Do you see any performance issues with having to use pppoe there with gigabit rates?
I ask because some devices, even my home Fortigate unit tend to have performance issues because of pppd having to run in userland to shuffle packets then, and has been an issue in various vendor devices over time. My fortigate is large enough (100D) I don't see issues with my 150mbps bonded dsl here, but a buddy with one step down in a fortigate (90D) said he had to replace it on the same service. I'd imagine if I could get gigabit and use it, I'd need a new box.
One thing I really liked about cable modems, is they figured out how to handle security outside your client, so no pppoe weirdness at the modem or firewall. I can't believe CL still forces that even on their fiber...
