MSN probelm in voice and vedio

Hi

While testing msn messenger with socks5, I too failed to initiate
voice chat. After some investigation, I got problem as below:

My msn messenger client is behind NAT and firewall. When we initiate
voice chat , we get invite message from internet in that message's
payload it sends its IP and port. In reply to that invite message we
send Invite Accept message. In that accept message we send our IP and
Port in payload but we have private IP to our PC system which should
not be in the payload.
This private IP is going as it is in the payload to external system
and that initiating connection on that private IP which will be
dropped in the internet. MSN messenger has to put NAT ip NAT port in
that payload as ICQ is doing.

Thanks

You need an ALG to do the translation from private to public IP.
