Your gatekeeper can reject calls from any unregistered endpoint by simply having AcceptUnregisteredCalls=0 under [RoutedMode] Section. This still will not protect your system since you can still have unregistered endpoints register to your gatekeeper if you don't have the following sections set. Example: ;############################################################ ;#Gatekeeper Authentication Section Defined. # ;############################################################ [Gatekeeper::Auth] AliasAuth=required;RRQ default=allow ;############################################################ ;#RRQ Authentication Section Defined. # ;############################################################ [RasSrv::RRQAuth] ENDPOINT1=sigip:xxx.xxx.xxx.xxx:1720 ENDPOINT2=sigip:xxx.xxx.xxx.xxx:1720 ENDPOINT3=sigip:xxx.xxx.xxx.xxx:1720 ENDPOINT4=sigip:xxx.xxx.xxx.xxx:1720 Adding these two sections will make sure that only Endpoints 1 thru 4 coming from the following IPs(xxx.xxx.xxx.xxx) can register to your gatekeeper and therefore call other register endpoints. I hope this helps.
