Metric
integer
Used as a sorting measure. If a packet about to be routed fits two
rules, the one with the higher metric is applied.
Additional note on Target & Netmask: You can define a rule that applies to a single IP like this: Target - some IP;
Netmask - 255.255.255.255. Furthermore you can define a rule that applies to a segment of IPs like this: Target – an IP
that STARTS the segment; Netmask – Netmask that defines how large the segment is. E.g.:
192.168.55.161
255.255.255.255
Only applies to 192.168.55.161
