Bug 8882 - With conntrack SNAT communication with PNF fails

Traffic from Non NAPT to PNF was failing, Since from non NAPT switch the
packet came through a tunnel port to NAPT Switch. There it was failing
since the vpn interface does not exist for tunnel port. Hence it fails
to identify the router id.

Now for the tunnel port the external ip associated with router used to
identify the vpnid.
