hi, i just hung up with linksys tech. they tried to help me connect to msn messenger voice conversation from behind the router. they made me go to the router configuration page and open multiple ports (i will not post them here until someone asks for them). that didn't help. i was still unable to connect to voice conversation. the tech, then, asked me to connect the laptop directly to the cable mode. i did that and the voice conversation worked flawlessly. he finally told me he was going to transfer me to a senior tech, but i got disconnected. i called back with case number, but the second tech told me msn voice conversation uses dynamic port or ip that's why even if i open the correct port for now it will change later. that's why there is no way to connect to msn messenger voice conv. from behind a router that uses NAT firewall!!!! ... now how true is that? can anyone help me fix this problem? it will save me a lot of money on making overseas calls to family!!!
