SBS GAteway

Hey all, i have recently installed a small buisness server
2003 server at work and i tried to set it up as a
firewall. i have tried everthign i can to try and get the
2nd network interface working, but it just wont, it says
it is connected and it gets an ip address fromt the
router, which has a built in dhcp server, but i cannot
acces the router, opinging or other wise, and i cannot
access the internet either,how ever it all works fine if i
plug the router into my primary network connection,

Currently this is my config:

Server Local area connection:
IP: 192.168.1.2
Subnet mask: 255.255.255.0
dns: 192.168.1.2

network connection:
ip 192.168.1.253
subnet mask: 255.255.255.2
dns: 192.168.1.2

i have tried changing the dns of the 2nd connection to my
routers ip address (192.168.1.1) and also putting them
both on a different subnet than the server network
connection, all to no avail, please help

thanks
shane

What version of SBS? Using ISA?

Honestly, with a single server shop, I'd ditch the idea of using your only
server/DC as a firewall/router. Get a decent firewall/gateway/router
appliance - they're pretty cheap. Just my unsolicited $.02

If you want to use any of the routing/firewall properties of sbs (or any
Windows server for that matter), the two NICs must be in different subnets.
The "private" side of your router must be in a different subnet from the
"public" side. If you are behind some other router, your "public" interface
may in fact have a private IP address.
