I have a home network connected to Verizon's FIOS service. Verizon's ActionTec router is connected to the ONT via coax to establish the MOCA network. My DD-WRT router's WAN port is connected to one of the ActionTec's LAN ports. The DD-WRT router is configured with a static IP address and assigned to the DMZ (this is done so I only have to configure port forwarding once).
My issue is that this does not allow computers connected to the DD-WRT to serve streaming audio/video to the MOCA network using Verizon's Media Manager. I know that Media Manager uses ports 18000, 18001, 5050, and 5060, but I don't know how to forward those ports so that they are only available to the ActionTec's network (i.e. the cable set-top boxes) and not the rest of the internet.
For ease of discussion, the IP addresses current being used internally are:
192.168.1.1 - ActionTec Router 192.168.1.2 - DD-WRT Router's WAN port (assigned to DMZ) 192.168.1.100-.103 - Set-Top Boxes (STBs) 192.168.0.1 - DD-WRT's LAN address 192.168.0.151 - Computer running Media Manager
