Hi Laura
I had the same problem a while ago. I had an UDP OpenVPN server on my
firewall, and 3 routes to the server. No matter which incoming route you
used, it only ever replied on the default route.
The only ways to fix this are either switching to TCP, or moving your Open
VPN to a host behind the firewall and DNAT'ing your OpenVPN traffic to that
host.
