[gentoo-user] traceroute not working

[Tanstaafl]

Hi all,

Weird, I don't use it much, but needed to run a traceroute today, and it 
is failing with:

  # traceroute 192.168.1.4
traceroute to 192.168.1.4 (192.168.1.4), 30 hops max, 60 byte packets
send: Operation not permitted

I know the problem is in my firewall, because when I stop it, 
traceroutes work as expected.

I have allowed all ICMP in my firewall:

Chain INPUT (policy DROP)
target     prot opt source               destination
<snip>
ACCEPT     icmp --  anywhere             anywhere             icmp any
<snip>

Chain FORWARD (policy DROP)
target     prot opt source               destination
ACCEPT     icmp --  anywhere             anywhere             icmp any

Chain OUTPUT (policy DROP)
target     prot opt source               destination
<snip>
ACCEPT     icmp --  anywhere             anywhere             icmp any

Any ideas what I'm missing?

I can send all of my firewall rules privately if someone thinks I may 
have something that is dropping these packets before my ALLOW rule kicks 
in, but I'm fairly sure I have them right...

Thanks
