First of all you should set the policy to DENY or REJECT and then permit only the protocols that you need. Then read something about the different ICMP types. For example: To ping a host on the outside you have to accept outgoing ICMP packets type 8: ipchains -A output -i $external interface -p icmp --icmp-type 8 -j ACCEPT To receive an answer to your echo request permit type 0 "echo reply": ipchains -A input -i $external interface -p icmp --icmp-type 0 -j ACCEPT Jens -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
