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.

YES Both the interface are assigned two public interface from different the exit interface a.b.c.d and inside int is assigned e.f.g.h to which a host is connected i am able to ping from the host up till a.b.c.d but not to ping public dns there is no access list and and is not nated

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 ?
