-Find all firewall rules that match the given criteria. Expects a table with search criteria as only argument.

-
-The following keys in the args table are recognized:
-
- - table Match rules that are located within the given table
- - chain Match rules that are located within the given chain
- - target Match rules with the given target
- - protocol Match rules that match the given protocol, rules with protocol "all" are always matched
- - source Match rules with the given source, rules with source "0.0.0.0/0" are always matched
- - destination Match rules with the given destination, rules with destination "0.0.0.0/0" are always matched
- - inputif Match rules with the given input interface, rules with input interface "*" (=all) are always matched
- - outputif Match rules with the given output interface, rules with output interface "*" (=all) are always matched
- - flags Match rules that match the given flags, current supported values are "-f" (--fragment) and "!f" (! --fragment)
- - options Match rules containing all given options
-
-The return value is a list of tables representing the matched rules.
-Each rule table contains the following fields:
-
- - index The index number of the rule
- - table The table where the rule is located, can be one of "filter", "nat" or "mangle"
- - chain The chain where the rule is located, e.g. "INPUT" or "postrouting_wan"
- - target The rule target, e.g. "REJECT" or "DROP"
- - protocol The matching protocols, e.g. "all" or "tcp"
- - flags Special rule options ("--", "-f" or "!f")
- - inputif Input interface of the rule, e.g. "eth0.0" or "*" for all interfaces
- - outputif Output interface of the rule, e.g. "eth0.0" or "*" for all interfaces
- - source The source ip range, e.g. "0.0.0.0/0"
- - destination The destination ip range, e.g. "0.0.0.0/0"
- - options A list of specific options of the rule, e.g. { "reject-with", "tcp-reset" }
- - packets The number of packets matched by the rule
- - bytes The number of total bytes matched by the rule
