i use rb20011ax2n,eth1=wan ethr2=hotspot ethr3=pppoe,i have bridged them using a port network switch so that i use one outdoor AP,how best can i avoid using the 5 port switch and merge them directly to the AP
As for me, I use both but on different routers
My PPPOE server connects to the clients and my Hotspot server between my border router and PPPOE server
The purpose of my PPPOE is to provide authenticated IP addresses to clients, Clients may be connected to the wireless network but without PPPOE-IP address they cannot do anything meaningful. Another reason is for traffic accounting. PPPOE authenticated users can access local servers freely but once they try to go out of the network (internet) they will be passed to the hotspot server.
this has really helped me to work with users using their IP addresses since it is PPPOE assigned.
Having PPPOE and Hotspot on the same interface does not make much sence and introduces security vulnerabilities.
