Hi,
My setup is
Netmeeting-PC1 <--> Internet <--> GnuGK2.0.4/RHLinux9.0/IPTables
<-->NetMeetingPC2
GK is running in proxy mode.
Iam able to initiate calls 2 ways.
But one way communication is allowed.
PC1 able to hear voice .
PC2 is not ale to hear voice.
because,
My private IP masqueraded as public IP then reached PC1.
so, one way ok.
but PC1 send reply to my private IP (PC2).
so, datas are not able to reach My Linux Box.
but text chat working in both ways.
My firewall is allowed anything for voip.
My gatekeeper.ini
[Gatekeeper::Main]
Fourtytwo=42
[RoutedMode]
GKRouted=1
AcceptUnregisteredCalls=1
SupportNATedEndpoints=1
H245PortRange=30000-30010
Q931PortRange=30011-30020
[RasSrv::ARQFeatures]
CallUnregisteredEndpoints=1
[Proxy]
Enable=1
RTPPortRange=5000-5010
[GkStatus::Auth]
rule=allow
[Gatekeeper::Auth]
default=allow
any idea?
