I can't match packets on the TTLI want to mark the packets that, after being routed, have a TTL less than 10 with the following command:iptables -v --table mangle -A POSTROUTING -o h_0_0-eth0 -m ttl --ttl-lt 10 -j MARK --set-mark 10But I keep getting the same error:MARK  all opt -- in * out h_0_0-eth0  0.0.0.0/0  -> 0.0.0.0/0   TTL match TTL < 10 MARK set 0xaiptables: No chain/target/match by that name.I am using iptables v1.4.21. I assume that it is not a problem of loaded modules, since the verbose output recognizes the TTL match.Does anyone have an idea of what could be the problem?
Mark packets with iptables based on TTL and length
