It's using IP protocol 47, not a TCP or UDP port. So, you will need to write the appropriate rule to allow it to pass. If you're using NAT, you'd also need to configure forwarding for that as well. --Justin _______________________________________________ discuss mailing list discuss@openvswitch.org http://openvswitch.org/mailman/listinfo/discuss
