Order now | Download | FAQ
Navigate to System Settings > Servers > Add New Server in WHMCS admin area.

Step 1: Name and Hostname

Name — a descriptive name for your convenience (e.g., "Mikrotik VPN Router 1")

Hostname — the hostname that resolves to your Mikrotik router's IP address (e.g., vpn.mydomain.com). You can also use a dedicated domain. The important thing is that the chosen hostname resolves to the IP address of the Mikrotik router in your DNS.

Step 2: Assigned IP Addresses
In the Assigned IP Addresses field, enter a list of IP addresses that will be issued to VPN clients — one IP per line.
These IPs will be assigned to WireGuard peers as their tunnel addresses. The module automatically allocates the first available (unused) IP from this pool for each new service.

Enter the list of IP addresses for VPN clients

Step 3: Server Details

Select the "PUQ Mikrotik WireGuard VPN" module from the Module dropdown
Enter the correct username and password for the Mikrotik router
Set the port (default: 443 for HTTPS REST API)
Check the Secure checkbox if using HTTPS (recommended)

Server connection settings with module selection

Step 4: Test Connection
Click the "Test Connection" button to verify that WHMCS can communicate with the Mikrotik router via REST API.
A successful connection will confirm that:

The Mikrotik router is reachable
The credentials are correct
The REST API is enabled and responding

Next Steps
After adding the server, proceed to Product Configuration in WHMCS.
