Hi guys,

i have a running IPv4 firewall filter for limiting tcp-traceroute. All works as desired:

term accept-traceroute-tcp {
     from {
         destination-prefix-list {
             router-v4-addr;
         }
         protocol tcp;
         ttl 1;
     }
     then {
         policer management-1m;
         count accept-traceroute-tcp;
         accept;
     }
}

Now i want to build the same filter for IPv6, but the statement "ttl" is not suported within family inet6 Does anybody knows the equivalent for IPv6.

Thanks in advance...
Regards,
Alex
