1:1 NAT means that for every IP you have inside the Cisco router, you need an associated public IP on the outside. You probably don't have that.

Try pinging the default route from the results of the "ip -4 route" command: # ip -4 route ... default via a.b.c.d dev ethX # ping -n a.b.c.d _______________________________________________ Discuss mailing list Discuss@blu.org http://lists.blu.org/mailman/listinfo/discuss
