Don't have 2 PCI slots?

I used 1q-VLANs for two reasons:
1 - I can't fit 8 NICs in my machine, even using multiport devices.
2 - I'm not concerned with VLAN-hopping in my lab

As always, "better" is relative...

Did you set them up via VLAN due to having only 2 NICs or is that a
preferred way to do it?  I've several discussions with people on the
VLAN strategy, but haven't really come to a consensus as to which way
was the "better" method.

Hi Tom,

Nice stuff, bro.  Wanna see a screenshot of a "peripiheral network from
h377" - IOW, my lab ISA?  http://isatools.org/isasefw.scrn.PNG 

The 11 NICs in the systray represent two physical interfaces using
802.1q VLANS to serve 1 "external" network, 1 "Internal" and 8
"perimeter" nets (the remaining NIC is the single "internal" card that's
divvied up into the subnets).
4 benches, 8 racks and each one of them lives in a separate network, all
separated by ISA.

RRAS DHCP Relay (and a proper configuration) allows a single DHCP server
to handle all subnets.

As it turns out, this is getting to be a very popular deployment for ISA
- the "Branch offices that chain to a Home office array or server".
Maybe we should add this, too..?

Hey folks,

Let me know if this clear up any issues, or makes them more cloudy and
what doesn't make any sense. Final version, and complete series with
step by steps, will go on the ISAServer.org site later this month.

Configure ISA 2004 as a Network Services Segment Perimeter Firewall:

Thanks!
