Configuring VLANs on pfSense

Intro: In this article I will go over how to configure routing between multiple VLANs by using our pfSense router and a switch that supports 802.1Q.

The uplink port on the switch side connecting to our pfSense router will be set to tag all the traffic using the 802.1Q protocol. This configuration is known as a router on...

At this point in time we have covered the majority of the basic OSPF configuration and I will now move to the informational commands. The first useful command is the “show ip protocols” which tells us what routing protocols are currently...
