I would like to set up a one way trust to a domain on another network.
Is there a document out there to tell me what ports I have to have open
between the DC's or does anyone have that information at their fingertips?

There is a kb article from last month that defines ports but is not
specific to AD.

Thanks in advance...

Hello Robert,

I'd strongly suggest to use IPSec to secure your trust over the firewall. Then
you just need to open up ports 50,51 and 500. I guess for a trust you'll need
to enable RPC, which will make it tricky to configure and very unsecure since
you need to open up a broad range of ports for RPC.

Here's the information for IPSec over the firewall:
