gnugk and router that supports h323

Hi,

I have a router that supports h.323.
It is Multitech 550vpn.

My network looks like this.

PPPoe 10.10.0.255/16 |-------------|
DSL-modem---------router----------------+ 10.10.0.1/16|
| |
| |
|-------+-----|
|
192.168.0.1/24
|
hub (internal network)

I setup my router to forward all packets to 10.10.0.1.
on 10.10.0.1 i have routing turned on and NAT.

Right now both router and DMZ 10.10.0.1 have no firewall rules.

On 10.10.0.1 I setup the gnugk with that configuration:

[Gatekeeper::Main]
Fourtytwo=42

[RoutedMode]
GKRouted=1
H245Routed=1
AcceptUnregisteredCalls=1
SupportNATedEndpoints=1
H245PortRange=30000-30020
Q931PortRange=40000-40020

[RasSrv::ARQFeatures]
CallUnregisteredEndpoints=1

[Proxy]
Enable=1
RTPPortRange=50000-50020
InternalNetwork=10.10.0.0/16,192.168.1.0/24
ProxyForNAT=1

[GkStatus::Auth]
rule=allow

[Gatekeeper::Auth]
default=allow

with this setup I am experiencing some problems.

People from outside can connect to the gatekeeper but whenever
they try to call someone in internal network the call fails.

I would like to know if my setup is correct.
Is forwarding ok on my router with h.323 support.

I tried to connect two endpoints without the gnugk and it worked.

Any ideas?
