Yes, I did it. It's already enabled .. : -( !! I found another Microsoft article http://www.microsoft.com/technet/treeview/default.asp?url=/TechNet/prodt echnol/netmting/reskit/netmtg2/chpt4.asp, that talks about the ports that the netmeeting uses across a firewall. I did not know that the netmeeting needs the ports 389 and 522. I'm going to server publish these ports pointing to the Exchange and see what happens and I will tell you.

The meeting appears to start working, I can see and start the local video but the remote video do not starts. And when I open the Netmeeting and try to call to the phone number (in netmeeting.js and ISA gatekeeper) it ask me for the name of the meeting, but do not shows any meeting and still cannot connect if I specify the name manually.

I followed all existing articles (articles from isaserver.org, Microsoft articles, etc...) Inside the network everything works well, but if I try to start a conference from the internet it doesn't work. (it ask me for the name of the meeting, but I cannot see any meeting that I created). Thanks in advance, Marcio
