algorithm used to decide which interfaces of the host or firewall
object to use in a rule when this host or firewall object is found
in source or destination.
bug (no #): policy compiler for iptables did not handle correctly
rules where a host that has multiple addresses was a single object
in a rule element and had negation.
* NATCompiler_ipt.cpp (singleObjectNegation::processNext): added
support for single object negation in OSrc and ODst in NAT rules.
This provides for more compact iptables script in the often used
case where single object is used with negation in these elements
of a NAT rule. Other improvements in handling NAT rules with
negation.
