VPN client connectivity requirements

Our VPN client (VPN Client) is a lightweight application, running in the background on your computer, that enables you to make a secure VPN connection to your devices from within your browser.

The VPN Client uses an outgoing port to establish a secure connection to the x500 IoT gateway.


Below is an overview of the outgoing port and protocols that the VPN Client utilizes, which can be blocked by the computer’s firewall or the company’s firewall.


The VPN Client also utilizes the following local port and protocols, which can be blocked by the computer’s firewall.

9250, 9255(1)TCPHTTPS, WebSocket

1. Port 9255 is only used when stealth mode is activated for connectivity via a censored internet connection (i.e. when located in China).
