Sonicwall VPN Connectivity

I recently configured VPN connectivity on a Sonicwall TZ 190 series.Just thought of making a note on the configurations done.A site to site vpn between our corporate office and a branch office at chennai.The connectivity seems to be fine and working.VPN on a sonicwall can be configured as either Site-to-site VPN or a WAN Group VPN.A site to site VPN is enabled when we need to connect a sonicwall wireless router to a sonicwall device where as a WAN group VPN is configured when we require remote users to access the device via VPN connections.The sonicwall here was configured as WAN group VPN as we need to access this remote device.

The IKE phase 1 key method as set to a preshared key but the default key can also be used here.The security settings was set to a typical sonicwall default settings which actually works well in most of the organisations.The user authentications were set for trusted users and once set I get the congratulatory screen from sonicwall.Logoff and login to sonicwall,click on the VPN button and then check on the enable box to activate the VPN.

The next thing to be done was to create a user.This can be done by clicking on the user button - local user where a user can be created with the password required to connect to the VPN device.

Now as we are going to connect the sonicwall via a Sonicwall Global client VPN client software had to download it from the Sonicwall website.A simple normal installation of the software on the client machine.The only thing which needs to be chosen is in respect to the connection type.There are two types of connection scenarios which can be created,either a remote access or as an office gateway.I chose the remote access scenario as I had to connect to the remote device via web.The other option can be used in a situation where we need to secure a wireless connection to a sonicwall SOHO TZW.

And finally by specifying the remote IP address and the passkey,username and password I could establish a VPN connectivity with a TZ 190 located in chennai.

Terminal Services : improper encryption level error.

I faced a situation while using terminal services.It echoed an error saying you do not have proper encryption levels to access this session.

After doing a bit of workarounds this was the possible Reason : The existing connection that was configured under Terminal Services Configurations (tscc.msc /s) didnt work properly and hence the most common solution to such a problem was to delete RDP-TCP connection and re-create the same in Terminal Services Configuration.
