Hi there, I've a site where we have several H.323 devices all behind a NAT firewall. For this reason we use a GateKeeper to proxy the devices. Up to now we've been a bit lax and have been using an old version of gnugk 2.2 but are now trying to upgrade to 3.1. We've built and installed version 3.1 on a new machine running the latest version of Scientific Linux, and are using it with our old gnugk.ini file This has generally been successful in that the H.323 devices have all registered successfully and we are able to make outgoing calls both to E.164 numbers and IP addresses, all proxied through the GK. However where it falls down is we cannot accept calls. If someone tries to call us it fails with making the H.245 connection with the log message: Error: Establishing the H.245 channel failed, disconnecting When we do tests with a higher level of tracking we see 1) Location request received from Neighbour - followed by GK sending Location Confirm 2) We then receive a Set-up request from the calling address on say port 53188 i.e xx.xx.xx.xx:53188 3) This is forwarded to the called device on port 17:20 4) We then get an admission request from the called device from port 1719 which is confirm by GK 5) We then get a Set-up Alert message from the device which is then forwarded to the calling address xx.xx.xx.xx:53188 6) We then get a Set-up Connect message from the device and forward this to the calling address 7) The GK then starts a job for the H245 connector and reads from the calling address xx.xx.xx.xx:39884 and recieved a conference indication from the calling address port 1720 8) The GK then notes H45 connected from calling address:40302 on gatekeeper address:36289, which is immediately followed by the message "Invalid Address" and we have the Error establishing the H.245 channel. The gnugk.ini file is as follows [RasSrv::ARQFeatures] CallUnregisteredEndpoints=1 [RasSrv::LRQFeatures] AlwaysForwardLRQ=1 IncludeDestinationInfoInLCF=1 ForwardHopCount=9 CiscoGKCompatible=1 AcceptForwardedLRQ=1 ForwardResponse=1 [RasSrv::RewriteE164] 004401182= [RoutedMode] GKRouted=1 H245Routed=1 AcceptUnregisteredCalls=1 SupportNATedEndpoints=1 TranslateFacility=1 SendReleaseCompleteOnDRQ=1 [Proxy] Enable=1 ProxyForNAT=1 SearchBothSidesOnCLC=1 [RoutingPolicy] [NATedEndpoints] I know I've probably done something silly and obvious, but I cannot see what is missing Steve Cooper ------------------------------------------------------------------------------ LogMeIn Rescue: Anywhere, Anytime Remote support for IT.
