[mosh-users] Which ports to open on the client side?

[Alan Schmitt]

Hello,

I'm trying to run mosh in an environment where there is a firewall, so
I'm trying to see what ports need to be open, and in what directions,
for things to work. I have launched mosh-server on my server, and it
does seem to be receiving the initial packet (I turned debugging on):

Server now attached to client at ****:49661

I then get a lot of messages with Sent, until a timeout occurs. On the
client side (behind the firewall), I get a blue bar telling me it has
not received any paquet from the server.

What worries me is the port number at the end, which is very different
from the one I gave on the command line. When I launch mosh-client, I
also don't see a way to specify the port on which it will receive the
answer. So is there a way to specify which ports to use on the client
side?

Don't hesitate to tell me if my question is not clear, I don't know much
about UDP networking.

Thanks,

Alan
