Networking segments/ability to share files!

[rflora]

Hello,

I have two LANs.
- LAN1 has IP addresses of 192.168.1.x
- LAN2 has IP addresses of 192.168.0.x
- Both LANs have subnet mask of 255.255.255.0

My objective is to connect these two different segments togethers, without changing IP addresses of the networks. The reason why I'm splitting my network into two networks is, clients on LAN1 share file amongst themself very often, so they slow up the network! But they every once in a while do need to share file with LAN2 as well, so they have to have access to LAN2 as well and VISE VERSA.

I have tried to connect them using a Linksys router BEFW11s4. I was able to PING from LAN1 to LAN2 by having the LOCAL IP of the router same as LAN1 IPs. And I had connected LAN2 to the WAN port of the router. I wasn't able to ping from LAN2 to LAN1, nor was i able to share any files. I'm not even sure if I can do this by using this router! . (Under 'dynamic routing' set up page, I have it selected as Gateway.)

Can anyone suggest a better solution, so I can divide my LAN into to different LANs. OR if it's possible to do it by using this router, please tell me how!!!

I would really appreciate the help.

Thanks in advance.

I've checked the Linksys router, and your WAN interface is for ADSL/Cable connection, so you can't simply plug Ethernet hosts to this port. ADSL signal frequencies are on different range than classic Ethernet signals. That is why you could not ping from LAN1 to LAN2 and vice versa. Since this router can be connected to only two subnets - one subnet for WAN, the second subnet for 4 port ethernet switch - I guess you can't do what you need with your router. Cisco 1701 router can do this for you, check out:

I have not worked with Linksys, but looking into user's guide that is available on Linksys webpage, I could not figure out how your new setup could be configured.

Thanks for the reply.

I'm not very familiar with cisco devices/command console. So if I was to really go with that solution I would really have to learn how this stuff works first! which i don't have the time for. I'm just curious, is there any other way i can divide my network into two segments? Is this even a good solution to my problem? (The reason why I'm splitting my network into two networks is, clients on LAN1 share file amongst themself very often, so they slow up the network! But they every once in a while do need to share file with LAN2 as well, so they have to have access to LAN2 as well and VISE VERSA)

If not, then I guess I would have no choice but to go with cisco!

Other than using a router, you can "segment" the devices with VLANs. Your "busy" clients can go on one VLAN, while the rest go on the other VLAN. Not sure if you want to use that solution, as it would pretty much require a layer 3 switch - or at least will cost a lot more than a simple two port fast ethernet router....

VLANs is one solution, but cannot be implemented with your Linksys router, since it does not support any kind of VLAN tagging protocol, like IEEE 802.1q and ISL. To solve your problem, you will need to switch to Cisco or some other company that support what you need to acomplish. I have checked other Linksys routers, but it does not seem to me any of them can support what you want to accomplish.

If you switch to Cisco, I think you will find here enough information to finish your set-up.

Thanks for all the help!

I just figured out that my switch from Signamax model 065-7530 does support VLAN capabilties. Configuration seems straight forward, but if I have any problems... I'll most likey get help from one of you guys!

Thanks again!
