crossing networks

[bidder5757]

Hi. I'm after a little advice (not being a professional network admin). This'll probably cause you guys to roll your eyes and mutter about amateurs... but I'd be grateful for any help anyone can give me

I have a cable modem connected to a netgear router to which three PC's are connected. Everything works fine. the router IP is 192.168.0.1 and the subnet is the usual 255.255.255.0

One of the ports on the router is connected to another (LinkSYS) router elsewhere in the building which allows access to the internet using the first router as a gateway. No worries there.

However the second router has an IP address of 192.168.1.100 and I don't know how to get the PC's on the two networks sharing files, printers, etc. (all the subnets are the same: 255.255.255.0) I tried setting the second router's IP address to 192.168.0.100 but it stopped working (even though it detected the gateway address, it just couldn't use it for some reason).

Does anyone have a fix for this? Do I just set the subnet masks to 255.255.0.0? and if so where? In the routers, PC's or both??

Any help would be gratefully recieved. Thanks.

Hi, I'm not a Network admin, just got started on the CCNA ICND Book.

But I think your problem is not subnetting but the network properties on each workstation. If you are on a Windows enviroment rightclick on the network neighborhood icon, properties, file and printer sharing, check the two boxes.

I hope this helps.

Several things to look at here:

1) Layer 1 connectivity. Is the WAN Port on your Linksys router connected to one of the ethernet "lan" ports on the netgear router?

2) Layer 3 connectivity. The WAN port on your linksys router should be in the 192.168.0.0/24 network.

3) The workstations connected to the Linksys should be getting their IP addresses from the Linksys Router, this is by default 192.168.1.0/24. Ensure these workstations have their gateway listed as the linksys router. This will let the linksys perform the routing for that network.

4) To administratively manage the linksys router from the netgear network, you will have enable the remote management configuration (lets you manage it via the wan connection).

5) For the file sharing, etc., follow the previous poster's recommendation(s).

Err.... thanks. I solved the problem by setting the IP address of the Linksys router to be on the same network connecting the cable between the routers to a regular port on the Linksys (vs the uplink port), and then turning off the NAT and DHCP facilities in the Linksys router. That turns it into a pass through switch with the netgear router providing IP addresses. Just what I needed.
