I have used pfSence with Comcast Internet in the past with my own modem. However, it has always been with a DHCP WAN. I now have Comcast Buisness with an CBR-T (CGA4131COM) Gateway/Router and one Static WAN IP.
I have my assigned Static WAN IP as well as my WAN Subnet. My understanding is that within the pfSence WAN interface. I need to change from DHCP to Static and input my Static IP into the WAN IP field. Then input my Static WAN IP Subnet into the Subnet field.
Next I believe I would have to call Comcast Business Support to have them put the CBR-T into a kind of Bridge mode. Is this it? Is there anything I'm missing to get the pfSence device connected?
Also, am I able to keep the stock LAN IP 10.1.10.0 across both devices.
e.g. CBR-T (10.1.10.1) -> pfSence (10.1.10.2) -> LAN PC (10.1.10.xx)
