Greetings, I am trying to "hide" my firewall from showing up on traceroutes, but want my network to be pingable. So, I've forwarded icmp type 8 through the firewall to a host that will do the echo replying. As you can see below, when I omit the "1" from the command, I get a message to specify a value. But when I add "1" as the value, I get a "No chain/target/match by that name" error... Any help would be appreciated. -Bill [root@BULLDOG /]# uname -r 2.4.20-6 [root@BULLDOG /]# rpm -q iptables iptables-1.2.7a-2 [root@BULLDOG /]# [root@BULLDOG /]# iptables -t mangle -L -n -v Chain PREROUTING (policy ACCEPT 56522 packets, 32M bytes) pkts bytes target prot opt in out source destination Chain INPUT (policy ACCEPT 14410 packets, 919K bytes) pkts bytes target prot opt in out source destination Chain FORWARD (policy ACCEPT 42112 packets, 31M bytes) pkts bytes target prot opt in out source destination Chain OUTPUT (policy ACCEPT 13576 packets, 1318K bytes) pkts bytes target prot opt in out source destination Chain POSTROUTING (policy ACCEPT 55687 packets, 32M bytes) pkts bytes target prot opt in out source destination [root@BULLDOG /]# [root@BULLDOG /]# [root@BULLDOG /]# [root@BULLDOG /]# iptables -t mangle -A PREROUTING -j TTL --ttl-inc iptables v1.2.7a: TTL: You must specify a value Try `iptables -h' or 'iptables --help' for more information.
