Re: Would using iptables limit my number of possible hops?

There is a way to limit the number of hops with iptables, but it is

firewall during your trace. And use tcptracert -n DEST PORT rather
than tracepath / traceroute.

Hi Buck; thanks for your reply.

Oooh, I hadn't heard of tcptracert before. Nice new tools! Thanks for
the link (for the innocent bystanders in this thread, it's in Ubuntu,
and therefore presumably Debian: sudo apt-get install tcptraceroute).

However, the good news ends there:

$ tcptraceroute -n 213.171.216.230 80
Selected device eth0, address 192.168.11.10, port 45415 for outgoing
packets
Tracing the path to 213.171.216.230 on TCP port 80 (www), 30 hops max

The odd thing is that everything else seems to be working just fine.
It's just so odd and inexplicable.
