1

I have te following setup in my GL-AXT1800;

  • vpn server (wireguard port 51821) used for remote connect lan/internet
  • vpn client (wireguard port 51820) used for vpn internet connection

When vpn client is on I cannot connect to WG server (no handshake).
If I switch of vpn client, connecting to WG server works fine.

Any suggestions how to set this up correctly so it will work.

kind regards, hrbrt

Hi,

  1. Make sure that the IP segment of the VPN client and the VPN server in AXT1800 are not the same

  2. The connected VPN client of AXT1800, is it a phone or a laptop? Please use Android or Windows WG APP to test it again.

  1. vpn client (nordvpn)

    Client Virtual IP (IPv4)

Hi,

We have found the cause of this issue. It is the router's DDNS service resolves the wrong IP, and it affected access to router VPN servers.

The issue version is AXT1800/AX1800 v4.7.0. Other models and firmware versions are not affected.

The following is workaround, please follow the steps to update gl_ddns:

The next firmware release will improve this issue.
