# Compiled for iptables (any version)
#
# 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

# heartbeat_cluster_1_d:Policy:7: error: Can not build rule using dynamic interface 'eth0' of the object 'linux-2-d' because its address in unknown.
