Linksys BEFSR41... Configuring as an internet gateway

Hi all,

I am looking for a little help with configuring my befsr41 router/switch to act as an internet gateway for my network.

I am currently running a handful of client (XP) machines connected to a server (win2000 server). I have DHCP running on the server assigning all IPs (192.168.1.100-149) to the clients therefore I have disabled DHCP on the router.

Even though I have configured my DHCP server to assign a gateway IP (192.168.1.1) to the clients, they refuse to access the web!?

I am no networking expert and I'm new to routers/routing...can anybody help?

I'm assuming that there's something missing from the routing table...

Currently the routing table has 3 entries:

Dest IP Subnet Gateway Hop

0.0.0.0 0.0.0.0 81.104.36.254 1
81.104.36.0 255.255.255.0 0.0.0.0 1
192.168.1.0 255.255.255.0 0.0.0.0 1

The IP 81.104.36.0 points to my Cable modem through which I connect to the web (it’s actual address is 81.104.36.197)

As I say, I am new to routers and so these tables don't really mean a great deal to me... can anybody help please?

Many thanks

Rob.

if your use your router as a switch or is connected on a switch then all your computer should have the routers ip as a gateway.

if you have the router connected to the 2000 server, and the clients connected to the server, then the client should have the servers ip as a gateway.

the IP 81.104.36.0 is only use from outside your lan, and should be shown as ip on your routers WAN menu

MrFujin: Many thanks for getting back to me.

What you have siad kinda makes sense to me and I think it all checks out ok.

I used to have 2 nics in my server : one for client connections and one for dedicated link to cable modem. It all worked fine. But I needed to install the router for Quality of Service reasons. The idea being that if the server was taken down for maintenance or fails, existing clients would still have web access through the router.

I just cannot get the router to pass client traffic out on the web for some reason...this makes me think it is a routing table problem, but I know nothing about routing tables.

I know the router works as I have tested it on a non-server/domain network.

Any ideas with this one???

If you have the router connected to one NIC on your server, make sure that you have enabled sharing on that connection and that all the clients have their default gateway set to the internal IP address of the other NIC (like MrFujin said).

This is just a guess, but see if you can access this site: http://66.102.9.104

I dont know if your routers is conneceted to a switch or the server, but for your purpose it is best to connect it to a switch.

have you tried to ping your router from the clients. (or just open the routers web manager in a browser)

Since you want your internet access to go directly to the router and not the server you need to configure your ip plan accordingly.

The IP 81.104.36.0 shouldn't show up in any table except the router. This would indicate a misconfiguration to me.

Before you decided to go direct to the router what was your ip plan/scope? My suggestion would be to input that scope into the router for the lan side access. This way you don't have to reconfigure ip on every workstation.

Router is plugged into the backbone switch. Everyone can get to the internet. Make sure to close off unused/hacker ports in the router.
