For those of you using PPPOE do you have a PPPOE server at each tower or just at the office/Dc?
If at the Office/Dc how do you bridge back? do you create L2tp tunnels or EoIP tunnels?
We have our PPPoE box back at the office - everything is hauled back there via VLANs. If you can’t drag plain ethernet over, however, I think that most encapsulations like L2TP would get the job done.
