    is it possible to quick VPN connection from within your own network (for testing purposes, obviously there wouldn't be any use for this otherwise).

    No, you can not connect to your own vpn connection from inside your network. Your best means of testing would be for you to plug a laptop or another computer into a phone jack and connect to your network this way (provided your network connection is a cable modem and not an ADSL connection.) Now, if you have an ADSL connection that has two separate numbers, you could try calling out on one (via dial-up) and connecting this way, also.

    Good idea....I'll try dialup

    Its kind of weird. From outside the network...it says verifying network, then 1 and 1/2 minutes later it says something about gateway couldn't be reached, and a dialogue says something about "gateway can't be reached", but what is strange is that I am connected, and can see network resources until I press the 'OK' dialogue, then it disconnects.

    *heh*

    You're not the first person to have this anomaly occur, redneck. I've yet to see it firsthand for myself but obviously it exists. As long as people can make the quickvpn connection, then everything is alright!

    Doc,

    The only thing I'm afraid of is that because I don't really understand at a technical level what is going on, that maybe it isn't secure, or "protected". For all I know perhaps I am broadcasting everything over the internet (obviously not that bad, but you know what I mean). Do you think its safe to use like that? I was getting good performance though which is positive.

    I'm no securiyty expert (studying for my certification right now) but I would say if you can find some free tools (www.foundstone.com) run your vpn and put some packets through. If you're running something like windows 2000 server (advanced) or something else that comes with a network analyzer, you should be able to monitor the integrity of your tunnel.

    Quickvpn uses 3DES (encryption) and MD5 (authentication). Currently, SHA1 is more effective than SHA1, but that doesn't mean MD5 doesn't do its job. So the best way is to montior the traffic and see if your are leaking info :)

    This is interesting as a couple of my users are having problems connecting with QuickVPN. They experience the error message you described, after "Verifying Network" they get "The remote gateway is not responding...".

    I'm having them try to ping servers when that error message pops up and see if they get responses. That would be interesting.

    Thanks for the idea, this may also help my DMZ VPN problem as well.
