Sensors do NOT support the use of a proxy server, application or web filtering solution when retrieving updates or communicating with Pulse. This is because the sensors use a customized implementation of SSL and bi-directional authentication to ensure secure communication is maintained at all times.

The following exclusions are required for all sensors being used as a "stand-alone" device and *not* communicating with Pulse

Allow TCP port 443 to "updates.pwnieexpress.com", which is assigned to IP 3
4.194.83.115
Allow TCP port 443 to "kalirepo.pxinfra.net", which is assigned to IP's 3.82.30.60 and 52.21.148.79

The following exclusions are additionally required for all Pwn Plug model sensors communicating with Pulse. Note the value of "subdomain" in the FQDN is specific to the Pulse subscription the sensor is to be registered with.

Allow TCP port 443 to subdomain.pwnieexpress.net, which is assigned to IP's 54.174.109.28, 52.87.33.210, 63.33.5.93, and 34.253.102.92
Allow TCP port 443 to sensors.subdomain.pwnieexpress.net, which is assigned IP's 52.55.157.222, 3.219.15.36, 34.249.171.250, and 54.72.182.78

The following exclusions are additionally required for all Pwn Pro model sensors communicating with Pulse. Note the value of "subdomain" in the FQDN is specific to the Pulse subscription the sensor is to be registered with.
