My phone company gave me a new modem. It has its wifi and ethernet ports
on the same ip lan. I have one of its ethernet ports hooked to a switch.
I noticed that a wired machine on the switch can't seem to reach a host
on wifi until I "warm up" its arp cache by contacting it from the wifi
host first. I hope that made sense. Is this an issue for anyone else?
Do I need to search the modem's menus to tell it to forward arp data
between the two segments of the lan? I don't see something obvious. Is
this considered an security issue to avoid spoofing from war drivers or
something?
