iptables can easily do it via mangle table. Is there any way using ipfw2

The size of the TTL field is fixed by the IP protocol to 1 byte; perhaps
you are looking for the IPFW transparent firewall option, which prevents
it from decrementing the TTL in order to make a "hidden" firewall...?

The other way round,want to lower the TTL as much as I want, as soon as
it passes my firewall.
