This sounds like a similar situation I ran into before. We had a trial period with a PolyCom unit over a year ago (we were running ISA2000 back then). It is a portable device that you were supposed to be able to plug into any network and it would just magically work with teleconferencing. Looking at the Tandberg website, the unit looks different, but basically the same type of concept. Well, I plugged it in, and of course it didn't work. So, I spent many hours creating the right ports definitions, trying to get the gatekeeper working, etc... No matter what I did, it would not connect through the ISA server. Sound familiar? Finally, it dawned on me that in order for the unit to work, it had to accept inbound requests. So, I published the unit as a "server", using the ports in the setup menus as a reference on what ports to redirect to that unit. Then, it finally started working! It's not a great solution, but it's much-much better than losing your ISA server. ________________________________ From: Barbara Causey [mailto:barbara@xxxxxxxxxxxxx] Sent: woensdag 1 juni 2005 21:52 To: [ISAserver.org Discussion List] Subject: [isalist] RE: Tandberg Video Conferencing thru ISA help http://www.ISAserver.org Hello All, After following the advice on this list and researching everything I could find about the Gatekeeper service I have been unable to make it work correctly so, I know it is not a popular subject, but does anyone have any suggestions as to the best hardware firewall I could get to replace ISA Server? I really don't want to leave ISA Server behind, but the Tandberg Video Conferencing MUST work! Thank you for your help, Barbara
