For some reason I have issues with Photoshop AI as it won't generate and pops with this error. As soon as I connect back to my isp modem it works fine.
So I have option in my modem to enable port forwarding
Should I enable it and disable upnp in R3 or disable port forwarding in modem and enable upnp in R3?
Of course I'll need to set R3 in wan with the port forwarding IP I'm given.
