Hello,

We are deploying our centralized MMSC which will serve 2 countries (X & Z). A VPN exists between the GGSN(country X) and Wap Gateway(Country Z).

Country X already has a test MMSC of its own. They can send and receive MMS using that.

We note that while the MMS is initiated from country X, the firewall (PIX) in country Z can see incoming UDP traffic on udp port 1813 and sometimes TCP traffic on tcp port 8799.

The problem is that UDP traffic is basically the radius accounting request coming in from the GGSN (country X) and we can see a response going out from the WSB (Country Z), BUT THERE IS nothing after that.
Traces taken from ethreal(country X) state that they can see tcp traffic following after the response from WSB (Country Z) is received.
The two firewalls being used for VPN are PIX (Country Z) and NS500(Country X).

Please comment as we are stuck

Thanks
