Hi All, Because Cisco GRE tunnel keepalive mechanism that must have public IP on both site. But I have one Router in NAT environment that it's ip address is private IP address and another outside Router is public IP address, so when I configure "keepalive" on tunnel interface, the tuneel interface would show "line protocol down" message directly....
If anyone have idea about this ? Thanks :) pigsign _______________________________________________ cisco-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/
