This sets a flag on the listening socket to modify the behaviour of grep_sock_info. When this flag is set, grep_sock_info will only consider the listening IP a match if the IP is found in the system's current list of local IP addresses. If the IP is not currently local, then the matching IP is ignored. If the virtual flag is not set on the socket then existing behaviour used instead. This feature is intended for scenarios where you have two Kamailio nodes in active/active setup, with virtual IPs, where you need to be able to listen on a virtual IP but it may not always be active locally. With this flag applied to a `listen=` socket, Kamailio will only consider traffic destined to this IP local, when the IP is actually active on the system, and other times the match is ignored.
