I am trying to troubleshoot some NAT Type issues I am having with my PS4. I want to avoid creating specific port forwards, since I think they should be unnecessary with UPnP. While poking around in the latest Toastman build, I found a few settings (Advanced / Firewall) I was curious about. Does anyone have some info on these? I did some Googleing and couldn't get much about what they would directly impact, etc. Specifically, I am wondering what impacts the multicast and NAT settings would have? Is there a chance that some of the multicast settings may help with the NAT issues I am having?
