i have a 2 GL-SFT1200 (Wireguard Server / Wireguard Client). It works perfectly so far. I can connect to a plc or pc, if the gateway is set to the Wireguard Client IP Address. So now i have a situation, where the Gateway is used for different communication stuff, and i need a solution, there i can access the Wireguard client network without that gateway is configured.
I think i need something like IP routing, but the examples i found do not fit, to this router. For Example i found a solution to configure a wg0.conf file, that does not exists.
Also i found this (Search google for wireguard-how-to-access-a-peers-local-network)
PostUp = iptables -A FORWARD -i wg0 -j ACCEPT; iptables -t nat -A POSTROUTING -o wlan0 -j MASQUERADE
PostDown = iptables -D FORWARD -i wg0 -j ACCEPT; iptables -t nat -D POSTROUTING -o wlan0 -j MASQUERADE
But not sure in which file, it should go.
I am almost there, but i do not find final step.
Thank you for your help.
