VPN: Temporarily solve same subnet conflicts

I am using my Gl.Inet router while I am traveling and I connect to my home with VPN. Sometimes I have problem, when remote subnet is the same as my home subnet (192.168.1.x). Sure, I should change this to something not commonly used range, but I have many devices on my network and I don’t have time to change.

On my PC I am using this temporary solution:

sudo route add -host -interface ppp0

If I want to access home device at, it would be accessing trough ppp0 VPN interface.

It is possible to set static route like this on Glinet router?

You can add static routes on Luci.

Thank you, I tried to add here, but it’s not working. What I am doing wrong here? is my Wireguard VPN interface IP address, I want to do a static route trough this interface.

Anyone? :slightly_smiling_face:

I added more info here:

Manually specifying ip route trough cli works:

ip route add dev wg0

Any way to achieve this by GUI?

It would be also OK, if WG client/GUI interface would support PostUp/PostDown options:

PostUp = ip route add dev wg0; ip route add dev wg0; ip route add dev wg0; ip route add dev wg0;
PostDown = ip route del dev wg0; ip route del dev wg0; ip route del dev wg0;

So, any way to support PostUp/PostDown in Wireguard config? It’s part of Wireguard, but I don’t know if is implemented on Glinet firmware.

As this is standard we could add to the firmware. But the best way is to let the firmware do it if there is a good way.

In many cases wireguard will not have an UP/DOWN signal and will need to modify the source code or start a daemon

wg-quick is handling all this:


No need to modify any source or write a daemon.

At this moment how do you handle wg interface UP/DOWN commands? I think with wg-quick.
