1) It's not recommended that you run static IPs and DHCP alongside PPPoE for security reasons, HOWEVER I have an existing WISP with Trango Broadband equipment. Each AP and each SU/Client has a static (private) IP, if I have these on a PPPoE interface, I lose visibility to them, though the PPPoE clients (consumer routers) beyond work fine. Those static addresses don't need to get out to the internet, just be visible on the network for troubleshooting, snmp access, FW updates, etc.
2) We run NAT on our core router with three vlans, one for each of the geographical areas we serve. These addresses are spread among many towers and APs, and are hand entered static addresses in the customer routers. To migrate over to PPPoE, I need to allow this NAT pool to run alongside the PPPoE, and still get out to the internet while we go through the tedious process of changing over each individual subscriber's router to PPPoE. We provide a router with our service and we used to do a lot more hand-holding, so we have remote management to almost all the subscriber routers. Any ideas how I can migrate?
3) I'm confused as to how the switch functions relate to the PPPoE and routing functions. How do I assign a PPPoE service to a specific VLAN? Our network is switched at this time, but we have managed switches everywhere. The original idea was to have a core mikrotik device routing our network through individual VLANs from each AP, instead of one vlan being shared by many APs and towers.
I'm sure I'll ask more questions as the come up. Thanks for the help!
