About L2TP VPN Protocol
Layer 2 Tunneling Protocol (L2TP) is one of the most widely supported VPN protocols, offering excellent compatibility across different devices and operating systems. L2TP provides strong security when combined with IPSec encryption and works reliably behind NAT firewalls, making it an ideal choice for L2TP VPN on Mac.
Why Choose L2TP for Mac?
- Universal Compatibility - Works with virtually any VPN gateway
- Strong Security - Uses IPSec encryption with AES-256
- NAT Traversal - Reliable connection through firewalls and routers
- macOS Integration - Excellent support in VPN Tracker and native macOS
- Stable Connections - Automatically reconnects after network changes
L2TP VPN Setup Requirements and Checklist
Before setting up your L2TP VPN on Mac, you'll need to gather specific information from your VPN gateway. This information is typically found in your router's web interface, VPN server configuration, or provided by your network administrator.
L2TP Configuration Checklist
Locate the following information on your VPN gateway or from your network administrator:
- VPN Server Address - Public IP address or hostname of your gateway
- Pre-Shared Key (PSK) - Shared secret for IPSec authentication
- Username - Account name for L2TP authentication
- Password - Password for your L2TP user account
- Remote Networks - Internal networks accessible through the VPN (optional)
Finding L2TP Settings on Your VPN Gateway
The exact location of L2TP settings varies by manufacturer, but here's where to look on popular gateway types:
Common VPN Gateway Locations
Router/Firewall Web Interface:
- VPN Server → L2TP Settings
- Advanced → VPN Server → L2TP
- Security → VPN → L2TP/IPSec
- Services → VPN → L2TP Server
What Each Setting Means
| Gateway Setting | Alternative Names | VPN Tracker Field |
|---|---|---|
| Server Address | WAN IP, External IP, Gateway IP | VPN Gateway |
| Pre-Shared Key | PSK, IPSec Key, Shared Secret | Pre-Shared Key |
| L2TP Username | Account Name, User ID, Login | Username |
| L2TP Password | User Password, Account Password | Password |
| Internal Networks | LAN Subnet, Private Networks | Remote Networks |
Example Gateway Screenshots
Tip: Take screenshots of your gateway's L2TP configuration pages. This makes it easier to reference settings later and helps with troubleshooting if issues arise.
Setting Up L2TP VPN in VPN Tracker
VPN Tracker for Mac provides excellent support for L2TP VPN on Mac – with automatic configuration and reliable connection management. Here's how to set up your L2TP connection:
Step 1: Create New L2TP Connection
- Launch VPN Tracker 365 on your Mac
- Click File > New Protocol Connection > L2TP to create a new custom L2TP connection
- Alternatively, click File > New Vendor Connection and choose your vendor and gateway from the list
- Enter a descriptive name for your connection
Step 2: Configure Gateway Settings
VPN Gateway:
- Enter your gateway's public IP address or hostname
- Examples:
203.0.113.10orvpn.company.com - If using Dynamic DNS, enter the full hostname
Topology:
- Default Setting: VPN Tracker will usually select Host to Everywhere, which routes all your network traffic through the VPN
- Verify Configuration: Confirm that this matches the way your VPN gateway is set up
- Split Tunneling Option: If your administrator has configured a Host to Network connection (also called split tunneling), select this option from the dropdown menu and specify the exact remote network address(es) that should go through the VPN
Step 3: Configure Authentication
Pre-Shared Key:
- Enter the PSK exactly as configured on your gateway
- Case-sensitive - ensure exact match
Account Credentials:
- Enter the username and password you configured on your gateway when setting up the L2TP VPN
Step 4: Configure DNS Settings< (optional)/h3>
- By default, VPN Tracker assumes DNS is in use and the settings are handled automatically by the VPN server
- To override the default settings and add custom DNS settings, uncheck the box Receive DNS settings from VPN gateway Learn more about configuring DNS in VPN Tracker →
Step 5: Advanced Settings (If Needed)
VPN Tracker's L2TP VPN profile assumes certain settings on your VPN gateway. It's important you check that these settings match up with the settings in VPN Tracker to ensure your VPN will work properly when you try to connect later.
Switch to the Advanced Options tab to make changes to the setup.
When to Use Advanced Settings:
- Custom Encryption - If your gateway uses non-standard settings
- NAT Traversal Issues - For problematic firewall configurations
- Specific Routes - For complex network routing requirements
- Connection Timeouts - To adjust keepalive and retry settings
