This tutorial is for setting up L2TP / IPSec VPN server on SonicWALL TZ300 with Firmware version 6.5. This should work for majority of other SonicWALL firewalls as well.
2In the Search field, type SonicWall Mobile Connect, and press Return. 4 Click Free and then Install. SONICWALL SETUP VPN SETTINGS MENU. On this page, click the Edit link to the right of WAN GlobalVPN. See below: VPN SETTINGS GENERAL. Change the “Shared Secret” from yourpresharedkey to a key that you choose. See below: VPN SETTINGS PROPOSALS TAB. Ensure your settings are the same as below: VPN SETTINGS ADVANCED TAB.
- Switch to Classic Navigation Mode if not already in Classic Mode (hamburger icon in bottom left).
- Go to VPN > Settings and Enable WAN GroupVPN.
- Click Edit button next to WAN GroupVPN
- General: Set Shared Secret
- Advanced: Enable Accept Multiple Proposals for Clients.
- All other settings can be left as they are.
- Click Edit button next to WAN GroupVPN
- Go to VPN > L2TP Server
- Check 'Enable L2TP Server' and click Configure
- L2TP Server:
- Enter DNS Servers (normally your internal LAN DNS)
- L2TP Users:
- Select 'Use the Local L2TP IP pool' and enter IP Address range to be issued to VPN clients (this doesn't need to be within your internal LAN subnet).
- User group for L2TP users: select Trusted Users
- L2TP Server:
- Check 'Enable L2TP Server' and click Configure
- Go to Users > Local Users & Groups > Add User...
- Settings: enter Name and Password for your VPN user.
- Group: Everyone and Trusted Users.
- VPN Access: LAN Subnets
That should be it. You can now login from any L2TP / IPSec supporting client.
Update:
I noticed that Windows 10 VPN clients seemingly takes long time to connect to SonicWALL L2TP Server. It stays on 'Completing the connection' stage for 20-30 seconds.
In practice this doesn't seem to affect functionality though - VPN connection is actually established very quickly (2-3 seconds). So you can just ignore 'Completing the connection' status and start connecting to internal resources straight away.
