[Tuexen Michael] Hmm, sounds like the client and servers run
on the same host. This 'feature' was never fully supported and will
be dropped with the next release. We only support then having multiple
sctp processes running with disjoint sets of IP-addresses. This needs
the forwarding table to set up in tune with the processes.

[Tuexen Michael] We definitly have to add something!

[Tuexen Michael] How to run the server:
./echo_server -s 192.168.1.1 -V
For the client use
./echo_client -s 192.168.1.2 -d 192.168.1.1 -n 1 -V

This should generate traffic and lots of output.
