Internet pass through problems with Server 2003

We are having intermitent problems with our internet connection going through
the server. Our setup is: cable modem -> router/firewall -> server ->
internal network
From all stations on the internal network(10.0.0.X) we lose internet
connection, but keep our email connection (ie using outlook express, we can
send and receive email to (E-Mail Removed)). From the server (192.168.0.1),
we continue to have internet connection, so I believe we lose the connection
within the server. Occasionally, the problem goes away and internet
connection is reestablished to the internal network. Other times, I have to
reboot the server which solves the problem. I have checked the system and
security olgs and do not see any problems. DHCP and Routing/Remote access
all seems normal. Any thoughts or ideas? Thanks in advance.

assuming you have two NICs in the server, it could be RRAS and routing table
issue.
