Hi, I'm trying to restart my AE. It kept giving me error 6751 or something and asked to check the connection. Anyway, now it is somehow allowing me to set it up again. I'm not sure on this setting, it says "the AE is set up to allow configuration over the Ethernet WAN port, which decreases network security." Do I allow set up over WAN, or not? Thanks a lot, I appreciate any answers.
