Hi guys! I attached my testbed! It's a small testbed, I don't need to look onto the internet. The wlan gets an address from 2001:738:2001:2082::/64 The
phone gets an address from 2001:738:2001:20a9::/64 The server in the
2001:738:2001:2081:/64 network.
I would like to make some SCTP failover measurement between the laptop and
SCTP server. I need a solution where the packets go via the proper
interfaces. (ipfw fwd doesn't work)
Static routes don't operate, because the packets always out on the default
gateway.
I work on my thesis and I haven't got too much time. Can you explain an
exact solution?

what I called routing a packet according to source, seems to be a well know (so to speak) thing: policy based routing: http://en.wikipedia.org/wiki/Policy-based_routing that, apart from ipfw fwd (for ipv4) is supported (more finely) by linux (with some bugs) and Cisco IOS (with more than some bugs I suppose...)
So, since you have a cisco somewhere, go and read:
http://www.cisco.com/en/US/docs/ios/12_0/qos/configuration/guide/qcpolicy.html

towards the end there is even a specific example for "ow to route traffic from different sources to different places (next hops)"

Thank you for making me look for this info, as I had already to patch macosx ipfw (the kernel really), to make fwd functional, but with this I will be able to do it in the cisco router, and leave the kernel alone...
