Bug Description
When fixing #513166, it was introduced that the "Local Port 0" option is always sent to vpnc. This however causes problems as some access point do not accept traffic other than from the default port 500.
There is no possibility in networkmanager to change this behaviour.
Since there seems to be a need for bothe, the default port 500 and random port selection as demanded in #513166, this should be made into a GUI option.

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.
