RV082 site to site VPN

    Hi All,

    I'm getting ready to buy 2 RV082's to link two offices together. I have some questions regarding how my domain will react to two different subnets. Here is how the setup will be:

    Site 1
    ---------------
    10 users
    IP scheme: 111.11.12.1 - 111.11.12.255
    Subnet: 255.255.255.0

    Site 2
    ---------------
    10 users
    IP scheme: 111.11.13.1 - 111.11.13.255 (proposed, not cast in stone)
    subnet: 255.255.255.0

    Site 2 will contain my Windows Domain controller. Will my users in Site 1 still be able to log onto the domain and see the pc's in site 2?

    Site 2 will also contain a w2k3 Terminal Server that the users of site 1 ABSOLUTELY will need to be able to get to over the VPN.

    I'm worried about the 2 sites not being able to interact with eachother because of the different IP schemes, but if my understanding of how VPN works, it is necessary to have different schemes at each site, correct?

    Thanks in advance for any help/suggestions :)

    Hi mbisson,

    i have a situation that is likewise:

    http://www.linksysinfo.org/modules.php?name=Forums&file=viewtopic&t=14906

    i finally got it to getting the vpn routers connect and i can ping, tracert and nbtstat the other computers and or server. However, when it comes to using (loggin in) on the server on the remote location all fail. What i heard so far is that the pc's on the remote office should be able to log onto the server. But they won't. So i am probably dealing with some sort of dns problem or acceptance by the server.

    If you have resolved your problems please let me know, i'll do the same :)

    Maybe there is anyone else that is a routing expert?

    Thanks
    Michiel

    Mbission, there's no reason why you're users shouldn't be able to get over to site two as long as your tunnels match on both sides and your users have valid user accounts on all servers (AD with single sign on). The whole intent of having vpn routers at both sites is so "each computer" does "not" have to have vpn software, which I'm sure you already know.

    There's nothing wrong with your hypothetical ip schemes because you want them to be different; if they weret eh same, the routers would not synchronize because of thinking the requesting router was on the same segment (thus, dropping the connection attempt).

    Take a look at the simulator:

    http://www.linksysdata.com/ui/RV082/1.1.6.14/VPN-Client-to-Gateway-IP-Only.htm

    The tricky part is if both of you're sites have static ip's or dynamic ip's. If you do have dynamic, just register at dyndns.org for an account and you'll be fine. The "only" reason people fuss about having a static ip is because of the isp doing a refresh that will change your endpoint's ip address and leave your road warriors with a connection. A dynamic dns will save you from all this (it ain't no big deal)...

    Look for a linksys user named "Ye Old Stonecat." He's one of the members who uses the RV082 series the most.
