The wireless interface type in pfSense is for wifi hardware in pfSense itself which is not what you have.
Your access point should simply be connected to one of the LAN ports in the 2100. Devices that connect to the AP will just get an IP from pfSense in the LAN subnet. Later you may want to move those to a new subnet so you can filter between them but I would only attempt that after first making it work as part of LAN.
The pfSense WAN should be set to PPPoE but that can only work if the upstream device is bridging the PPPoE connection correctly.
@wifi75 non mancava nulla.
Avevo fatto tutto esattamente come hai suggerito tu, ma non c'era login.
Ho chiamato il provider il quale ha inizialmente detto che poteva essere un problema del mio router, così mi sono procurato un altro router ma neanche con questo c'era login.
Di conseguenza hanno aperto un ticket con OpenFiber, e alla fine è venuto fuori che quando hanno fatto l'allacciamento si sono dimenticati di attivare qualcosa, per cui non c'era possibilità di connettersi.
Io avevo dato per scontato che fosse un problema di configurazione perché dopo che OpenFiber ha fatto l'allacciamento ho chiesto espressamente se la linea dovesse essere attivata dal provider, ma mi hanno assicurato che "potevo già navigare!"
OK, can anyone advice what would be better to get TOPTON i7-1165G7 i211AT 6LAN or QOTOM Q575G6 i7-7500U i211AT 6LAN. I'm on PPPoE FTTP (UK). With current electricity prices I'm trying to find most efficent solution(without breaking the bank [ie. SG-6100 max]).
@akuma1x Yes it's easy enough to buy some secondhand/commodity hardware.
Anything you can find with enough network ports and an Atom C3XXX, or Intel i3/i5/i7 processors, or even some of the more recent fast Celeron and Xeon processors. Those are all good for a pfsense box. Try to stay away from the laptop-grade mobile processors, and the older Celeron J1900 stuff. Those are going to show their age and weaknesses quicker than the other ones.
HP and Dell made/make some good small form factor stuff. Just make sure you can add at least 1 multi-port INTEL network card in there and you'll be all set with a nice pfsense firewall box.
and more specific, this one's an i5 https://www.amazon.com/QOTOM-Q355G4-Factory-Firewall-Multi-Function-Appliance/dp/B06XNWLR3J/ref=sr_1_fkmr2_2?keywords=pfsense+firewall+black-boxes+i5&qid=1553882807&s=gateway&sr=8-2-fkmr2
This one is a much better choice!
I'm going to get up on my soap box here... keep in mind, you should try to support the pfsense open source project as much as you can. With the Qotom box you found, you're only about $60 away from the "official" Netgate SG-3100 box. I'm not trying to guilt you into a purchase, and I'm not saying you're going to get a better experience with name-brand or not, but being that close in price, I would send my money to Netgate and the firewall project itself.
At first his ISP thought he was going over his rated speed, but we traffic shaped and determined that was not the problem. His ISP now thinks it is the PPPoE Keep Alives not being recieved thus terminating his line. How would he got about mitigating this on the SG-1000?
