Two Networks One ISP

Management where I work wanted to isolate the office computers from the shop computers. They do not want to share data between the two areas nor see them in the network neighborhood, but they want to share a common isp connection. I have hooked up a Linksys Wireless Router from the cable modem as the incoming connection and this serves the shop area. I have daisy chained a Netgear router for the network in the office area. Doing this let me accomplish isolating the two networks from each other. This appears to be working fine. I am able to access the Internet from all computers and share data between the two different networks. The first network system has 15 computers running and the office system has 3 computers. I have not disabled DHCP on my second router.

My question is can I expect to see problems in the future with my setup? As I have stated, it appears to be working properly at the present time. I hooked it up today Friday, 12-07-2007.

Thank you for your support.

 

If you are lan to wan you have 2 networks and should be on seperate subnets. If you went lan to lan you basicly used the second routers as a switch. If your second router is default with a different subnet you will find that you can go out but the upstream routers can not come in, unless you opened a hole in the FW. I have 2 routers connected down stream of the 1st. And I put on on a VLAN to have total isolation form my main computers.
