When creating a PPPoE group, VLANs may be used rather than physical
interfaces to connect multiple modems to pfSense. This makes sense
particularly in larger setups where it is neither practical nor
necessary to install and allocate a physical NIC into pfSense for every
This approach requires creating the necessary VLAN interfaces in pfSense
and selecting those as member interfaces when creating the PPPOE
connection in PPPs.
Changes made on the PPPs page do not take effect until Apply
Changes is clicked on the interface configuration page, e.g.
Interfaces > WAN. Therefore, when making changes to PPPs, go
first to Interfaces > WAN and click Save. Make changes on
PPPs and click Save there, then go back to Interfaces >
WAN and click Apply Changes.
