Is there a way to tracert the ip ports, like I have a firewall that enables on the port 3400 and I'm outside of the network, if I tracert the firewall's ip it will show me the trace until the firelwall, but I won't be able to know if the firewall it forwarding to local ip ex: 192.168.0.0-254.

I don't know if I was clear enough so any questions let me know.

Thanks

mmm thats a good question :)

But tracert is basically just a lot of ping commands it sends three ping commands with a time to live of 1 hop so when the host unreachable comes back the next hop is shown in your command window, it then sends out three more with a time to live of two hops etc and keeps going till it gats there (when you get a Trace Complete statement)

So any tracert command will fail going therough a firewall that blocks ICMP

as to wheather you can tracert over a port I am unsure you can telnet over a port but tracert uses UDP traffic anyway so I dont think you can :(

No you can't as you can not ping or traceroute to an internal IP address behind a NAT device.  The firewall's public/routable IP address is as far as you will get.
