Connect 2 different Networks to access the resources

September 18, 2012 at 08:19:37
Specs: Windows 7
Hi

I have two seperate networks 192.168.1.1 and 192.168.2.1.

192.168.1.1 is the one which is connected to the ISP Provided router for internet access. 192.168.2.1 is used for in house testing lab.

For these, I use LinkSys WRT54GL router with dd-wrt firmware.

I would like to configure the network in such a way that each of the machines connected to the network(192.168.2.1) also be able to access the resources(shared folders, printers) available in the network(192.168.1.1) and also access the internet.

Would greatly appreciate the basic steps to configure this network design and make it work.

Regards
JoTh

Are you saying that both of these subnets are actually on one physical switch and are not on a vlan? If so then why not change default subnet to include a larger subnet.

Very simple subnet would be to use class based of 255.255.0.0.

If you mean that you have one subnet connected directly to the isp and that you also have a second nic that connects to lan via switch then the normal way is to connect switch to isp.
One can also set the single computer to allow both nics to bridge each other. I can never find that since I can't remember the exact phrase to search for. I know ms pages have it someplace.

They are on seperate routers(LinkSys WRT54GL). I wanted to link these two together so that any users on any of this network can access the resources on either network as well as access Internet.

you need to make one network for all to get what you want. You will not be able to accomplish this with your present ip plan.

In other words, you simply need one network.
So simply change routers ip address from 192.168.2.1 to 192.168.1.2.
After that, you have only one network 192.168.1.x / 255.255.255.0 and each computer can use everything.

So simply change routers ip address from 192.168.2.1 to 192.168.1.2.

You would want to interconnect the routers LAN port to LAN port and do the above on the downstream router's LAN side.

For more in-depth info on setup simply click on my name above in this response and read my “how-to” guide titled, “Add a second Router to your LAN

DD-WRT is pretty advanced. Might be also able to make a tunnel between the two. I haven't ever used it but I know there are a lot of features. If not a tunnel then a connection. Again not sure how much you can configure them. Might be able to set an IP on on port even.

mortneff

I appreciate you're trying to help, but in this case, you're not.

The simplest solution here is to put both routers in the same subnet.........period, end of story.

As to recommending something you're not familiar with, that makes no sense at all.

You really are an odd person CurtR. You do know that the subnets are actually connected in his situation. The changing of subnets on a single physical lan doesn't change the fact that they are connected already. There is no security when they are not on vlans.

How old are you anyway? Your posts make me think you are a very young person.

Actually mortneff they are only connected one way which is what the problem being addressed is about. They are not on a single lan but two lans.

internet<>router1 lan<>router2 lan

.2.1 can talk to .1.1 but 1.1 can't talk to 2.1 due to no gateway entry to 2.1 since 1.1's gateway is to the internet.

This is a well known issue and so is the solution which is to configure the 2nd router as a wifi switch

Hi Guys

Thanks for all your responses and help in this issue.
As I mentioend earlier "The two networks are on seperate routers(LinkSys WRT54GL). I wanted to link these two together so that any users on any of this network can access the resources on either network as well as access Internet.

I am expecting a 2 way communication between the 1.1 equipment and 2.1 equipment.I am also expecting that few more additional networks(3.1 or 4.1) will be added in the future and they also need to be linked together to this 1.1 and 2.1.

Looking for your assistance.

Regards
JoTh

You will need a Cisco router with the ability to route multiple subnets. This is a full blown router not a soho router like a linksys. It will need enough ports to support this setup and you will need to learn how to configure it via CLI.

Good luck!

I may be odd mortneff but at least I know networking. I also know enough to not start posting responses in forums where I don't know anything about the subject matter.

I'm not going to repeat what wanderer already posted in response to your reply but I will add to it.

There is no security when they are not on vlans.

Actually, there is. Properly configured subnets with firewalls in between work pretty darn good too. As a client on a LAN in one subnet, you tell me how you'd hack into another subnet without having access to routers and routing tables?

As to VLAN's, I work with them every day. There are many reasons why one would use a VLAN and security is one of the top reasons. But here's the problem. This conversation is about a Linksys SOHO router. Specifically, a WRT54GL, a model I'm very familiar with (I own one). If memory serves me, the default (Linksys) firmware on them doesn't do VLAN's and even if it did, you have no way to assign different VLAN's to separate ports as it's not a managed switch and, you'd still require a router between VLAN's to route traffic.

As for your crack about my age.....you're showing your immaturity by saying what you did. I suspect anybody reading this thread who cares, will know which of us is a mature adult and which isn't.

I guess the OP decided all the help meant he should call in a person to fix it. I guess you did help him out.

Joth.

I have a similar project and have posted here and hopefully will get some ideas. Just wondering if you have yours solved and if yes, what was the solution?
