I am looking for some advice from the group about the best way to put
pfSense in my environment so that it can filter all traffic. The cable
provider that I use has given me a /29 of static IP address and one of
those addresses is assigned to the cable modem. When I asked about
putting the modem into bridging mode I found out that their idea of
bridging is to disable the firewall and DHCP service on the modem. So
this is what I have come up with so far.
Cable Modem: 70.70.70.94
pfSense WAN: 70.70.70.93 (also my NAT address for the LAN)
pfSense LAN: 10.100.100.1/24
pfSense OPT1: bridged to WAN interface, no IP address
The OPT1 interface is connected to a switch that has the other devices
with the remaining IP address in the 70.70.70.89/29 space and I have the
firewall rules for this space on the WAN interface. It seems to work but
I am wondering if I am using the bridging feature correctly. Any thoughts?
Thanks,
Tim
