How to allow traffic to cross into shared internet connection

[sdoverkill]

I have an internal network (192.168.1.x) that has two things on it: a machine serving as a DLNA server and a Mac Mini (10.6.2) connected via wifi. The Mini is sharing its internet connection to a Samsung TV (sharing the connection creates a 2nd network; 192.168.2.x. Currently this is via DHCP but I am willing to go with a static IP if necessary). This allows my Samsung TV to access known internet services, but the TV doesn't apparently receive the DLNA broadcast messages from the DLNA server. I assume this is because the TV is on a separate subnet from the DLNA server.

How can I allow the TV to receive the broadcast messages from the DLNA server?

Thanks
