Issues accessing Slingbox in different subnet.

I have a network with two separate subnets. One for all the AV equipment in the house and one for all the computers. The computer network is in the 192.168.1.0/24 subnet and the AV equipment is in the 192.168.2.0/24 subnet. The router is a "m0n0wall", with 3 interfaces. WAN, LAN and AV.

The issue that I am having is that I cannot access the Slingbox on the AV network from the LAN (computer) network. The m0n0wall has a firewall, however there are rules in place to allow all traffic of all types between the two subnets. I am able to ping across the subnets with no problem, however accessing resources such as the Slingbox from the LAN network does not work 100%. I am able to ping the Slingbox but unable to authenticate.

I suspect the issue is related to routing between subnets and possibly different types of packets used by the Slingbox.

Here's a diagram:

o WAN/ISP (Public IP Address)
|
o m0n0wall Router/Firewall
|
|\o LAN Subnet: Computers (192.168.1.0/24)
|
\o AV Subnet: AV Equipment and Slingbox (192.168.2.0/24)

The two subnets are equal peers and are not nested within another subnet. Both have direct access to the WAN/ISP.

Any assistance would be greatly appreciated.

Thank you for the info. I have been able to access network shares from the Music and DVD servers on the AV network from a PC on the LAN network. However, I'm pretty sure that it's got to do with broadcast packets or something of the sort. Unfortunately, the Slingbox website isn't very technical in it's support documents.

Also, I'm not sure how you'd route broadcast packets.... Any help would be greatly appreciated.
