By default Linux uses the IP of the interface used to route a package. The might often complicated the routing tables required at client networks.

A solution to fix this issue is to use Linux source/policy routing. For example, for node with IP 192.168.10.1 and VPN server IP 172.29.148.1, route to subnet 192.168.9.0/24 out 172.29.148.1 via 172.29.148.2 with src (source) IP 192.168.10.1:


sudo ip route add to 192.168.9.0/24 src 192.168.10.1 via 172.29.148.2
