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. Michele Taverna - Italy
