I'm sure this is a simple question, but searching through the archives I couldn't find anything. I have several h.323 video endpoints, on several different IP Addresses (non-consecutive). I want them to be able to call each other (or external people's endpoints), but not accept calls from anyone else. I found GNUGk and am setting it up. My thinking is to only accept registrations from certain IP addresses, and have the gatekeeper only allow calls from registered endpoints. I assume that I'd need GKRouted=1 so that it could block calls, and I've set the GKStatus:Auth to allow those endpoints to connect (which I don't think is needed, actually, except for whichever computer will use the Java-based admin app). What do I need to do next? I looked at the different authentication methods (including RadAliasAuth), but I don't see anything that matches what I'm trying to do. Any help greatly appreciated. ------------------------------------------------------- SF.Net email is sponsored by Shop4tech.com-Lowest price on Blank Media 100pk Sonic DVD-R 4x for only $29 -100pk Sonic DVD+R for only $33 Save 50% off Retail on Ink & Toner - Free Shipping and Free Gift. http://www.shop4tech.com/z/Inkjet_Cartridges/9_108_r285 _______________________________________________________ List: Openh323gk-users@xxxxxxxxxxxxxxxxxxxxx Archive: http://sourceforge.net/mailarchive/forum.php?forum_id?49 Homepage: http://www.gnugk.org/
