A local area Network needing help please

[outhere]

HI,
Hope i chose the right forum.)
Here's my situation, im sure someone will have an easy answer for me.
I have one DSL connection going into a Linksys DSL router, then uplinked to a Netgear Fast Ethernet Switch which is then feeding 12 PC using win98si and three using win2000.
Up till this point all is great.
What is happening now is that there is an other small network in the back office just sharing files via their ethernet cards and file and printer sharing protocols installed. I just finished fishing cat5 cables from my tech room to there offices and now they all want that DSL connection. Theres where the problem lies.
How, without installing a second network card in each of their PC's could I have that DSL connection while still keeping their PC's networked.
More for thought, the small network in the back are connected to a 5 port router linksys router aswell.

Hope I didnt confuse you all with my blabble...
Perhaps this would help. If I feed the DSLcable into the empty port on the router, will that solve my problem.

Please let me know if I need to be more clear or if my situation doent make sence. Thanks

you can't route packets through a windows 98 machine with 2 network cards (I have tried) in it unless you get some after market software, so I would say you will need to figure out a way of joining the 2 networks into one (well in theory) to get the dsl connection on both networks.

Configure your second router to point to your first router as default gateway.
This should solve your problem

Hope this helps

OK well the plan is in operation, now the troubleshooting...
I fed a cat5 wire into the uplink of the linksys Workgroup hub, into the NETGear Switch. I Set up the IP address on the back PC as 192.168.1.6. From that PC i know the signal is OK because I can access the Linksys router by typing 192.168.1.1 into the IE.
What i cant access though is the Internet. The only difference this pc has then the others is that im specifing an IP address so that i can add more pc's to this network for file sharing as well. SO I Beleive the question at hand here is how do I go about configuring my router to accept these IP addresses.
Thanks for all your help; your comments are much appreciated!!

One of the router ports should have been setup with the same IP range as the rest of the PC's. Also you need to setup a static route to the other router so that all requests are sent correctly.
