I'm just trying to have full functionality and now I have the time to figure these things out. My PC has it's own firewall too. Anyway, I enabled IPv6 DMZ towards the router and turned the Asus firewall on. I think it should be good now.
Alright, I didn't know that but when I put it in Passthrough IPv6 stops working entirely.
Edit: I think passthrough started working after turning IPv6 off and on and rebooting the modem. Idk, I was just trying some random things and noticed IPv6 clients were connected. So I checked my settings...
Hey,
The fix for this is probably simple but I can't figure it out. I've hooked up the Asus router to my ISP modem with DMZ enabled towards the router.
When I turn off the IPv6 firewall in the Asus settings, IPv6 works fine. When it's turned on it stops working. I tried opening port 546 UDP...
