Linux multihome openvpn
Setup of OpenVpn on multihome box.
Problem is Openvpn answers udp packets back using default Gw, and selects different ip than incoming ip.
OpenVpn: Bind to all interfaces.
- Linux selects int/ip based on routing. Local gen packets select int before mangle can replace fwmark.
OpenVpn: Bind to lo:127.0.0.2, use nat to nat incoming on udp:1194 to 127.0.0.2.
Kernel bug ? Still selecting wrong source
OpenVpn: Multiple instances each bound to specific ext ip.
- WORKS! but need separate subnet for each instance, thus client ip changes when re-connects.
