Cisco ASR 1004 Issue with forwarding the packets.

Hi,
How can I allow the Router forward ICMP Unreachable Packets to the client when they find the application or network down.

g: --Internet---(Outside interface zone)----Router(ASR1004)----(inside interface zone)--Client.

Client browsing some data on the internet server and when the application doesnt responding the server will send the ICMP unreachable packet to the router. Now I want this router to send that ICMP unreachable packet to the clients. But the router is droppping or not forwarding the packets to the client on the inside interface.

I have allowed the permit icmp any any unreachable on both the inside and outside of the router but still its not forwarded

What commands do i need to configure on the router?

Any suggestion would be appriciated.

Thanks

Benjamin
