[strongSwan-dev] MOBIKE

Hi all,

I'm trying some MOBIKE scenarios over UML (User Mode Linux) and it works
when I send some ICMP messages. However, I'd like to do some tests with
other traffic such as streaming or real time voice.

After establish a MOBIKE session, I've sent UDP traffic by means of IPERF
and TCP by copiying a directory using the SCP command. Traffic goes through
the tunnel but when I disable the current interface the traffic goes through
other available interface but not through the tunnel prevously established.
I've checked charon.log and it seems that MOBIKE works correctly.

This is the client's charon.log

Has anyone test MOBIKE with application layer traffic?

Best regards.
