Hi,

I have a problem here:

When I trying to use Linksys QuickVPN to connect to a VPN (setup with Linksys RV082), but can't establish a connection.

However, when the other person use Linksys QuickVPN to connect to the VPN, it got connected.  He is on the same internet connection with the server, I guess.

So I tried to switch to use Win XP's networking tools to connect to the VPN, and it works. But when I got connected, it kills my internet connection in few seconds.

Does anything body know what is the probme? and I really want to use the Linksys QuickVPN software

thanks,

Jack

First, the problem with the windows VPN can likely be fixed by going to:
control panel | network connections | right click on the VPN virtual adapter and choose properties | Networking | TCP/IP properties | Advanced | General | uncheck the box "use default gateway on remote network"

The Linksys QuickVPN client works well, but can be a little fussy sometimes. On the router on the site from which you are trying to connect see if there is an option to "enable IPSec pass through". Also make sure the router's WAN IP (not LAN) is a true public IP not a private one such as 192.168.x.x A good test is to try connecting to your modem directly, by-passing the router. Make sure virus protection and such is enabled and up to date.  
The following sites have QuickVPN check lists that may help to isolate the problem.

Hi RobWill,

The connection with Windows XP VPN Client is stable now, but when I conncted, I tries to use Putty to ssh to a server that is attached to the VPN, it can't establish a connection.

And I'm not getting anywhere with the QuickVPN.

thanks,

Jack

Windows VPN automatically starts Putty ? That is odd. Afraid I have no suggestions there.

As for the QuickVPN, anything in the check list seem out of place?
When you try to connect a box pops up saying connecting, verifying etc. How far does it get?
Does the VPN log on the RV082 show that it tried to start a connection?

Once either the QuickVPN or Windows does connect try accessing resources by IP rather than name, at least a s a test.

RobWill,

After I connected the VPN (with the windows xp connection), then I start Putty, and tries to use putty to connect to a server that is on the VPN, but putty cannnot make a connection with the server.

I'm trying to fix this problem first, before do anything to the QuickVPN.

thanks,

Jack

I don't know if you can run SSH within the tunnel. All protocols should be allowed but I have never tried. Try a basic ping or telnet. Also the software firewall, if any, on the machine to which you are connecting needs to be disabled or configured to allow the incoming service.

RobWill,

I can't ping it, because the admin diable this feature.
Telnet? I tried it, but it doesn't work, too.

I have disable my windows firewall, too.

Jack

Are the remote and local subnets different? Due to routing issues they cannot be the same. For example if the office is using 192.168.1.x then the remote site will have to use something else like 192.168.2.x, or you will experience difficulties such as yours.

Now, I can ping the VPN, and get something back.

The other person who is on the same internet connection with the VPN(server) is able use Putty to connect to the server.

I still can't use Putty to connect to the server.

thanks,

Jack

I don't use SSH but I wonder if it could be a conflict caused by the two encryption methods being used simultaneously, PPTP and SSH ? Can you try a basic Windows TELNET connection ?
