If you don't have control over the gatewat router and don't want to add
another layer of routing, then you cannot solve this. But as a
workaround for better coping with ssh through a bufferbloated network
you can use mosh both at the server end and on your client systems.
I wasn't able to do much with the network, but using mosh now helps a lot.
Thanks, Jonas!
