  • Connecting Two LANS

    Hi guys

    Ive got one place i stay at in sydney and another place i stay at. Both places have wireless routers that share an internet connection with the rest of the LAN. What would be the best way to connect these two LANs

    I was thinking using Cisco 1600 series routers at each end??????

    Any thoughts/advice would be great

    Hi Pulsen,

    I would be glad to help with this but could you draw a simple diagram in mspaint or word and post it so that we could assist better, please? I am having a little trouble picturing how the LAN's are currently layed out.

    In general, a Cisco 1600 can do just about anything you need it to do. If these LAN's are at seperate locations, you could connect them across the Internet with a VPN tunnel. If they are at the same location, you could use routing on the router to connect the two LAN's.

    Thank you for your post!

    Sincerely,
    David Davis

        Hi Pulsen,

        Okay, I understand much better now. Thanks for the picture (nice picture, by the way).

        You should be able to use two 1600's to connect these two LAN's using a VPN. You would need the IOS version that has IPSEC in it to encrypt the traffic.

        That would be one way. There are, in fact, a number of ways to create a VPN between these two sites. You could use Microsoft ISA server, you could use a number of small home office routers, or firewalls like sonicwall, PIX, or others.

        But, yes, the Cisco 1600 would work fine (with the right IOS). In fact, if you are a little unsure how to do this in the IOS, I would use the Cisco SDM product. SDM is a GUI tool for the routers that allow you to point and click and create your VPN.

        Here is a link to about 20 configuration examples on creating a Cisco IOS VPN using IPSEC point to point tunnels:
        http://www.cisco.com/en/US/tech/tk58....html#anchor18

        What you will have to take into consideration is where NAT is being done. Say that NAT is being done on your DSL & cable routers, you might want to use a config example like this one:
        http://www.cisco.com/en/US/tech/tk58...8009486e.shtml

        Honestly, configuring a VPN in the Cisco IOS is not the easiest of tasks. If you don't already have the Cisco routers (would have to buy them), you might consider using a simplier device like this one:
        http://www.linksys.com/servlet/Satel...VisitorWrapper

        This is a Linksys router that does point to point VPN. It will be much easier to configure and perfect for connecting just two offices.

        Let us know how it goes.

        Thanks,
        David

          Thanks david for the help.

          I am doing my CCNA thats why i was leaning towards the Cisco 1600 Routers as a practice (and also im interested in the routers) and i have done some configuration on 2500 series routers.

          I will check out the pages you have suggest and have an attempt with the Cisco 1600 Routers.

          I will let you know how i go

              Hi David

              I decided to go against creating a VPN with the cisco 1600 router, insted i am in the middle of configuring a 2003 as a VPN server.

              Will let you know how it goes

                Hi Matt
                Thanks for the update.
                As much as I like Cisco products, for creating a simple point to point VPN, using Windows 2003 will make your life easier.
                Best of luck to you,
                David
