Vpnc pluggin needs "force-natt" option.



Hello all!

I have a situation where vpnc is failing due to an incorrect setting in
the NetworkManager vpnc plugin.  The situation is a condition where a
firewall or other non-NAT device is interfering with protocol 50 (esp)
and we need NAT-T even though we are not behind a NAT.  As it so
happens, vpnc does support this.  It's "NAT Traversal mode force-natt".
In those environments, cli invocation of vpnc works like a charm.  But
there appears to be no way for the NetworkManager vpnc plugin to
configure and use this.  The force-natt option is most likely to work in
the widest variety of environments at the cost of a slight overhead (UDP
encapsulation).  OpenSWAN, StrongSWAN, Racoon, and vpnc all support
this.  Just need the plugin adapted to support it as  well.  Any chance
of getting that added to that plugin?

Regards,
Mike
