Hi all,

I am getting a lil lost and not sure where to find the issue.
Let me first describe the situation.

I have a small ipv4 subnet which is not having any firewalling so openly
connected to the internet.

If I give a tandberg 880 unit a public IP of this subnet I am able to call
and to be called. But of course I also receive lots of unwanted calls.

I want to use gnugk as a gatekeeper, but also to make sure not every
default call just comes in.

When I use gnugk and I have tried various configs I never am able to
receive a successfull call on the tandberg unit. There is a connection but
only the incoming video is shows on the tandberg screen, the tanberg video
does not come to the other endpoint.

I have gnugk installed on a raspberry with the following IP config:
eth0      inet addr:80.127.117.171  Bcast:80.127.117.175
 Mask:255.255.255.248
eth0.0   inet addr:192.168.2.1  Bcast:192.168.2.255  Mask:255.255.255.0


with the following routing table:
Kernel IP routing table
Destination     Gateway         Genmask         Flags Metric Ref    Use
Iface
default         a80-127-117-170 0.0.0.0         UG    202    0        0 eth0
80.127.117.168  *               255.255.255.248 U     202    0        0 eth0
192.168.2.0     *               255.255.255.0   U     0      0        0 eth0

The endpoint is having a static address on the 192.168.2.0 network.
for this network there is no specific router, I assume the raspberry with
gnugk will deal the the needfull things.

Can some of you advise me or share a config example?
I dont think the is a too unique situation.

Thanks

Maarten
