I was following this hardening guide here and had some questions regarding configuration of PPPOE
My modem is already in bridge mode so as far as I can tell it basically just translates the signals to something my router can understand, and that’s it. It doesn’t have a presence on my LAN, can’t hit it via basic NMAP scan. I’m not sure if the ISP can take it out of bridge mode, but as for right now I believe I have I already done what the step above suggests. As in any firmware exploits shouldn’t affect me at this point. Am I correct in this assumption?
Also the article suggests that this for cable or DSL providers, but I’ve read that PPPOE is largely for DSL, and I don’t think my ISP provides it for cable connections.
