I have recently joined a company and have been tasked with coverting their iptables firewall to PFSense.
I am looking for a bit of help with coverting this over…eth0 and eth1 have the same IP address on our firewall, with different subnet masks.
eth0 is physically connected directly to a cable modem, whereas eth1 is the interface for the DMZ which has
INET_IP='x.x.x.1' <------ 255.255.255.255, public IP
DMZ_IP="x.x.x.1" <----- 255.255.255.0, public IP
This rule allows traffic to the internet
$IPTABLES -A FORWARD -i $DMZ_IFACE -j ACCEPT
Can I replicate this setup in PFSense? I have tried adding these addresses to WAN and OPT1, but PFSense complains that the address is in use by another interface.
