Ok this is my setup right now. I have SBS 2k3 Server with 2 NIC’s. One for the internet and one for the network (LAN). I have DHCP, NAT and my exchange server running on this machine. I been using the windows firewall in routing and remote access. I do not like it at all. I would like to switch to a hardware router. I have DSL and it is a static IP. I can set the router up for sure. But I want to disable the one nic card that the internet is plug into. Than have my hardware router  take over. Should I keep DHCP on my SBS 2k3 server going or should I just use the DHCP on the hardware router? Is my exchange configured by IP or will it work fine as long as if I open the ports for the router? Please advise

I would keep the DHCP service on your server, it will give you more scope options and helps with DNS dynamic updates. Make sure you disable DHCP on the router. You need to open/forward the appropriate ports on the router, depending on the services running on your SBS:
25 smtp
80 http
110 pop3
443 and 4125 remote web workplace
444 share point
3389 remote desktop
Then run the Configure E-mail and Internet Connection wizard by opening the server management console and going to the Internet and e-mail page and choosing connect to the Internet. It will walk you through the re-configuration and give you the option to configure with one network adapter. Then you can disable the other one manually.
Make sure you use the wizard though, as it will maintain all the interrelated services with SBS.

ALso you sound like you know alot about the sbs server. the reason I am switching to this hardware router is becasue the windows services and ports are not forwarding my ports. It will only work with windows ports
like I can set my regedit to chang RDP port and set port in sbs router to point to that pc and all is good. but anything othere than a windows service dosn't get routed like my telnet on my as400 or my camera system. do you think you might know the cause of this?

You should be able to configure RRAS to do the routing to the various ports, but I am not familiar with doing so. I am familiar enough though to say that I wouldn't bother. With custom services like that, personally I would much rather configure them with the router. SBS will work very well with either 1 or 2 NICs. Though I would never fault anyone for using 2, I always stick to one and avoid RRAS complications. By the way if you use RWW (Remote Web Workplace) which still works fine with 1 NIC you can RDP to any workstation or server without changing any ports in the registry.
I would stick to using RRAS for routing IP's if necessary, but a router is simpler and definitely when customizing port redirection.

You mention Win2K and SBS 2K3, is it the latter? Wizard exists on SBS only, and very important to use it.
