OK, one lousy portscan did the trick, sorta. I now know that he's running xxx firewall and that it uses NAT (Network Address Translation) to do a single address assignment. According to the product's site:
Single address assignments allow a single official IP address to be used by a number of local hosts for out-bound only internet users. Single Address Assignments are usually allocated to internal ranges according to their priority levels.
But I still don't know how to redirect some of the incoming traffic to my comp. Any ideas?
Cheers,
