Hi All,
Is the "correct" way to fix the Spoof Protection when attempting to bridge interfaces via Proxy ARP which contain hosts in the same subnet:
/etc/rc.d/iptables.nat
chmod 755 iptales.nat
Then in the file add the line:
iptables -F SPOOFING_PROTECTION
Then create static interface routes to each additional IP residing in DMZ.
This is for the situation when:
Public interface IP of firewall is in a subnet block
DMZ interface is a private (RFC1918) IP
Devices on DMZ have IPs in same subnet as firewall public interface.
