Hi Geoff,

>from server DHCP in the scope 10.0.0.100 to 10.0.0.255

Everything is on the same 10.0.0.x address. Neither ISA nor Basic Firewall
can do it's job.

You want it to look like this: (example). Note that the LAN and WAN are on
different subnets, so there is no traffic passed between them. This is where
ISA or Basic Firewall logically sits - between these subnets. You configure
ISA or Basic Firewall via CIECW, to filter (allow) only what you want to
allow.

Server NIC (Lan)
IP: 10.0.0.1
SN: 255.255.255.0
DNS: 10.0.0.1
DG: <empty>

DHCP is bound to the Lan nic, all client machines get addy's in the 10.0.0.x
range. This nic is connected to your switch/hub.

Server NIC (WAN)
IP: 192.168.1.2
SN: 255.255.255.0
DNS: 10.0.0.1
DG: 192.167.1.1

WAN nic is connected to your router.

Router (Internal)
IP: 192.168.1.1
SN: 255.255.255.0

Your router is set to forward ports you need open to your WAN nic.

The link I gave you says all. If you want a picture, go to
