Terminal VPN clients use TCP port 7742.

It is redirected to port ranges 13000:130xx (xx - number of load balanced interface).

  • Default = 1 per 200 terminals.

  • If you drop all input on your firewall, you will have to re-enable incoming connections to these ports. Configuring Server Firewalls

If you manually restart your firewall:

You have to run this command: . source /batm/vpngen/firewall.rules

  • Inserts load balancing and firewall rules at the top of the firewall rules table.

  • The rules are loaded automatically when the server restarts.

Port 7741 can be safely closed after all terminals are connected through the VPN.

  • Open port 7741 as needed to reconnect these orphans.
