My administrator said, all ports was forward to my internal IP.
My network adapter has only one IP like 192.168.0.x with DHCP. This IP is only in LAN. In the WAN a have external IP like 62.1.1.x.
All ports from external IP (62.1.1.x) is forwarding to my internal interface (192.168.0.x).
From WAN (from other computer) when I using ssh, www, webmin - it's working.
When I try to use aMule (mldonkay too) display me users, and number of files but don't have connect.
Have you eny expirience with routers or configure aMule from NAT with external IP ?
