I have successfully used NetMeeting between 2 users both behind a redhat firewall.. We had gotten video,voice and paint all working working fine using the H323 patch. The only thing we noticed as a glitch is that he could not connect to me unless I hosted a Meeting which only then he could connect to. Connecting to other non firewalled users was a piece of cake. It could not be just a simple listening host but had to be in a meeting which I found weird.. Maybe it was just my luck but at least I got them both working as we both were behind iptables machines.. Hope this boosts your confidence in iptables ;) Thanks, ____________________________________________ George Vieira Systems Manager georgev@xxxxxxxxxxxxxxxxxxxxxx Citadel Computer Systems Pty Ltd http://www.citadelcomputer.com.au -----Original Message----- From: hare ram [mailto:hareram@xxxxxxxxxx] Sent: Thursday, June 05, 2003 1:39 PM To: netfilter@xxxxxxxxxxxxxxx Subject: Re: MSN Voice chat with Iptables Hi all Does any one installed Upnp Successfully in REDHAT i been doing this practice more than 30 days now but no luck, any expert can guide me how can i process even i have posted in to linux-igd group, looks like the news group dead, no responce also for the same any help will be great hare
