I have the problem, that for one specific client, the tunnel builds correctly and I can connect from the server, but if a larger quantity (say a few kb) is sent, the connection stalls. I can then succesfully open a new connection (ssh), and that will work fine (while the other is stalled) until I also transfer the few kB and that one also stalls.
From the doc and forum I think I hit the problem that "path MTU discovery is broken". And I am currently trying to fix with
server.conf:
fragment 1300
mssfix
client.conf:
fragment 1300
(trying these fixes on a remote system which always stalls is difficult...).
Currently, I see this problem only on one client. Two other remote clients are working fine without the fragment option.
I try to understand, what makes that one link different, and what "path MTU discovery is broken" really means. Could you point me to relevant docs?
In your experience, is this fragment option often needed?
Thanks Phil
