If your endpoints support RAS then you can set the following rule to allow only the endpoints that you want registered to the gatekeeper. [Gatekeeper::Auth] AliasAuth=required;RRQ default=allow [RasSrv::RRQAuth] H323ID=sigip:xxx.xxx.xxx.xxx Then based on the H323 Alias IDs they can call each other. But if your endpoints do not support RAS, then you will need to use the latest version 2.09 and 2.2 which supports UnregisterEndpoint Authentication through Radius. I do have a hack that I made for version 2.2b5 that allows one to specify an IP access list for unregister calls in the config file with out using radius. If you would like let me know.

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/ ------------------------------------------------------- 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/
