Two internal proxy interfaces? - 6.Sep.2007 6:39:33 PM

I having a mental issue here trying to wrap my head around a planned configuration, please throw me some ideas or at least a "don't try it, stupid"!

New planned config - ISA 2006 SE on Win2003StdSP2
Server has 4 nics:
1. External
2. DMZ Perimeter
3. Internal LAN
4. ?

Old config:
ISA2000 (#1) - all authenticated proxy traffic
ISA2000 (#2) - second server handles special-needs unauthenticated traffic.

On the new ISA2006 box can I use the fourth nic to handle unauthenticated traffic?  My Windows clients are all FW clients.  I have many macintoshes that are SecureNAT.  All systems are set up to proxy to the ISA.

Can I do this?:
nic1 - external, this is the only nic with a default gateway.
nic2 - dmz
nic3 - handles 99% proxy traffic, all must be authenticated (subnet 192.168.1.x)
nic4 - handles unathenticated proxy traffic (subnet 192.168.2.x) no clients on this subnet.  I set up a few routing rules on last internal router to pass special http to this nic.

Thanks, I hope I have provided enough information.
