Thanks for your tips guys! Diversion ad block does not seem to kick in when i connect to my router through wireguard contrary to openvpn. I’ll look into it when I get back home.

I don't use diversion, but the default DNS 1.1.1.1 :oops:should be changed manually in the WireGuard config on the iPhone.

Changing the DNS server on the client to the router address fixed the issue. Thanks Guys.
 
I am currently running wireguard in Ubuntu vm on my Mac as a test. I suppose after reading all messages here that I can re-use my current Ubuntu /etc/wireguard/w0.conf only rename it to w11.cong. I have a question about the DNS and policy routing for the clients. I use Unbound DNS on my AC86U as primary DNS - dnsmasq is disabled. Do I need to add DNS entry in the new wg11.conf under [Interface] section and point it to my router default IP?
As for the policy routing, I can modify current [Peer] AllowedIPs and change it to 192.168.50.2/27as an example.
Am I correct with these points?

Yes, expect it to work :). There are 2 parts to it:
1. Modify the sample /opt/etc/wireguard.d/wg11.conf with your information based on the provider's configuration - make sure to leave the commented lines as they are -.

2. At the WireGuard Manager menu prompt type vx - that will open /jffs/addons/wireguard/WireguardVPN.conf in the editor (nano).
Make your changes as appropriate on the wg11 line and use P for policy mode and use your provider's DNS or your Unbound internal IP DNS. Then on the rp11 line add
Code:
<Internal_Range>192.168.50.2/27>>VPN
Pres F3 to save, F2 to exit the editor. Then
Code:
E:Option ==> 4 wg11
to start the client peer. Once started you can check the status with
Code:
E:Option ==> 3
If you see lively figures as received / sent you're in.

Thanks for the information and details. Appreciate it.
 
Now that a bunch of people are onboard with this and using it, I'm curious if anyone has looked to see just how resource-intensive this is on their router.
Does it require the use of a swap on the entware drive to keep RAM on ac86u's happy? Or am I overthinking things?
I've only a 50/10 DSL service to my router - does a client connecting to wireguard server on my router have the potential to saturate the upload so that everything on my LAN is slowed down, or will my QoS (cake) keep everything humming along, both at home and remotely?
psychologically I'm ready to push the go-button on installing this, but I don't want any troubles from (at) home when I'm connected remotely
 
Or am I overthinking things?
I'm inclined to say yes, but I'll give you some pointers and let you come up with the final answer...

On the AX86U I'm working with I see little if any resource-intensiveness I could attribute to the WireGuard client and host. The swap file which is there because Skynet insists upon it has never been used while running WireGuard and/or any other workload, scripts etc. At all... There is though more memory and CPUs (double) on the AX86U than on AC86U and that makes a difference. Everything else, as in use cases, network configuration etc. is the other part of the difference.

As for the upload saturation potential - that's real, but in Cake and FlexQoS you have 2 solid options to mitigate that (not what goes through the tunnel though). I don't use QoS and don't have any resource intensive requirements while remote so I can't speak to that.

The WireGuard session manager (while still work in progress) is quite easy to install, configure and removes itself well. So, give it a try and let us know what the final answer is.

Right, double the processors and double the RAM in the AX over the AC 86...
Thank you. I'm leaning towards waiting for 386.2 with cake built-in, but I think I'll sleep on your recommendation and make a decision in the morning. Weekends are much easier to fool with these sorts of things without major disruptions to network users.

(If there's one good thing about Covid for me, it's how much I've learned about networking. It used to be a bit of black magic, now it's just magic, and I can wave my wand tentatively)

@Martineau: could you please publish a changelog of the dev branch. A lot has changed in v 4.01b2 ...

WireguardVPN.conf:
# RPDB Selection Routing rules same format as 'nvram get vpn_clientX_clientlist'
# <Desciption> Source IP / CIDR> [Target IP / CIDR]> WAN_or_VPN [...]
# WireGuard Session Manger v4.01
# Categories None =
# WAN KILL switch KILLSWITCH = N
# Statistics gathering STATS = Y

Where has the possibility of changing the IP addresses of the servers "gone?

Menu: 9 cl1_peer

# cl1_peer [Interface]
PrivateKey = xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
Address = .1 / 32 DNS = 9.9.9.9 1.1.1.2

I now have a lot of unanswered questions .....

What can I do?
It seems you need to set up DDNS, first off. I would guess that the script is looking for some indication that is not yet present because you may not have DDNS configured - this makes sense, because your end of the tunnel needs to be static, and DDNS makes it appear as such. If you don't do this, every time your ISP reassigns you an IP address, your WG server will "crash"

truthfully, though, you haven't given us enough details about your network setup to be able to help beyond this. sharing that will help people sort out why the install seems to have failed. in the meantime, you can get DDNS going for yourself
 
Will Diversion and Skynet still work when using WG?

***ERROR: WireGuard install FAILED!

What can I do?
It looks like the install failed due to some compatibility issues with wireguard-kernel and wireguard-tools.

Try removing the install (option 2), then run:
Code:
opkg remove wireguard-kernel wireguard-tools
Check for any errors generated by the wireguard kernel packages removal.

The lack of a DDNS should not be an issue. The script checks for the existence of the DDNS and if not defined it will use the WAN IP.

Re-install from the 'main' branch.

I have Diversion and Skynet working - I use the router's internal IP as DNS for the client peer configuration.

