ICMP TTL=255
Hi,
I don't think that it's iptables fault, but I don't know where to ask else. ICMP Ping ignores the TTL value of net/ipv4/ip_default_ttl and use 255.
All other traffic use the net/ipv4/ip_default_ttl value.

if you mean with "ICMP Ping" your /bin/ping, it sets it's own TTL value. ping uses raw-sockets to send it's data, so i can set it's own values. What it likes. Btw: That's the reason why ping has the suid-bit set, only root is allowed to open raw-sockets.

Since they don't use raw-sockets.
