The best way is with 2 ethernet interfaces. One for (semi) exclusive
use by the firewall domain (either running in Dom0 or in a DomU) and the
2nd ethernet interface used by all of the DomUs as the "internal" side
and connected to your LAN segment. The firewall domain then does the
NAT duties to move traffic between the two ethernet interfaces.
Tom Eastep over at Shorewall does this one his systems:

- Firewall is in a DomU
http://www.shorewall.net/XenMyWay-Routed.html
- Firewall is in the Dom0
(Just toss a cheap linux-compatible NIC in a PCI slot for the external
interface if needed.)