@Martineau: could you please publish a changelog of the dev branch. A lot has changed in v 4.01b2 ...

WireguardVPN.conf:
# RPDB Selection Routing rules same format as 'nvram get vpn_clientX_clientlist'
# <Desciption> Source IP / CIDR> [Target IP / CIDR]> WAN_or_VPN [...]
# WireGuard Session Manger v4.01
# Categories None =
# WAN KILL switch KILLSWITCH = N
# Statistics gathering STATS = Y

Where has the possibility of changing the IP addresses of the servers "gone?

Menu: 9 cl1_peer

# cl1_peer [Interface]
PrivateKey = xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
Address = .1 / 32 DNS = 9.9.9.9 1.1.1.2

I now have a lot of unanswered questions .....
Err,....it's an ALPHA development branch, so all sort of junk is there., so NO, there is no formal change log.

However, under wg_manager Alpha v4.0 the text config file '/WireguardVPN.conf' has been reduced to

Code:
# WireGuard Session Manager v4.01

# Categories
None=

# WAN KILL-Switch
KILLSWITCH=N

# Statistics Gathering
STATS=Y"
and is no longer used to hold the Peer definitions, however there is a migrate command used during the install to assist in converting from v3.0 and also import command if needed.

To create a new 'server' Peer you use the same peer command as used in v3.0
Code:
peer new [ip=xxx.xxx.xxx.1/24] [port=nnnnn] [auto={y|n}]]

e.g. a custom 'server' Peer...
Code:
[CODE]e  = Exit Script [?]

E:Option ==> peer new wg27 ip=1.2.3.4 port=54321

v4.0 has been rewritten to potentially allow monitoring of the connections

e.g. session duration and traffic per Peer

I have also decided to move the firewall rules into their own chain..

e.g.
Code:
Chain FORWARD (policy DROP 0 packets, 0 bytes)
num   pkts bytes target     prot opt in     out     source               destination       
1        0     0 ACCEPT     all  --  eth0   *       0.0.0.0/0            224.0.0.0/4       
2      200 31302 ACCEPT     all  --  *      *       0.0.0.0/0            0.0.0.0/0            state RELATED,ESTABLISHED
3     1182  105K WireGuard  all  --  *      *       0.0.0.0/0            0.0.0.0/0            /* WireGuard */
4        0     0 other2wan  all  --  !br0   eth0    0.0.0.0/0            0.0.0.0/0

NOTE: It is an ALPHA so things may not work or may/will change before the formal Beta.

Check /opt/etc/entware-release. The wireguard module requires Entware-aarch64.
This in this file:
Code:
release=entware
arch=arm
cpu=cortex-a9
cpu_subtype=unknown
float=soft
gcc=8.4.0
gcc_flags=-O2 -pipe -mtune=cortex-a9 -fno-caller-saves -mfloat-abi=soft
libc=glibc
libc_version=2.23
Is this good or bad?
How do I install Entware on the USB drive?

Edit:
I managed to install Entware-aarch64 on my USB drive.

Hello Monsieur @Martineau
Thank you very much for this useful script, it works fine but I have 2 problems.
If you have 2 dns in your client configuration, the qr code import failed on wireguard Android client => so I delete the second dns ip and voila it works with qr scan import.
My second problem, after a router reboot my client still connects but nothing works, no internet, no access to local computers in my lan ...
Wireguard server is up and runnning, even if I stop it and restart it, nothing works and I can't find any log to help ..?
I have Diversion lite and Skynet running on amtm Asuswrt-Merlin 384.17
It seems like my wireguard server configuration can't survive a reboot?

I managed to install wireguard manager. I want to use Cloudflare WARP (not WARP+) on my router.
I edited wg11.conf to this:
Code:
[Interface]
#DNS = 1.1.1.1
#Address = 172.16.0.2/32
PrivateKey = xxx

[Peer]
PublicKey = xxx
AllowedIPs = 0.0.0.0/0
Endpoint = engage.cloudflareclient.com:2408
PersistentKeepalive = 25
I also replaced the private key in the file wg11_private.key, the same with the public key in the file wg11_public.key (same keys as in wg11.conf)
Do I also need to edit WireguardVPN.conf besides "Y" at wg11? The rest of the wg11 line is cosmetic, correct?
I think, I do not need a server, so I put "N" at wg21.
I can ping 1.1.1.1 when wireguard vpn client wg11 is active, but I cannot resolve names.
At least I see some traffic: transfer: 17.20 KiB received, 48.46 KiB sent
To obtain the keys, I ran https://github.com/ViRb3/wgcf on my PC.
192.168.1.1. is my router
DNS Filter is set to "Router"
Under WAN, I've set 1.1.1.1 and 1.0.0.1 with DoT.

This is my WireguardVPN.conf
Code:
# NOTE: Auto=Y  Command 'wg_manager.sh start' will auto-start this Peer
#       Auto=P  Command 'wg_manager.sh start' will auto-start this Peer using it's Selective Routing RPDB Policy rules if defined e.g 'rp11'

wg_manager Beta Hotfix v3.05 available and Hotfix v1.13

EDIT:


Do you see the 'device' Peer connect to your 'server' Peer?


Assuming your 'server' Peer in listening on port 51820, run the following, then try to connect

Code:
conntrack -E --event-mask UPDATE -p udp -o timestamp | grep 51820
