RV042 gateway to gateway VPN & Domain

    Greetings All,
    I talked to Linksys pre-sales about how to connect the network in two seperate buildings. They suggested using the RV042 routers.
    (Interestingly I thought he indicated that they had VLAN capability, but I see no sign of that.)
    I got two RV042 VPN routers. I put one in Building 1 connected to a DSL line with a static IP address. It serves the internet to the local network there. The other router is in building 2 on a cable connection with a dynamic IP.
    I successfully created a VPN Gateway to Gateway tunnel between them.
    The Building 1 network is a Win 2003 domain. I can see the domain from building 2, but not connect to it.
    My objective with the gateway to gateway connection was to make the connection in Building 2 seem like simply another part of the network in Building 1. Unfortunately though, while I can see the domain, I cannot connect to it.
    Any suggestions on this. I thought that the VPN would make it appear to just be an extension of the network in Building 1.
    Thanks, Mike Breeden

    Did you enable Netbios broadcasts?

    Why not:
    - a wireless bridge
    - an optical bridge
    - pull a fiber cable
    - send the signal over two unused telephone lines?

    Did you enable Netbios broadcasts?

    Why not:
    - a wireless bridge - I am 200 feet line of sight window to window. Do you think it would work. Say using 2 wireless n MIMO access points as a bridge? Security would only be so so.

    - an optical bridge - Uhhh. Not sure of what that is. I'll Google. ... do you mean "fabrication of such a refractive micro optical bridge by deep proton lithography" or are you talking about a fiber optic link.... See next question.

    - pull a fiber cable - The other building is across and down the street, otherwise the distance is such that I could likely use Cat 5. It is tempting to string it over buildings and existing lines, but I'd get sued.

    - send the signal over two unused telephone lines? - Not clear on this. I have a good IP connection. The VPN tunnel exists. I could make a slower link with phone lines (theoretically 128 KBS), but what's the point?

    I have a tunnel between the two VPN routers. I thought that they would act as if they were on the same network segment. I won't be able to test NetBios Broadcast until later today.
    In Network Settings - TCP/IP - Properties - Advanced - WINS tab, is a checkbox to Enable NetBIOS over TCP/IP. Is that what you are referring to. Will that fix me up?

    Thanks much, Mike

    In your situation with 200 feet line of sight I would definitely not funnel the traffic through two broadband connections. A wireless link is going to be:

    - faster
    - cheaper
    - more reliable
    - completely transparent to network protocols

    What should you do:
    - Go out and buy two Buffalo WHR-HP-G54
    - configure them with a fixed IP address, wireless encryption, etc.
    - set them to WDS bridging mode
    - place them at the two windows
    and you are set. The two routers will connect the networks over the wireless link just link pulling a network cable to the other building. You may want to make sure that you hav only one broadband connection, DHCP Server etc. active before you connect the networks and switch to one single IP range.

    Later on for a more permanent placement you may want to purchase two flat panel antenna. At a later stage you may also want to experiment with alternative firmware such as DD-WRT.

    Technically the Buffalo WHR-HP-G54 are a more advanced (the Buffalo has a wireless signal amplifier) version of the Linksys WRT54GL. The Linksys WRT54GL is also a very popular router but has a less powerful wireless signal. I run both the Buffalo and the Linksys at the office, think that both are excellent but would choose the Buffalo for a building to building link over the Linksys.

    I've done a few of these....you need to make sure the PCs at the network without the DC...are using the DCs IP address as their primary DNS server. Also fill in the DNS suffix.

    Wow folks. Thanks for the useful replys.
    Special thanks to DocLarge from another post that gave me the final solution.
    The key problem I had was the mapping issue. Map the drive to the share as \\192.168.***.***\share AND THEN USE THE CONNECT AS selection. It then worked.
    The connection has about a 10X speed penalty when using DES (DES3 was slower). I would love to try it as a wireless. Maybe I will get to if the VPN is too slow.
    Thanks again, Mike

    If the workstation properly joined the domain...and is logging into the domain at the login prompt...you do not need the peer to peer "connect as" setup.

    Uhhhhh. Well it is definately a member of the domain and I was logging in as administrator at the time... I could see the domain, but I had no access to it. All members and shares were hidden....??????
