Easy Question about default gateway/routing

Hello,

I have a Win2003 Server set up with IP address 192.168.0.122, and a DLink DI-604 Firewall/Router set up with address 192.168.0.1.  The router is currently set as the default gateway.  I have also installed Routing and Remote Access on the server with routing turned on.

The Win2003 book that I have explains setting up TCP/IP on the server, while the DLink documentation explains setting up the firewall/router, however, neither get into detail about installing the two together.

Basically, what I'm unsure of is if the server is set up to route, should I make the server the default gateway? Should I turn off (if possible) routing on the DLink? Is there a recommended (general) configuration for this situation?

thanks

you have to have 2 NIC in the server to be able to route and if so and if you want to go all yoru traffic behind the server trough the server then YES set the default gateway of the pc's in the LAN to the server. It has sense only if you are running some firewall on the server though. Otherwise the gateway is only the device which connects you to other networks.

So you are saying that without 2 NICs installed, using routing on the server doesn't really work?  I should turn off routing on the server then? I need remote access, so I can't uninstall Routing and Remote Access.

My question is - why do you need the server and the DLink both to be routers?

Secondarily, you need two IP addresses on the server for it to act as a router.  One way of doing this is to have two NICs installed, each with one IP.  However, you can accomplish this with one NIC by assigning the single NIC multiple IP addresses.  That's not recommended for a production environment, but if you're doing this as a lab, it'll do just fine.

Hi, Thanks for the responses.

It's not that I NEED both to be routers. Originally I had a crappy win98 file server on one old pc with a cheap linux firewall running on a separate old pc. Eventually the firewall pc died and I had problems setting it up on another old pc, so I replaced it with a relatively inexpensive DLink firewall/router.  Later I replaced the server.

At first I didn't have Routing and Remote Access installed, but then I was asked to try to set up VPN access. I had problems with that which haven't yet been resolved - I could get a Remote Desktop connection established through the firewall, but not a VPN. I  can, however, establish a VPN within the firewall, so my current opinion is that the problem is with the DLink. Anyway, the 'need' for a VPN has diminished as of late, so any settings for it can be undone for now.

At some point while playing around with the settings trying to get the VPN to work, routing got turned on. Later I tried to turn it off, but then everyone lost the network, so I quickly turned it back on and left it until now, when I have a lot more time to work on it. I'm working through the setup again hoping to iron out as many wrinkles as possible (there are a few other issues) and this question is one of the first...
