Yes it all plays fine like that.

No, I get nothing from that command.

I factory reset my router before beginning afresh just to eliminate any issues from old configs.

Good. That means iPlayer works via the UK tunnels when using IP address selective routing.

For the scripting method to work, you will need to enable custom domain names with dnsmasq. One method is to install AB-Solution. ABS will enable all of the dnsmasq features and necessary files for you.

Or, you can follow the wiki instructions here:
https://github.com/RMerl/asuswrt-merlin/wiki/Custom-domains-with-dnsmasq

Once dnsmasq is installed, we can collect the list of ip addresses used by iPlayer using the ipset method. Please perform the following:

Code: 
ipset create IPLAYER hash:net family inet hashsize 1024 maxelem 65536

nano /jffs/configs/dnsmasq.conf.add

and add this line:

Code: 
ipset=/bbc.co.uk/www.bbc.co.uk/IPLAYER

bounce dnsmasq:
Code: 
service restart_dnsmasq

Start watching iPlayer on your Applet TV and browse their website. Select as many options as you can to generate traffic. Also, issue the commands to perform more ip address generation
Code: 
nslookup bbc.co.uk 
nslookup www.bbc.co.uk

When done generating traffic and lookups:, review the list of IP addresses created for iPlayer traffic.
Code: 
ipset -L IPLAYER

I just tried putting in these 3 ranges into the policy rules GUI, which covers all those IPs:

52.85.83.0/24
77.72.112.0/19
212.58.224.0/19

But iPlayer fails to play. I guess I am jumping ahead of myself.

Edit: Got some more IPs but still no luck.

The challenge is identifying the IP addresses or domain names.

Thanks for trying thru the web gui though.

I was able to tunnel to UK and mined a larger list of ip addresses.

I will start a new post for next steps
 
Copy the list of IP addresses that were mined and copy them to /jffs/scripts/IPLAYER.
Add whatismyipaddress.com to the IPLAYER ipset in dnsmasq. e..g ipset=/whatismyipaddress.com/bbc.co.uk/www.bbc.co.uk/IPLAYER
Then issue service restart_dnsmasq. Do an nslookup on whatismyiaddress.com. Remove your laptop from the VPN gui and apply changes. Remove your laptop ip addresss from /jffs/scripts/OVPNC1 file. We want it to default to WAN. You can go to another geo ip tracking site to determine your WAN location. whatismyipaddress.com should report a location in UK.

Run this script:

Code: 
#!/bin/sh
logger -t "($(basename $0))" $$ Starting IPSET_VPN_Routing.sh..." $0${*:+ $*}."
# Uncomment the line below for debugging
set -xo
ipset create LAN_GW hash:net family inet hashsize 1024 maxelem 6553
ipset create OVPNC1 hash:net family inet hashsize 1024 maxelem 65536
ipset create IPLAYER hash:net family inet hashsize 1024 maxelem 65536

# extract LAN ip addresses
ipset add LAN_GW $(nvram get lan_ipaddr)

# extract OVPNC1 ip addresses
for ip in $(awk '{ print $1 }' /jffs/scripts/OVPNC1)
    do
        ipset add OVPNC1 $ip
    done

# extract IPLAYER ip addresses
for ip in $(awk '{ print $1 }' /jffs/scripts/IPLAYER)
    do
        ipset add IPLAYER $ip
    done

Sorry, I get lost when you say remove laptop from GUI and from OVPNC1 but then say whatismyipaddress should show UK (presumably from the laptop browser). It shows US and I can't see how it would show UK if I removed that laptop from the policy rules?

In any case, I have run that script, if by run you mean choose Execute from the right click menu in winSCP. The Apple TV is still able to browse iPlayer, but that is because the policy rule is still there for the apple TV to send all its traffic through the tunnel. (Removing that rule in the GUI for the appletv stops iPlayer again).

I meant delete the policy routing for your laptop in the OpenVPN web gui and delete it from /jffs/scripts/OVPNC1. Also, type: ipset del OVPNC1 xxx.xxx.xxx.xxx where x's are your IP address for the laptop. Bounce VPN Client. We want to test if you default to the WAN but the lookup to whatismyipaddress.com goes to UK.

Whatusmyipaddress reports WAN IP. As I said before there is no reason for it to report anything differently since your previous request was for me to remove all mention of my laptop IP from the script and from policy rules.

I asked a similar question on a different thread - posting it to a more relevant thread. Why am I receiving No chain/target/match by that name?

Since we listed the ip addresses of whatismyipaddress.com in the IPLAYER ipset , it was hoping the system would have routed the request via the VPN tunnel and reported the UK location and not the WAN. Even though your laptop is on the WAN. So, there is an issue with the script or other setting. Let me review my scripts and do some testing on my end.

OK, thanks.
It could also be that I am not rerunning the script properly as I do not know the proper commands to do that. I have just been executing from right click menu in winscp.
 
This was the first script I ran. It assigns clients to OVPNC1 or OVPNC2:

#               netsv4=`whob -h whois.radb.net -- '-i origin AS16625' | grep -Eo "([0-9.]+){4}/[0-9]+"`
#            Othwerwise, use the curl command. My brief testing has shown this to yield better results:
#               netsv4=`curl http://ipinfo.io/AS16625  2>/dev/null | grep -E "a href.*AS16625\/" | sed 's/^.*\">//; s/<.*//; /^\s*$/d'`;for net in $netsv4;do echo $net;done;unset netsv4
#
# Note 3: In the event one needs to use IPv6 in the future, the syntax is: ipset -N WHATISMYIP-v6 hash:net family ipv6
#
ipset create WAN0 list:set
ipset create WHATISMYIPADDRESS hash:net family inet hashsize 1024 maxelem 65536
ipset create WHATISMYIP hash:net family inet hashsize 1024 maxelem 65536

At first, it did not work. I had to bounce all of the VPN clients by selecting the Apply button and giving it a few seconds after the bounce was completed. whatismyipaddress.com resolved right away. It took three screen refreshes on beta.speedtest.net before it routed to UK tunnel.

