single object negation in "Inbound Interface" and "Outbound Interface" columns in compiler for iptables. * NATCompiler_pf.cpp (compile): see #2456 Added support for single object negation in "Interface" rule element of PF NAT rules. Now compiler can produce PF commands such as "nat on ! em0 ... " (for PF <4.7) or "match on ! em0 ..." (for PF >= 4.7) * Compiler.cpp (singleObjectNegation::processNext): moved rule processor that processes single object negation in any rule element to the base class Compiler.

# This firewall has two interfaces. Eth0 faces outside and has a dynamic address; eth1 faces inside.

# Policy includes basic rules to permit unrestricted outbound access and anti-spoofing rules. Access to the firewall is permitted only from internal network and only using SSH. The firewall uses one of the machines on internal network for DNS. Internal network is configured with address 192.168.1.0/255.255.255.0
