Windows XP ICS with SBS 4.5

If I have a good understanding of what you want to do, this should be your answer;

1. The LAN IP address of your new XP box (Must be a static address) must be excluded from your form your SBS box DHCP.
2. The IP address you assign to your XP boxwill become the default gateway address for your SBS box (Also must listed in the DHCP server on the SBS box)
3. DNS must be listed the same as #2 above
4. Your WAN address on the XP box must be static (A Real world IP) if I am not mistaken (Or can be DHCP from your ISP)

This is a best guess on how you have things wired. Please let me know how your net is wired, if yo have tried this & it does not work.

The SBS server has two network adapters

10.0.0.1 (Internal Network)
192.168.0.2 (Connected via reverse cable to the XP machine)

The XP Machine has two network adapters

192.168.0.1 (Connected via reverse cable to SBS)
x.x.x.x (BroadbandSatelite connection - Supplied by DHCP from ISP)

The default gateway on the SBS machine is set to 192.168.0.1 (The XP machine)

The following senario works:-

On the XP machine, enable ICS. This automatically sets the XP machine as a DHCP server, gives the network card the address of 192.168.0.1. (This causes the DHCP server on the SBS to Stop due to 2 DHCP servers on the network but thats not important at this stage). You can now ping addresses on the internet from the SBS server. Great! Works!

But
On the XP machine, If I disable ICS, set the Network adapter that is connected via reverse cable to 192.168.0.1
Enable IP Forwarding by setting HKEY_LOCAL_MACHINE\system\CurrentControlSet\Services\TCPIP\Parameters
IPEnableRouter Value Data: 1
add the route on the XP machine using route add 10.0.0.0 mask 255.255.255.0 192.168.0.2
Try and Ping from the SBS machine now and I get "Route timed Out"

I think there is something else that I should be doing, but I am not sure what.

Any ideas!

I will not get a chance to look at this problem again until next wednesday. Please be patient in getting a reply. But I will reply.

Now I have a better picture of what your trying to do. It sounds as though all your useing the XP box is for is a firewall & router (Not really what it's made for). If that's the case, you can save the XP lincense by useing something designed to do the job & for free!

Any/All of this info should have you up & running within a few hours of so. But, if you still want to use XP for the task, good luck!

For some reason when pasting links on this site, a sapce is thrown in. Remove the space in each lin & they will work. Best of luck!
