Apu Pfsense + ISP router
Im asking for a suitable set up to use apu pfsense 2.4.4 box with a ZTE router provided by my ISP. I do not have the admin account in my fiber ISP router and cannot configure it in bridge mode. Probably the right set up is to connect the WAN interface in the pfsense box to the LAN interface in the ISP router and use the FW rules to manage the traffic, but i would prefer to separate traffic with VLANs or address routing and then manage it with FW rules. Do not use the same network segment as the ISP router. And use the box for NAT,DHCP,etc.
You can do whatever you want on the inside/LAN.
On the outside/WAN you have to do whatever is compatible with what the ISP has provisioned and provided.
pfSense isn't able to change that.
