filteringFlag

A value from NF_FILTERING_FLAG enumeration.

processId

Process identifier.

direction

The direction of network activity. Specify NF_D_IN for the inbound TCP connections and UDP datagrams, NF_D_OUT for the outbound TCP connections and UDP datagrams. Zero or NF_D_BOTH mean any direction.

ip_family

Describes the family of IP addresses (AF_INET for IPv4 and AF_INET6 for IPv6).

localAddress

Local IPv4 or IPv6 address as sockaddr_in or sockaddr_in6.

remoteAddress

Remote IPv4 or IPv6 address as sockaddr_in or sockaddr_in6.
