Viewing Active Network Sockets¶
The Diagnostics > Sockets page presents a list of active TCP/IP sockets for both IPv4 and IPv6 used by the firewall itself.
This list is useful for determining which IP addresses and ports are in use by various system processes or packages. It is interpreted from the output of the FreeBSD command “sockstat”.
By default, only listening sockets are shown. Click Show all socket connections to also display sockets in use by the system making connections to external hosts.
The output of this command only shows sockets used by the firewall OS for daemons or other programs on the firewall. It does not show connections for traffic passing through the firewall.
