QuickVPN works from ADSL but not dialup

    Hi all
    I have the WRV54G and installed the latest beta firmware 2.38. I was using the release firmware but getting the same result.

    Laptop->Dial-up->Internet->ADSL modem->WRV54G
    During the setup i was testing from a dialup account and it would get to "Verifying Network..." and never make the proper connection. Although i did find that i could setup a remote desktop connection even in this state!!!

    Laptop->Netgear FVL328 ->ADSL->Internet->ADSL modem->WRV54G
    I then attempted from an ADSL connection (using the same computer) and it has worked perfectly.

    I am quite new to all this networking stuff and am wondering if there settings on a dialup account that need to be modified for this to work?

    On a general note, what protocols etc (not sure of terminology) does quickVPN acutally use... DES3,SHA-1 ??

    Any suggestions are much appreciated

    Quickvpn uses IPSEC. The thing to keep in mind is that quickvpn will not work if you have another vpn client loaded on the same machine. Before ruling out dialup all together, try another dialup connection to see if you're still getting the same problem. Look at it as being a process of elimanation...

    I just caught something. You're using an ADSL modem? I say this because I'm also (x-modem ce) to use my wrv. Are you using the same modem, and if not, what brand are you using?

    Have just tried from another computer using a dial-up PSTN modem ... does the same thing unfortunately. This computer doesnt have any pre-existing VPN software either. Is there a log file that is being generated anywhere that i can check out ?

    The ADSL modem is a alcatel speedtouch home POTS ...

    Oddly enough, before I put my wrv54g back online, I was running my WAG54g. It works perfectly! The only downside was that it maxed out at 5 vpn tunnels. I had no problems connecting to the tunnels with either adsl/pppoe or dialup connections. Since putting my wrv54g back online, I haven't been able to establish a vpn connection across dialup. It's looking pretty bad if this is a firmware issue. Fortunately, I just got firmware version 2.37.13 from Linksys and I've going to give that a try.

    Currently I'm running 2.36.5 on my router to annotate what does and doesn't work. The issue you're having might be firmware. See if you can go down to a lower version to see how that makes it ace...

    Longtime, no post...

    My bad for getting back so late on this. As an update to a question you asked a few weeks ago, quickvpn users Ipsec, 3DES and MD5. As far as connecting over a dialup, I've never been able to get quickvpn working from that standpoint. Minus any other thoughts, my belief at this time is the issues lies with MTU and the speed (or lack therof) of the connection.

    My personal opinion, stick with broadband for quickvpn connections...

    I'm pretty sure I've had it working over dial-up, that was with an earlier version of the firmware.

    do you remember which particular version? I've been trying (for shitz and giggles) with the latest firmware (2.38) and haven't been able to get past the Linksys's equivalent to window's "blue screen of death" (verifying network).

    I don't really need it but I wanted to try and test the functionality over dialup in case I have the oddball dialup vpn support request...

    I think it was either 2.25.2 or 2.32.2, but it was a long time ago so can't be certain :?

    If I get a chance I'll test it out again.
