Hi,
   I've just setup my first Cisco router. It's an 837 ADSL router. I've got it up and running ok but I want to stop it replying to ICMP requests although I want to allow ICMP requests out. It's the first time I've touched a Cisco router although I'm aware that to set advanced settings you have to telnet into the router and use commands. I have managed to get into the privileged command sets but don't know the exact command I need to deny ICMP coming in. Any help would be greatly appreciated.

Thanks.

Hi lee
See what you need to do is to apply an access list which will deny all your icmp traffic.
give this command in the config mode.you can enter the config mode by typing 'config ter' at the priviledged mode.
once you are in config mode give this command
access-list 101 deny icmp any any echo.
see if that works
regards
