So you're saying your firewall blocks traffic coming from a random source port to port 500? It seems unlikely, but I guess some spectacularly bad implementations of state engines could do that.
There's a fix to that effect in 0.9.8.0, which I'll upload to raring shortly (providing a way to choose the source port). Following that point we may want to provide the updated package via a PPA.
