Tutorial: Turn Off Multi-Daemon Mode and Use Only TCP or UDP⁠

Overview⁠

In Access Server, multi-daemon mode optimizes performance by running multiple OpenVPN daemons, one for each CPU core, supporting both TCP and UDP protocols. However, there are scenarios where you might need to turn off multi-daemon mode and use a single daemon instead.

Option 3: Manage this setting in the Admin Web UI⁠

1. Sign in to the Admin Web UI.

2. Click VPN Server.

3. On the Network Settings tab, scroll down to the OpenVPN daemons section

4. Select your Protocol from the drop-down box:

   • TCP and UDP is multi-daemon mode.

   • TCP will run only a TCP daemon.

   • UDP will run only a UDP daemon.

5. Click Save and Restart.
