OpenVPN on Multiwan: Outgoing where Incoming

[Guest]

Hi,

I am trying to achieve the following:
* MultiWan with Fallback (runs)
* OpenVPN on both external IPs (runs)

Problem: OpenVPN on Uplink2 sends answer packages via the default GW (Uplink1), but should send it via Uplink2.

So there a two possbile options I see:
1. configure OpenVPN to distinguish on which Uplink the Client connected (is that even possible) and set the gw for that Connection to that Uplink (using )
or
2. Create a policy routing entry alike "split access": lartc dort org/howto/lartc.rpdb.multiple-links.html
.. then again, I have no clue how to enter such kind of policy routing entries via webinterface :/

any hints?
