UniFi Network With a Non UniFi Firewall (pfSense With Layer 3 Adoption)
UniFi Network With a Non UniFi Firewall is a pretty common practice in the networking field. Many MSP companies will even recommend their client to use UniFi access points and switches but in some cases, they will recommend some other vendor firewall like pfSense or even Edgerouter.
In this UniFi Network With a Non UniFi Firewall we are under the assumption you already have a UniFi controller in a remote or cloud location already up and running with port forwarding enabled already. Without this preliminary step, you wont be able to accept incoming adoption requests from your UniFi devices.
Another assumption made in this UniFi Network With a Non UniFi Firewall video is that you will not be using a single flat network (not recommended) and you will be segregating your network into Vlans. Traffic between Vlans should be firewalled properly!
This UniFi Network With a Non UniFi Firewall practice comes with a very good reason in some cases and in other cases going full UniFi (AP's, Switches, Gateway) makes prefect sense. It really depends on the deployment and the network needs.
Some of us home lab geeks just prefer pfsense and so deploying UniFi Network With a Non UniFi Firewall is just a matter of preference. I personally LOVE pfsense and going in this UniFi Network With a Non UniFi Firewall direction with a pfsense firewall is definitely a sweet spot. You just cannot go wrong with pfSense!
In this video we are to learn how to actually go about creating a UniFi Network With a Non UniFi Firewall. this means we will create vlans, dhcp, firewall rules in pfsense and even set whatever is needed to make layer 3 adoption easy and almost automatic if you are using an offsite UniFi controller.
