setting up a network bridge, a little help here

mbentley · 09-12-03, 11:20 AM

okay, first of all, i want to show how my network is setup so you can see how it is...

as you can see, i have part of a hard wired network on one side and then a wap to the the laptop, mbb2, and the workstation, mbb1. what i want to do is create a bridge on mbb1 that will basically allow mbb3 to connect to the main part of the network. i have tried, but then i have no access from mbb1 to the internet. can somebody give me a clue what in the heck i am doing wrong? what i eventually want to do is make with the network bridge and put the wireless card from mbb1 in that and make mbb1 and mbb2 wired from mbb3. (see picture below) i am definitely open to suggestions

You need to somehow set up mbb3 to work as a workgroup bridge. Meaning that your router will see the MAC of mbb3 but won't see mbb2 or mbb1. mbb3 will kind of act like another router all will still be on the same network. I'm not sure how exactly to do it with a pc, I have a very similar network setup but I use a linksys WET11 as my workgroup bridge.

by the way, does windows 2000 support network bridging?

*edit: sounds like i should have just bought another wap and done a wap to wap connection...*

Looking at your first diagram, you bridge wrong because you tried to make two different logical segments. If you are bridging, you are joining two physical segments into a single logical segment. So the boxes on both sides of the bridge would be in the same ip range, same gateways, etc.

What OS is on the bridge? I'd use Linux or OpenBSD for it, I think.

the first diagram isn't of a network bridge, that is just how it's set up right now. i am using xp pro to set it up. linux isn't a route that i will go for this. i set up the network bridge and give the bridge the ip of 192.168.1.2 , identical subnet (255.255.255.0) with a default gateway of 192.168.1.1 just like the rest of my computers are setup. the prefered dns server is also 192.168.1.1. once i have the bridge setup, and i lose all network connectivity to the other "main" side of the network.

it would be like this:

Hmmm well it logically looks fine, WinXP is probably doing something silly then.
