Hi all,

I've a simple question about ISA Server NICs configuration on three-homed
DMZ.
I understood I've to use public IP on DMZ segment, ok. But the nic which
connect my ISA Server machine to DMZ network, must have public IP too?

For example, take a look at this ISA Server's interface IP config...

Internet : 123.123.123.200
Subnet   : 255.255.255.248

Local    : 10.10.10.1
Subnet   : 255.255.255.0

DMZ      : 123.123.123.201
Subnet   : 255.255.255.248

So, I've to use 2 public IP address on my ISA Server machine?
Are there alternatives?

Thank you.
