fwbuilder/test/ipt/firewall34.fw.orig
Vadim Kurland f366e2dc66 * PolicyCompiler_PrintRule.cpp (_printOptionalGlobalRules): SF bug 
3178186 "Add ND/NS allow rules for the FORWARD chain". Rules that are
added automatically to ipv6 Linux firewall to permit neighbor discovery
packets should be also added to the FORWARD chain if the firewall is
a bridge.
