Prakash, it is probably your NAT and/or access list, can you post configuration, strip out publig IP info.. can you discribe your topology physical connections.

hello,

i suppose you use ip addresses from public ip address space, and because of this you don't need NAT.


can you do one traceroute from internet to you assigned ip addresses ?
