I have a issue with the new superhub 4 regarding port forwarding and using DMZ,
I have everything setup exactly the same as the superhub3 but it just doesn't forward the ports. I have tried multiple devices and now I have now external access using my new ip address. it seems the SH4 is lacking information like subnet and gateway details too.
also getting higher wifi speeds that 600mps seems impossible
I had the same problem. Virgin blamed my phone and laptop but i got a netgear nighthawk router and they get 900mbs now. 10gb ports or even 2.5gb would be the only way to get the Sam knows speed. I wanted to get my own modem and virgin said no. I tried a switch with 2 10gb ports to try linking 2 1gb lines to it and the sh4 wouldn't support that too
Yes - I have the same port forwarding issue although sometimes it does work so it seems hit and miss. I have port forwards set up for security cameras and they sometimes work in the morning then when I check 5 minutes later they are no longer working. My external IP can still be pinged and the port checks show that thy are open. I have static IPs for the target boxes and these are OK - its just the forwarding that works one minute and not the next - really odd!
