Routing issue when both VPN client and VPN server is ON

On AT1800 at home, I have WireGuard server turned on, with subnet
On ATX1800 in office, I have WireGuard client connecting to home server, with IP
It works for a period of time.

I have just turned on WireGuard client on AT1800 at home.
Now I cannot connect to when WG-client is on.
Turning off WG-client brings back network.
I have tried excluding in “based on target IP” or “customized rules” but did not work.

How to configure so I can access ?

By the way, I have tried putting these into the WireGuard connection configuration, and the UI fails to load.

AllowedIPs =,,,,,,,,,,,,,,,,,,,,,,,

Connection is still fine. But the routing is not correctly setup accordingly.

I’ve also experience this issue with my AXT-1800. WG clients connected to the AXT WG server will lose internet connection if the VPN Client is turned on. I was hoping to have both WG server and OPVN server turned on as backup in case WG connection doesn’t work when traveling, but this may prove to a challenge.

Do you have only one router named AXT1800, and connecting to it with a phone or computer?
And there WG and OVPN servers are running, without any problem, but
problematic only when WG / OVPN client is turned on?

I have added this in OpenWRT → Routing
Interface: wgserver
Route tye: unicast
Gateway: (ignore)

It is shown on routing table:

root@GL-AX1800:~# route -n
Kernel IP routing table
Destination     Gateway         Genmask         Flags Metric Ref    Use Iface       U     0      0        0 wgclient         UG    0      0        0 eth0   U     0      0        0 wgserver       U     0      0        0 wgclient UGH   0      0        0 eth0   U     0      0        0 br-guest   U     0      0        0 br-lan   U     0      0        0 eth0

But I cannot connect to

Pls wait for 4.1.1 firmware, which fixed VPN client and server running at the same time, aka vpn cascading.
