i have 3 comps.....middle one has 2 network cards and it is connected by each one to another computer.It looks like this:


comp1 ------------- comp2 --------------- comp3
192.168.0.1 192.168.0.2 192.168.0.3 192.168.0.4
255.255.255.0 255.255.255.0 255.255.255.0

Comp2 can see both comps.....but comp1 and comp3 cant ping or see each other.......All 3 comps have win98se installed.......
It seems that comp2 does not route net traffic from 192.168.0.2 to 192.168.0.3 ??????
So Please help?????
Do i need wingate or some routing software?
Server based games like UT work well as long as the comp2 is the server
Thanx in advance!!!!

How are they networked and what operating systems are they running? Also, it will be difficult to answer this post without more info on the network configurations. Larry

I recommend a hub/switch.
I'm not sure if there is specific software to enable you to do it but likely it would cost more than a hub. Or if you're really anti-hub put 2 NICs in each machine haha.

Or: Get some 10Base2 cards with BNC connectors...

It takes a big man to cry, but it takes a bigger man to laugh at that man.

Do yourself a favor and forget 10BASE2 (thinwire coax Ethernets). That recommendation comes from someone who has built and supported many of them and a theoretical believer in the virtue of coax as a superior transmission medium as compared to twisted-pair transmission lines. In the real world, however, if you don't know how to build a coax network and don’t know exactly what to build it with, it is going to have many more problems than twisted-pair network, and you won't save any noticeable money using coax over twisted pair. A 100BASE-TX network is in fact more reliable and faster than 10BASE2 network. See http://duxcw.com/faq/network/thinwire.htm for more on this subject. Larry

If you dont want to use a HUB or SWITCH, conect them in Triangle.

or as to say: in each copmuter two nics and connect each one to the two opposite ones.
Be aware of MUCH traffic, beceause you are theoreticaly creating a closed loop with it!!

I might add that I have tried the two network card thing and tried to get a Windows bridge working between them, and got the same results: two networks that could not “talk” to each other and one PC that could talk to each separately. That was done with a thinwire Ethernet at our second location. (At our first location we had a much larger staff, two businesses, and a building with two floors wired with thinwire Ethernet and a Cabletron multiport repeater--about $1,500 back then). Although the routing table thing is supposed to be possible, I gave-up and bought a hub and 10BASE-T network adapters. The hub was then replaced with a switch and the adapters were upgraded to 100BASE-TX. It, in turn, was replaced by a combination broadband router/Ethernet switch. What is to be learned from this evolutionary process? If you going to build a small LAN and have or are planning a shared cable of DSL Internet connection, start with a router/switch (http://duxcw.com/faq/ics/diffrout.htm). Larry
