vot chto ya nashel:
11. MSN Messenger / Netmeeting do not work using voice and/or video.
This is because MSN uses port 5000 and your firewall does not allow a direct connection for this.
Solutions:
- Use Yahoo! Messenger instead - it doesn't have that problem
- Map the port inside you modem to a particular PC (See question 13)
- (not yet tested

disable the firewall in the modem. Caution: this is NOT safe!
