Dueling subnets

    I recently added an RV042 to the church's network so that staff could access church resources located on a Linux server from their homes. After a GREAT deal of time with tech support to no avail (really odd--I've always had great experiences with Linksys support), I finally managed to connect to the router from my home. To do so, I had to change my home network from 192.168.1.x to 192.168.2.x to avoid routing problems with the net at church which is also 192.168.1.x. Connection with QuickVPN then went smoothly.

    Until I tried to access a share on the Linux server.

    Of course, I couldn't see any of the computers at church presumably because I am now on a different subnet. I have an awful feeling I'm being real dumb here. What should I do to access shares from the church from home?

    You should be able to see the machines if you access them via their ip.

    Turns out the problem isn't with the subnets -- it's netbios over ethernet, which QuickVPN doesn't support. Without that, nothing shows in Network Neighborhood.

    I tried setting up a tunnel, but the docs are so poor, I was unable to do so. A tunnel and the XP VPN client WOULD support netbios over ethernet (I believe), but I cannot get that to go. Is there a nice howto somewhere written in understandable English?

    Dunno about the tunnel. What you could do, although the learning curve is also steepish, is to install OpenVPN on the church's Linux box, and then port-forward any openvpn connections from the church's internet connected router directly to openvpn on the Linux box. As (I figure) the VPN connection now terminates on the Linux box, routing of netbios stuff should not be an issue.
    This way you don't need the RV (or any other VPN router).

    Note though (and I'm not too sure about this), that you should be able to, with your current setup, connect to the shares as \\ip.address.of.box or \\FQDN.of.box, like \\linbox.church.net

    just add the share names of the church in you PCs LMHOST file, or use the \\192.168.1.x\sharenames\

    Many thanks to all :) . I got the shares by IP, and since the laptops are going to church personnel for whom networking is not even deuterocannonical (OY! I made a religio-computer joke....uh...sorry), I'll set them up by mapping network drives, show them how to click QuickVPN, and I should be good to go.

    The other part of this puzzlement is how to set up a not-QuickVPN tunnel. The docs were apparently prepared in Ugaritic, translated by Tibetan monks and the resultant text randomized by Madagascar macaques :confused: Is there a clear howto someplace? All my Googling has turned up is people whining "Is there a clear howto someplace?" What I'd like to do is to set up a tunnel that can be reached by an XP machine (or one of my Linux boxes) using XP's client (or some Linux equivalent). I don't run Vista and am not bloody likely to, either.

    Many thanks, again.

    you could always use the built in PPTP server on the router and setup a PPTP client on the windows/linux pc.
