Web Field/UCI/Package Option
Description
Web: Health Monitor Interval
UCI: multiwan.wan.health_interval
Opt: health_interval
Sets the period to check the health status of the interface. The
Health Monitor interval will be used for:
interface state checks
Ping interval
Signal strength checks
Web: Health Monitor ICMP Host(s)
UCI: multiwan.wan.icmp_hosts
Opt: icmp_hosts
Sends health ICMPs to configured value DNS servers by default.
Configure to any address.
Disable
Disables the option.
DNS servers
DNS IP addresses will be used.
WAN Gateway
Gateway IP address will be used.
Custom
Ability to provide IP address. Multiple
pings targets can be entered, comma
separated. Pings to both must fail for
health check to fail. Example:
option icmp_hosts ‘1.1.1.1,2.2.2.2’
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.
The 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.
