WRV54G to BEFVP41 tunnel. Cannot see network Please help!!!!

    I have two office networks connected via the two models above. The single router to router tunnel is established and both routers show status as connected. Both are on static IP addresses from the ISP.

    I have followed the instructions in the manuals and put in the routing table to have one network see the other thru the tunnel but no sucess. I cannot ping any machines from one side to the other. But I can ping one router from the other. For that matter I can log onto each router from the other site, so there is a connection there.

    Both networks have different IP addresses, i.e. one is 192.168.0.nnn the other is 192.168.1.nnn.

    All machines are XP pro and TCPIP networked.

    Each individual network is fuctioning just fine.

    My question is do I need to make any changes to the XP machines in order to get through this tunnel. I.I Netbios, DNS, WINS etc.

    Please don't suggest Linksys support, I can read the manual as well as they do, because the 4 odd hours on the phone to them was listening to them read it for the first time to me.

    Any help, suggestions for tools, diagnostics would be most welcome. I am up to 25 hours playing with these beasts and I am frustrated to the max.

    I have seen some posts by Doc Large and others where you have the tunnel open and running but there must be more to do. But What???

    Gonzo,

    where can I get a link to the documentation you're talking about? Did you get it via the wrv54g or the befvpn41?

    Nope, as long as the default gateway on the PC's are set to the relevant router it should work.

    What exactly did it tell you to do?

    TAZ, Gonzo,

    I had someone from "Stinksy" support refer me to this knowledge base article a while back:

    http://linksys.custhelp.com/cgi-bin..._new_search=1&p_search_type=answers.search_nl

    This describes how to configure a tunnel-to-tunnel connection between the RV series routers but I was told it was applicable to the WRV units also.

    Taz, I'm having a moment of cranial flatulence (brainfart); running a wins server on both sides of the tunnel with the lmhosts files configured should allow both networks to see each other, shouldn't it? I've been trying to get my server running with this and it keeps dumping it (I know I missed something so I'm looking at it right now...).

    Still, a WINS server setup (I believe) may be something to consider...

    Depends a lot on what server and client OS your running. NT server uses NetBIOS for name resolutions, hence the need for either WINS or the LMHOSTS file. Windows 2000 and 2003 server use SMB/DNS if the client is running 2000/XP, or NetBIOS for Win9x clients.

    Thanks to both of you for your replies. I took a break from it for a day. I am going back at it tomorrow and I will list the steps that I took in order to get a tunnel connected. Fingers crossed and all that!:)

    Update time.
    From the BEFVP41 side I can now ping all the computers on the other side of the VPN tunnel. Ping time is 30mS, quite long actually. Also the XP machines show all these machines in their network neighborhood and identify them by the correct name. However if you click on any of these machines an error message pops up. "The requested machine is not accessible, please contact your network admin......."

    I reran the network setup wizard but it makes no difference.

    From the WRV54G side I can ping a network machine on the other side of the tunnel but none of the machines on the other side of the VPN show up in "Other computers on this network.

    So ping both ways but no ability to see the machines via the network.

    Your comments and suggestions are appreciated. Thx.

    You could try reducing the size of the MTU at each end and see if that helps.

    Already took max MTU from 1500 to 1492, no change. Do you have a suggestion for how far to go. 1100,1200, I am not sure where to start at?

    The lowest you want to go is 1350, maybe 1300. Any lower than that and you'll start seeing "definite" slow downs (web pages) in performance...

    Okay, I'm losing sight of the original objective. Are you just wanting to ping the other computers, or see them in network places, or is there something else intended? :)

    I would like to have the two networks on either side of the tunnel to have full connectivity i.e. as if the tunnel were not there.

    So yes I would like to see the computers in Network places and I would like to share files and transfer information seemlessly.

    Unfortunately all I can do is ping across the tunnel at this point.

    Alright,

    try opening the firewall to all traffic from only "those computers you want to see each other" be enabling ports 137, 138, and 139. Again, these ports should have only those "specified" computers you want to see each other as being able to utilize these ports.
