Unfortunately the service contract is up, and cheapo management refuses to pay for the renewal. I think the reasoning is that early next year there are plans to upgrade/update the corporate network, and sonicwall will most likely be out of the mix. They do not want to pay for a year when they will not have the device for another year.

This started happening on older firmware versions, and we have since done 2 firmware updates on it hoping it would resolve. We are currently at the newest firmware available for this sonicwall: 5.9.1.7-2o. I also think this product is not going to receive anymore updates.

The netextender version that they are using is 7.5.223 which is the version that is published by the sonicwall on this firmware version, but I have also tried connecting from a machine with netextender version 8.6.256 which i believe is the newest version, and I have the same troubles connecting.

I'm trying to connect to my office using sonic client and consistently failing.Actually sonicwall client informs me that connection to network is established, but when I tried to access one of the computers remotely using remote desktop it fails.

I have seen this same problem with Checkpoint's VPN. The issue is basically an overlapping IP scheme on your home network with that of your company. So if your office uses 192.168.1.1 in one of the networks and your home uses the same scheme then the problem surfaces. Try changing your home network to something else and see if that fixes it. An alternative is to check the settings of the VPN client, Checkpoint has an "office mode" that alleviates this problem.

Here is update on my connection problem.I tried to connect yesterday (in order to document connectivity issue) expecting error.On my surprise I was able to connect. I changed nothing on my router and on my computer since last failed attempt. I noticed that ip given was different from the one when I was failing to connect. That leads me to believe that the problem was indeed IP overlapping as EasyEcho pointed out. That is the reason I'm accepting his response as answer.Thanks again to everybody that tried to help me.
