Web: Health Monitor Conntrack Test
Host(s)
UCI: multiwan.wan.conntrack_hosts
Opt: conntrack_hosts
Conntrack is the feature used to track if there is any traffic to
and from an IP destination within the health interval.
Conntrack_hosts option defines the IP for conntrack to track –
usually the icmp_host IP is used.
If traffic to the conntrack_hosts IP is detected then multiwan
does not send a ping health check to the icmp_host otherwise a
ping is sent as normal to the icmp_host.
By default the conntrack_hosts is checked if the health interval is
greater than 5 minutes. This time threshold currently cannot be
manipulated.
Conntrack is generally used to limit the traffic sent on a GSM
network.
Default
Conntrack checks for traffic from icmp_host IP
when health_interval is greater than 5 minutes.
Disable
Conntrack disabled.
Custom
Specifies an IP other than the icmp_host for
conntrack to track.
