Sporadic failures of ssh into PC through 5268AC gateway
I have my gateway configured to open a pinhole for port 22137 and forward it to port 22 on a Linux PC on my network. Sometimes it works, sometimes the attempt times out. If I keep trying, eventually it works. It's as if the gateway had a rule something like "only allow one incoming connection per minute". If I ssh from another computer on my LAN, it always works, so it seems like the problem has to be with the gateway. This problem started after a much older model of gateway was replaced.
