In this article:

    Twingate Clients establish a connection to Twingate's Relay infrastructure on a specific port range (30000 - 31000).

    Some internet access points sometimes block outbound ports other than the typical 443 and 80.

    The best way to test this is to use nmap (native on Linux, available on Mac via brew and on Windows as a binary)

    The following shell command will test outbound port 30001:

    time nmap -p 30001 portquiz.net
    

    The expected output should look something like this:

    PORT      STATE SERVICE
    30001/tcp open  pago-services1
