Why can't I ping my MAC mini on my LAN?

I've been trying for hours to ping and ssh into my MAC from a windows machine on my LAN with zero success. I'm experienced troubleshooting network problems and this is baffling me.

Setup:

Mac mini with Sierra 10.12.3

connected wirelessly
firewall OFF
Remote Login enabled for all users
rebooted multiple times

Windows 8.1 Enterprise

connected by wire

firewall OFF

rebooted multiple times

Windows 10 PC

connected wirelessly

firewall ON

Router: Asus RT-N12D1

firewall OFF

latest firmware

rebooted multiple times

What doesn't work:

Neither Windows PC can ping Mac, or start SSH session

What I works:

Windows PCs can ping: Google, Router, Other windows PC on the LAN

Mac Can ping: Google, Router, Both Windows PCs on the LAN

What I have tried:

Rebooting everything

Switching the mac to wired connection and rebooting

Renewing DHCP on all computers

Turning on the mac firewall and making sure stealth mode is turned off and that remote login is turned on

Double-checking IP address with MAC addresses on the mac

Ran a port scan on the mac (Open: 22, ssh)

I am stuck. Any ideas?

Mac mini, macOS Sierra (10.12.3)

I was able to partially get around this by turning on IPV6 on my mac and on my router. Now I can ping and ssh to the mac, but only using the ipv6 address.
