So the machine is behind a DSL router on a private IP so that it can not receive inbound requests. I want to know:
Is there anyway to setup the router NAT (i highly doubt it supports one to one port mapping) without disturbing other users on the same router.
I have another machine on internet which has public IP on it without any firewall. Can i use this machine as a relay server so that to initiate the connection, the XP machine send an outbound request and this relay server makes my connection through and then i can access my machine on pvt ip without any problem.
