Warning: This information is only for encoders running version 8.5 and above.
Encoders running version 8.5 and above will always run with a firewall enabled.
By default:
Unless listed in the table below, the firewall blocks all INCOMING and OUTGOING traffic.
Any cellular connection is always limited to the ports required to connect to the network and then connect to EdgeVis Server, and never has any open listening port.
You have the option to enable a Strict mode on the firewall that disables more ports on the secondary services on your encoder.
Table of open firewall ports
Note: Entries coloured in red below signify which services will be blocked if you enable Strict mode - regardless of your encoder's functional configuration.

(#) - The web server can be disabled and these ports will be blocked.
(*) - These services are disabled by default. It is not possible to use these services on different ports, so all external services must use the default port setting.
($) - These ports are the default for ONVIF and RTSP - if specified by the user, non-standard ports are also supported and will be automatically opened by the firewall.
Y = Available.
N = Blocked.