I am able to watch iPlayer on my laptop while my geo location remains US! :D

ipset=/whatismyip.com/WHATISMYIP
ipset=/beta.speedtest.net/SPEEDTEST
ipset=/www.bbc.co.uk/www.bbc.co.uk/IPLAYER

I took some backups of the settings and files. I will leave my config as is for the time being. Breaking the scripts apart was helpful so I could focus getting one piece of functionality working and tested before adding more layers.

So I shoudl replace the IPLAYER script with the one you have here? What about changing the Client 3 to Client 1? Do I change anything else in the script?

Maybe it's easier for me to just fix what was wrong in the old script, but I do not know what you discovered.
 
You will have an WAN and OVPNC1 (UK) with fwmarks 0x7000 and 0x1000 respectively.

For your purposes, I would revise the first script to reference wan (0x7000) and opvnc1 (0x1000). Change the second script to route whatismyipaddress.com to opvnc1 (0x1000). In the third script, you can need to change it to route traffic to OVPNC1 or 0x1000 fwmark. You can leave the domain name look up sections or leave it as is for now. I had populated my ipset using the domain names earlier. So the contents of IPLAYER I posted earlier should already contain them. Or, remove these sections and see if it works for you:

Code: 
for domain_name in $(awk '{ print $1 }' /jffs/scripts/BBCdns)
    do
      echo "domain name:" $domain_name
      for ip in $(nslookup $DNS | awk '/^Name:/,0{if (/^Addr/)print $3}'); do
        echo "ip address is:" $ip
        ipset add IPLAYER $ip
    done
done

# Route BBC Player to VPN Client 3
for DNS in $(awk '{ print $1 }' /jffs/scripts/BBCdns)
    do
      iptables -t mangle -D PREROUTING -i br0 -d $DNS -j MARK --set-mark 0x3000
      iptables -t mangle -A PREROUTING -i br0 -d $DNS -j MARK --set-mark 0x3000

There is still fine tuning required. Running the routing for iPlayer broke my routing for SlingTV. I would need to do some more testing and refinement of the domain names and/or ipset list to resolve it. I may work on it as this has been interesting. I probably captured some roku domain names when I was trying to get it to work on Roku that need to be removed. The iPlayer channel on Roku is not supported for North American units so that is why it probably does not work for me. I had to load it as a private channel.

I like I said earlier, this is where the brunt of the work is and a lot of trial and error.

I would keep the scripts separate for now using my examples until you have it working for you. Then modify one script at a time and test before you update the next script. Once you have all the pieces working, you can combine or keep separate.

For example, in the first script, you want to put your laptop in the WAN and perhaps your tablet or phone in OVPNC1. Then test, if you go to whatismyipaddress.com with your laptop and it reports a WAN location and the table a UK location, then everything is working.

Then, on the second script, test to see if whatismyipaddress.com reports your geo location as UK. Go to another geo ip tracking site and see if your ip addresses reports in USA. Then that part is working. This is where I had to bounce the vpn clients.

And on the third one, see if you can watch videos on iPlayer without getting a geo location error message.

BTW, to run script from the command line if in the directory is:

./scriptname.sh

or

sh scriptname.sh

Once the list of domain names can be refined and tested, you can probably accomplish everything using this script. It will default all of your traffic to the WAN and send iPlayer traffic to VPN UK tunnel.

# extract OVPNC1 ip addresses

    do
        ipset add OVPNC1 $ip
    done

@Xentrk I'm trying the same scripts but receiving the No chain/target match by that name. What am I doing wrong?

Thanks

The copy and paste phantom does it everytime! check contents of your ipset lists e.g. ipset -L setname
And issue command to check fwmarks were created: ip rule

I always get that message the first time I run the script as the -D option deletes the chain. If I have not run the script yet, there is nothing for the command to remove, thus the error message. But, the -A opton will add it. If I run the script a second time, it finds matching chain with the iptables -D deletes the chain. Thus, no error message.

I was also able to configure pfSense to do the same thing this morning. Although the technique is different. No scripting is required. It was all done thru the web gui.

I first created a firewall alias called SlingTV for all of the SlingTV domain names. A copy and paste from the excel spreadsheet made it easy! The utility in pfSense converts the domain names to ip addresses when it is saved. I then created a firewall rule on the LAN interface to route any outbound traffic containing the firewall alias called SlingTV to use the LA VPN Server Gateway. If anyone wants to know how to do it on pfSense, let me know. I will post a how to in the pfsense forums in the next day or two.

Hi, I’m a complete noob here, but I started looking into policy base routing to route Sling TV traffic through a VPN. I’m interested in how you did this using pfSense. Any help would be greatly appreciated.

Okay I'm following post #548 instructions. I've got everything working but this step is giving me an error.

Code: 
iptables -A PREROUTING -t mangle -m set --match-set Hulu dst -j MARK --set-mark 0x7000/0x7000

I've copy/pasted it as well as typed it out, but constantly getting:
Code: 
admin@RT-AC68U:/tmp/home/root# iptables -A PREROUTING -t mangle -m set --match-set Hulu dst -j MARK --set-mark 0x7000/0x7000
iptables: No chain/target/match by that name.

I have AC68U with 380.68 FW and iptables v1.4.14.

Any help will be appreciated it. Thanks.
