to run the script anyway with ./wifivpn.sh wl0.1 1 : logically, it failed since I did not set any bridge before, and offered to use autodnsmasq, which I did.

/etc/dnsmasq.conf (generated by autodnsmasq) :
Code: 
...
# Bridge br1 uses DHCP pool 192.168.101.2 - 192.168.101.20
interface=br1
dhcp-range=br1,192.168.101.2,192.168.101.20,255.255.255.0,14400s
dhcp-option=br1,3,192.168.101.1
dhcp-option=br1,6,192.168.101.1
dhcp-option=br1,252,"\n"

Then the probems really begin :
1) When I connect to ASRT_VPN, my IP is not in the specified range : it should be 192.168.101.x but instead, it is 192.168.2.x, which corresponds to br0 range. Do not know why...
EDIT : okay, if I connect with my laptop, the IP is in the right range. If I connect from my phone (which I was doing from the begining), it is not. Android is totally ignoring the router's IP attribution... It works from my laptop. I have internet access through my VPN. But the DNS problem remains.

brctl show :
Code: 
bridge name     bridge id               STP enabled     interfaces
br0             8000.382c4aab5de0       yes             vlan1
                                                        eth1
                                                        vlan4000
br1             8000.382c4aab5de1       no              wl0.1

2) WiFiVPN.sh fails at retrieving VPN's DNS. When I run ./wifivpn.sh wl0.1 1 it says :
Code: 
(wifivpn.sh): 11049 v1.03b (Public Beta) © 2016-2017 Martineau, Guest WiFi VPN Bridge request.....[wl0.1 1]

        (wifivpn.sh): 11049 WiFi (wl0.1) 2.4GHz Guest 1 ASRT_VPN (192.168.101.0/24) routed through tunnel VPN Client 1 (TigerVPN) using WAN DNS () via bridge:br1
And when running ./wifivpn.sh status after creating the bridge it says :
Code: 
wl0.1   ASRT_VPN         2.4GHz Guest 1  (192.168.101.0/24) routed through tunnel VPN Client 1 (TigerVPN) is MISSING a valid DNS entry in '-t nat DNSVPN1' via bridge:br1

I know that last error has been mentionned before, but the offered solutions don't seem to fix it for me.
EDIT : that problem remains. Even now that I'm connected to ASRT_VPN and that it is working, dnsleaktest show my VPN IP but all DNS are my ISP's and not my VPN provider's.

I must be doing something really stupid somewhere, but I can't figure out what... Could you help me ?
Thanks a lot.
