Subject:   Using freebsd as a router for small network

I have a small network, which up to now been served by a farallon ISDN
router.  The farallon box supports address translation, allowing several
machines to share a single ISP account.

I have a DSL line on order, and I'd like to use a free bsd box (boxes?) to
do the same function as the ISDN router.  As I understand it the DSL line
has a ethernet RJ-45, and the terminus is assigned a static IP address.
Obviously the freebsd boxes would need two Ethernet NIC's.

My questions regard configuration:

1) Natd of course looks like it is just the solution.

2) Do I need an additional firewall with natd?  I couldn't
     tell for sure from the man pages

3) Do I need two machines?  (or should I have 2 machines?)
       I'd like to run a proxy server (squid?)
       I'd like to run a Pop3 and SMTP server
       I'd like to run dhcp server
     If I run these on the natd macvhine, will things get confused?
     Are there security implications that wants me to run these on the
        intranet?

4) Are there other network services I want to configure.

5) Are there any pioneers out there that can warn me about
the pitfalls I'm likely to encounter?

Thank you in advance.

Forrest
