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.
