PPTP, or Point-to-Point Tunneling Protocol, enables authorized mobile devices, including smartphones, to access your organization’s network. To connect to your Barracuda SSL VPN using PPTP, your remote device must have an appropriate VPN client that supports the desired authentication protocol, preferably MSCHAPv2.
Before you begin
On your organization's firewall, allow authentication traffic to and from the Barracuda SSL VPN. TCP over port 1723 and GRE (IP Protocol 47) forwarded to the Barracuda SSL VPN for PPTP connections to function.
Step 1. Enable PPTP server
On the Barracuda SSL VPN, configure PPTP to allow your remote users to authenticate and connect to the protected network.
- Log into the SSL VPN Web interface.
- Navigate to the RESOURCES > PPTP Server page.
Verify that you have selected the correct user database on the top right of the page.
- In the Create PPTP Server section, enter a descriptive name for your PPTP server.
In the IP Range Start/End fields, enter the first and last IP address of the DHCP range that should be assigned to remote systems connecting via PPTP.
- From the Policies list, select the available policies that you want to apply to the PPTP server, and add them to the Selected Policies list.
- Click Add.
The PPTP Server is now created and appears in the PPTP Server section. You can test the configuration by clicking the Launch link associated with the entry.
Step 2. Create a PPTP connection
On your remote device, create a PPTP connection to the Barracuda SSL VPN.
- Log in to the Barracuda SSL VPN on the client device.
- Go to the Resources tab.
- From My Resources, select the PPTP server and click to connect.
Step 3. Download the configuration to the client device
For more information, see: Provisioning Client Devices.
- From the Resources tab of the client device, go to Device Configuration.
- Tick the checkbox for the PPTP server entry.
- Click Provision on the bottom of the page.
