I have a test lab set up with SBS2003 and a Linksys Wireless Router that is connected to a cable modem.
What I would like to do is configure SBS to be a router between a local subnet, where the clients are, and the Linksys/Cable Modem. The server has two NICS labelled WAN and LAN respectively. The LAN subnet is 10.0.0.0/8, and the WAN subnet is 192.168.19.32/27. The Linksys' IP is 192.168.19.61 and that side of the SBS is 192.168.19.41. Locally, the SBS uses the IP address, 10.255.255.254. A Win XP client is addressed 10.255.255.253. The XP client cannot get out to the web, nor can it ping the Linksys router's interface.
RRAS is enabled but I cannot create a default route to the Linksys router. RRAS gives an error telling me the subnet is wrong for the default gateway. I am not sure how to set up default gateways on multi-homed servers. The server's DNS is set to forward all queries to my ISP's DNS servers, and to only listen on the local interface (10.255.255.254). Iwas under the impression that Windows will automatically route between subnets for locally connected interfaces. Am I wrong?
