Bridging two nics on SBS 2003

I am installing SBS 2003. I have discovered that another firm that shares
the office space has their own router connected piggyback to the router of
the firm I am contracting with. The other firm has to use their router
because of HIPPA regulations. I have to call a centralized IT group to have
it configured.

The firm I'm contracting with doesn't know the username and password of
their very old Nortel router, so I'm replacing it with something new.

I have two nics on my server. Can I connect one router to one nic and the
other router to the other nic and create a bridge. Right now the other firm
has their router connected to one of the hub ports on my firm's router.

Or should I continue to keep the other firms router riding off of my firm's
router.

I guess this boils down to - what the heck do you use bridging for anyway?

Oh, noooo - don't muck around with this. Especially since you're using SBS -
don't make it mad, or it will hurt you.

microsoft.public.windows.server.sbs is the best place for any/all SBS
questions.

I wouldn't. In fact, if the other firm really has to abide by HIPAA
regulations, I'd bet they are not curently compliant.

On a DC/DNS server? Nothing, if you're smart. On an SBS box that isn't
running ISA, I don't even like two NICs at all. It's best to avoid that
configuration on a DC.

To separate the other company's network from yours, if you have to share the
broadband connection, would be something like this (you need at least two
public IPs)
