Actually, you'll find option 2 more functional.
The multi-NIC problem is only good if (ISA PCI Slots / VLANS) > 1.
Otherwise, you're screwed and only the single-master VLAN option is usable.
Generally speaking, if your switch can create VLANs, then routing between
them should be controllable as well.

Subject: [isalist] ISA and VLAN (partly OT)
http://www.ISAserver.org
Hey guys,
I'd appreciate if you could broaden my horizon on this topic.
Within a month or so I'll install ISA in an environment where multiple
VLANs are running (I still have to check out the hardware on site, I
think they use HP switches, but I'm not sure). Each of these VLANs need
internet access and firewall protection, but for security and legal
reasons, access or rather routing between the VLANs is not allowed.
As this is still in an early stage, I have not completed my homework
yet, but I would like to hear your comments. As far as I understand, I
will either have to install multiple NICs on the ISA box (one for each
VLAN), or I'll assign the ISA port on the switch to the VLANs (this
would enable routing between them, right?).
So which way do I go? Do you see any problems/issues with ISA here? Btw
they are currently using FW-1 to do the job.
Thanks for your help!
Mark
