Re: gk behind NAT

[Piyush Verma <piyush.pv@xxxxxxxxx>]

HI Simon,

Thanks a lot for suggestion.

I have forwarded port from 1 to 1730 means all ports between that will be forwarded to host.

I have fix IP I have tryied both way by entering fix ip or a domain name.

I have checked with nslookup that system is able to resolve piyush.ath.cx to that ip.

I think one possible problem could be that UDP is not forwarded to host. In NAT configuration there is no option for UDP/TCPIP so I assume it forward both by default. I need to figure out how to test UDP port forwarding.

Below is gatekeeper ini which is just nat.ini.

[Gatekeeper::Main]
Fortytwo=42
TimeToLive=600
;;ExternalIP=220.135.105.28
ExternalIP=piyush.ath.cx
ExternalIsDynamic=1

[RoutedMode]
GKRouted=1
H245Routed=0
CallSignalPort=1720
RemoveH245AddressOnTunneling=1
DropCallsByReleaseComplete=1
SupportNATedEndpoints=1
Q931PortRange=30000-30999
H245PortRange=31000-31999

[Proxy]
Enable=1
T120PortRange=50000-59999
RTPPortRange=50000-59999

[GkStatus::Auth]
rule=allow

[RasSrv::RRQFeatures]
SupportDynamicIP=1


Thanks & Regards

The ports to forward for call signalling is TCP 1720 not 1730.

Make sure your INI port ranges reflex the port forwards.

 

Port Forwards

UDP  1719                RAS

TCP  1720                Q931 (Incoming call)

TCP  30000 - 32000   H245 & Q931

UDP  50000 - 60000   RTP/RTSP

 

INI entries

[Gatekeeper::Main]

Fortytwo=42

ExternalIP=x.x.x.x

 

[RoutedMode]

CallSignalPort=1720

Q931PortRange=30000-30999

H245PortRange=31000-31999

 

[Proxy]

Enable=1

RTPPortRange=50000-59999

Subject: gk behind NAT

 

Dear All,

I have spent ed 1.5 day's to configure gnugk without success.

I have installed gnugk on a server behind NAT.

I have forwarded 1 to 1730 and 30000 to 60000 to the server.

I am able to connect ssh which ensure that port forwarding is working properly.


I am able to connect to GK from local ip like 192.168.1.35.

But I am unable to connect to same GK using public ip.


I have using NAT.ini and gatekeeper.ini  and updated public IP.


Any idea what step I am missing ?
