Hello Guys,
Iam using flint router as a vpn server (wiregard) and a beryl ax as client everything is working fine except when i try to connect to avanti secure client through this configuration. do you have any idea if i have to change some settings ?
iam using DDNS for my configuration
thank you guys
You will need to play around with the MTU, I guess.
Any proposition for the values I can start to test with ?
Set your computer or Avanti MTU lower to 1280.
Hi thanks for your answer but I do not have access to avanti configuration can I change it on the wireguard server or client ?
Can you change mtu on your computer?
I can change it but I think it’s not the issue I’ve seen that ivani recommends to set mtu to 1500 I’ve change it on the gl server and client the problem maybe related to the fact that iam using WireGuard to connect with ivanti who use ssl maybe someone had the same issue
Pls change as I said, change to 1280, not 1500.
Done change to 1280 but still same issue
Solution found it was the dns I just let the dns on the beryl blank and now its working thanks guys 
I recently ran into issues with my GL.iNet router while using WireGuard alongside another VPN (Ivanti) on my work PC. I kept experiencing intermittent disconnects and slow connections. After some troubleshooting, I found that lowering the MTU (Maximum Transmission Unit) on the WireGuard interface to 1280 resolved my connection problems!
