Ignore all running iptables rules matching one or more provided
Ruby regexes. The regexes are compared against both the jump and chain
options of the running rules and excluded from the synchronization
comparison against the new rules. Do not include the beginning and ending
slashes in your regular expressions.
NOTE: If a rule has been added or removed, this setting ignored and
iptables will be restarted! If you have services which are
affected by this, make sure that they subscribe to Service and/or Service as
appropriate.
Examples: # Preserve all rules whose jump or chain begins with the word
'foo' ignore => '^foo'
# Preserve all rules whose jump or chain begins with the word 'foo'
or # ends with the word 'bar' ignore =>
['^foo','bar$']
