This is an older router, but still flawed. So far it:
-Screws up IGMP (including Bonjour)
-Screws up AppleTalk AARP packets
-Has a completely broken RIP implementation
-WAN side flips out and doesn't pass traffic if you have a private range IP (in double NAT situations).
Thank you! I was able to successfully use this version and an AirTalk box connected to my Mac Plus 4mb (and printer not modem cable) to access a share in Mini vMac. The version of Mini vMac (running on Windows 10) I paid-for didn't have the functionality.
