Hello,
I'd like to suggest adding a small note field to the port forwarding menu, where you could for example note which port works for which of your services. Having many of them and having to use a different external and internal port sometimes takes a while to remember which port was meant for which service.
/off topic, on a sidenote I have to praise the performance / service of Air. I came over from PIA after Kape's takeover and would never look back. Speed wise, connectivity wise and especially for port forwarding needs. Will stay a good while.
Have a nice day!
