OpenWRT router – 3. Another problem

Once I’m testing this router(GL.iNET GL-B1300) flashed, PPPoE protocol on WAN interface fails to connect to the internet. I had no problem with pfsense for PPPoE. I can’t understand why this OpenWRT router won’t let me. I’ve already “fiddle” with MTU, that didn’t help.

So now I’m stuck in double NAT. Is it a problem? Not really, since I don’t host anything to the public. Even if I do, probably I can use port forwarding configured on Home Hub 3000 to my OpenWRT router. In fact, using HH3000 might be better for the internet speed because of a SFP media converter(TP-LINK MC220L). This one can only convert 1Gbps while Bell’s SFP module is 2.5Gbps, then it will decrease my internet speed as explained in this comment. 2.5Gbps SFP media converters are just way too expensive. Changing WAN configuration from PPPoE to DHCP might be annoying if my family members have to doas well. Not being able to configure WAN PPPoE protocol might be not that bad.

I just don’t want to see HH3000. That’s the problem but I will leave it.
