This would not work in my config. The ISA server is connected to the
modem via Ethernet. Additionally, it is the DHCP server for the internal
workstations. It is a controlled DHCP environment due to outbound VPN
routing issues (need to use a different subnet internally than the
default 192.168.0 subnet to prevent routing confusion when VPN'd to a
remote server). I'm not aware of any way to change the default subnet
ICS gives out on the internal side. Would this work anyway with ISA
using RRAS? Would they not conflict each other? I honestly don't know
enough to know the answer.

I use a cable modem and have 30 devices connected via 3 switches.

 

Guys, its really simple, you do not need static IPs - share your
existing connection via ICS, DHCP, and a hub.

        Dan,

         

        Your cable modem provider should give you a static IP. However
it may cost you though the nose (like mine) and then they assign it by
mac address. I will be doing this same instance next week. So please
keep me updated.

        Dan,

        We have a cable modem and do NOT use DHCP. Why won't the cable
company give you an IP?

                I think. I'm changing from ISDN to a cable modem. The
cable co. says I must have my ISA server set for DHCP. Followed the
instructions in the Learning Zone for this type of setup. I tested it
against my ISDN router. Set it to do DHCP, gave the DHCP Client rule the
IP of the ISDN router as the remote computer. It won't get an IP from
it. I stopped the ISA Control, as suggested, still won't get the IP.

                Maybe it is the router, but I thought I would check
ahead if anyone has any thoughts on what else I might be missing.
