Routing data Between 2 Subnets

[asdf]

Have two subnets which were configured by my predecessor.
Computers on one subnet can see communicate with all the
devices on another. However recently we got a new device (slingbox)
which converts cable signal into tcp/ip format. Devices on one network
can communicate with the device just fine. I can connect to
it and change settings. However pc's on the other subnetwork
can see device but can't conenct to it. I get error message saying
that i need to check my firewall and router settings. Now assuming that
this message is correct what settings would i need to change on either of
the routers on each subnet. I guess i need to open up some port or create a
rule to route the devices communications to both networks. I just don't know
enoough about this to be completely sure.

PS: I can telnet to the device from either subnetwork. but all i get is some
jumbled characters. Pinging works from both subnets as well.

And we'd need to know quite a bit more to be able to give yo an answer.
Check your router/firewall configs. The problem appears to be betwen the
networks. My first guess is that the new device doesn't know it's way to the
other network, perhaps because it is it's own default gateway (or points to
a gateway on the cable side). You'd need a static route to the other network
via the local (intranet) router interface.
