    Site-to-site VPN Cisco 1811 - wireless

    Thank you in advance for your help, experts.

    I have a family friend that owns a small company with 2 locations (10
    pcs on one end, and 5 on the other). They have static IP addresses -
    their internet connection is a Wireless connection (DSL and Cable not
    available).

    He would like to setup some way for the PCs at both locations to be
    able to talk to each other. I am thinking about purchasing 2 x Cisco
    1811 routers, connecting them to the ethernet connection provided by
    the wireless devices located at each location, and setting up a site-
    to-site VPN connection using these devices.

    First of all, does this sound like something that's workable/doable?
    Second, if it is doable, does anybody know these routers well enough
    to tell me if it is something that I should be able to do within the
    SDM (GUI), or if there will be a lot of command line configuration
    required. And, finally, can anybody give me the steps I would have to
    perform to get this to work properly - or a website I can go to that
    will give me a step-by-step procedure to complete this task with these
    routers.

    We don't have a ton of money, just enough for the equipment, and want
    to make sure it's something that will even be possible if the
    equipment is purchased in this scenario - before delving head first
    into it. And if it is possible, we want to make sure it's something
    that we'll be able to actually do ourselves - hence the step-by-step
    procedures requested.

    I am very tech savy, and actually had my CCNA quite a few years ago,
    so I know my way around most routers (for the most part). However,
    things have changed, and I want to make sure I can handle this before
    commiting to him.

    Thanks a bunch, experts - you're my saving grace...

    What kind of wireless are you talking about? 3G (CDMA/GSM)?

    That would be doable with a pair of pair of 3G-equipped 881s (or, more
    expensively, with higher end routers with 3G HWICs - but not the 1811,
    which doesn't have 3G.)
    http://www.cisco.com/en/US/prod/coll...78_498096.html

    Set up the 3G cellular interface on each router to access your provider.
    Then configure the IPsec tunnel between the sites. Should work fine.

    I don't know whether or not SDM can configure the whole shebang. In any
    case, the routers should come with tech support to help you get it
    set up.

    Cheers,

    Aaron

    Aaron, thanks. It's a wireless provider, not a cellular (3g)
    provider. It is basically radio waves that come into the building
    through a wireless receiver - and they basically give us an ethernet
    port. It's practially the same thing as DSL/Cable - except it's
    wireless... No cell phone cards or anything like that.

    I would also like to know how to "Then configure the IPsec tunnel
    between the sites. Should work fine.". That's the part I'm not sure
    on, and wondering if there's maybe a step-by-step procedure? Thanks
    again.

    Robert,

    My $.02 worth:

    Having worked with Cisco routers in the past and also having setup
    dozens and dozens of branch locations (mostly bank branches) we
    eventually switched to low cost routers that offer VPN ability and
    used the Netopia 33xx series. While they have a command line with
    syntax quite similar to Cisco, they default to a telnet formatted
    interface which allows full configuration including one or many VPN's.
    They support all the features of most low-mid level Cisco's with the
    exception of the proprietary options.

    They tech support and online technical database is one of the best
    I've seen. And, unlike Cisco, you don't have to pay an arm and a leg
    every year. You could look at some at Netopia.com (now owned by
    Motorola) and check out pricing at provantage.com. Look specifically
    at the 3346-ENT models (or spend more on the 4622XL models - but these
    are overkill for your needs).

    Good luck

    He says he doesn't have DSL (or cable) available at these locations,
    so I'll be curious to see how the 3346-ENT will work.

    Do they provide you with a single ethernet port where you can connect
    only a single PC without providing your own router, or does the device
    have multiple ports and/or you could connect your own switch and have
    many pcs access the internet without further hardware and/or software?

    I ask this because it is very likely that the box you got from the
    provider already is a router and provides NAT functionality to translate
    many internal PC addresses to a single external address.

    It will be more difficult to connect another router to such a device
    and then setup IPsec tunnels.

    If you need to ask this, it might be better to ask a supplier to
    configure everything for you, or to go with another manufacturer who
    is more oriented towards do-it-yourself installation of their equipment
    without too much expertise.

    -Do they provide you with a single ethernet port where you can connect
    -only a single PC without providing your own router, or does the
    device
    -have multiple ports and/or you could connect your own switch and have
    -many pcs access the internet without further hardware and/or
    software?

    That's a good question - I'm not really sure. I would assume it's
    just a modem type device, but you know what they say about assuming.

    As far as asking for a step-by-step procedure, it's not that I don't
    think I would be able to figure it out myself, it's that I'd like to
    see an example of performing this operation, so I can see what the SDM
    looks like for this procedure. I currently maintain 3 x Cisco 2800
    series routers for the company I work for, and have setup one site-to-
    site vpn, however, it was done in a completely different environment,
    and it's an older version of the SDM. I just want to see what the
    steps look like using this particular router/SDM.

    Hello Robert,

    if you have not yet purchased the hardware - did you consider to set up
    the whole thing with a little ASA5505 instead of the 1811 at each end?
    It comes with a SSL webfrontend and a wizard within for setting up the
    ipsec site to site.
    Costs for the 2 ASAs should be less, too, I think.

    Regards,
    Claudio

    before you do anything, I would suggest you should call the internet
    provider to make sure they do not block ipsec. I have seen some
    wireless providers that do.
