    Connecting two routers to each other?

    Recently I got a second wireless router, along with a second DSL line. I'm planning on running any bandwidth intensive applications on a computer using the second line, and the other devices will use the first. The problem is, I want to be able to ssh into the computer, but it's not using the same router. Is there any way I can connect the two routers together, so that a device connected to router A can communicate with a device connected to router B?

    Re: Connecting two routers to each other?

    You really have two independent networks. Set up router B to do port forwarding of whatever port is used for SSH (22 if default, or whatever you changed it to if not) to the computer on network B. Router A should not need any special setup.
    Any follow-up information on your issue would be appreciated. Please have the courtesy to report back.

    Yeah I know they're independent.

    How do I set up port forwarding to the second router?

    There is also http://portforward.com/ which is a very popular site, and has insturctions for a great many routers.

    Re: Connecting two routers to each other?

    With this setup, can computers on router A communicate with computers on router B and the other way around? And if so, how would I SSH into the computer, what internal IP adderss would I use to connect to a specific computer?

    I'll admit I haven't checked the links (perhaps I should). My perception of port forwarding is that all requests for a specific port (e.g. 22) would be forwarded to a specific computer. (probably not what you had in mind)

    Re: Connecting two routers to each other?

    Hi, here is a little visual and starting point for you.

    computer A
    computer A's IP (192.168.1.102)
    computer A's "listen" port (2224)
    computer A's ROUTER IP (75.120.35.104)
    computer A's ROUTER Portforward port 2224 to 192.168.1.102

    computer B
    computer B's IP (192.168.1.103)
    computer B's "listen" port (2225)
    computer B's ROUTER IP (75.120.35.105)
    computer B's ROUTER Portforward port 2225 to 192.168.1.103

    A to B ssh -p2225 user@75.120.35.105 (B's listen port and router ip)
    B to A ssh -p2224 user@75.120.35.104 (A's listen port and router ip)

    This is of course After you set up ssh on both networks.

    *Port forwarding is router dependant...
    search....(example) Linksys port forwarding..

    * IMPORTANT * be certin to set security and have keys once you have it all
    figured out...if not...atleast do ..
    Code:
    sudo service ssh stop
    to turn off ssh while you figure it out.
    have fun..

    So this has to go through the ISPs of both routers instead of directly? How fast would this be (latency, bandwidth, etc)? The main reason I ssh between computers is so I can use scp to transfer large files without needing to use a flash drive. I assume going through two ISPs and two VPNs in a long detour around the world would be very impractical when the two computers I want to connect are probably only 50 feet away, or less.

    Is there no way to directly connect the routers, via Wi-Fi or even solid Ethernet?

    Re: Connecting two routers to each other?

    Hi,, the speed will be determined by your current
    isp speed,your internal processor,and type of modem/router.
    the distance is not important. I have a very like set up
    running 2 routers on 2 different networks. one is Fios
    one is not. I dont see any lag when doing local or sharing
    files with someone 3,000 miles away. I would imagine there
    may be a different or better way,as i am no expert i only
    set it up to work with the knowledge i had. Try it, if nothing
    else its a nice learning process.
    good luck !
