Issues setting up transparent firewall
-
So I am setting up pfsense in bridge mode as a transparent firewall, but I am having issues with interface setup. So I havec Routers, an att router in ip passthrough will firewall disables, and my ubiquity edge router lite. I have the wan port of pfsense connected to att, and the kan connected to my edge router. The wan interface is set to none for the IP type, and so is the wan. Lan and wan ports are added to a bridge. I had an issue setting up the bridge interface, the art router is on a .2.xxx subnet, and my network is on a .1.xxx subnet. So on the bridge interface I set its IP on the .1.xxx subnet, and then enter the att router in the upstream router IP field, which is in the .2.xxx subnet it errors saying they have to be in the same subnet. Why is this, am I missing something? Do I just need to change my att router IP and everything will work?

Is the ERL also routing and NAT'ing?
If the AT&T routing has a 192.168.2.X sibnet on it's LAN then it is not in bridge/modem mode. The subnet between the AT&T LAN and the ERL WAN and everything on it, including pfSense, will be 192.168.2.X.
So probably you need to set the bridge interface to the .2.X subnet. Then you will be able to add the AT&T router as a gateway.
A diagram might help a lot here.
