I have a similar problem (same infrastructure and same symptoms) but with random occurrence. Ssh session hangs randomly, usually before the login prompt is shown), sometimes a bit later, sometimes after few days. I have MTU 1500 on all interfaces taking part in communication. Ping of any size works and as far as I tested, HTTP communication too, but there are problems with HTTPS. -- Best regards, Seweryn Niemiec
