Question : Routing Problem WatchGuard x750e Firewall

Hi Guys,
Basically our problem is we are required to link our domain/site to another domain/site, we have linked the two sites via a Wi-Fi bridge and the other company/IT Dept have setup the firewall rules on their router to allow connection between the two domains. We have tested this by means of not using our firewall as the routing device.

Today we came to setup our rule base on the firewall and we hit a bit of a brick wall really. The problem is we cannot get the test client to bypass through the firewall to connect to google using its IP just to test connectivity, as we have not yet setup the domain trusts/stub zones.

The Firewall throws up the following error; Deny 209.85.227.147 http/tcp 3980 80 1-Trusted 0-External Denied 48 127 (Unhandled Internal Packet-00)  proc_id="firewall" rc="101" tcp_info="offset 7 S 2771065904 win 65535.

I have probably over missed something on setting up the routing in the firewall but here is an otherview of the topology.

Int setup on firewall as 192.168.100.X, > Wi-Fi device 10.0.0.X > Wi-Fi device > 10.0.0.X > firewall at otherside 192.168.100.X

Can anyone advise on the correct routing that I need to input into our firewall in order for this to work successfully.

Any help will be greatly appreciated.

Many Thanks
