I would like to use mosh in order to keep some ssh connexion even if close my
mosh is installed on a jail and ssh is listen on port 4243
I tried, from my laptop
`mosh --port 60000 --ssh "ssh -t -t -p4243" -- host ssh -t -t jail
It does not work and the error is:
mosh did not make a successful connection to ww.xx.yy.zz:60000.
Please verify that UDP port 60000 is not firewalled and can reach the server.
(By default, mosh uses a UDP port between 60000 and 61000. The -p option
selects a specific UDP port number.)
[mosh is exiting.]```
Looks like a `pf` problem, I need to open the 60000:61000 port range.
So I read the pf man page and saw that range are define with a colom:
means ‘all ports ≥ 2000 and ≤ 2004’, hence ports 2000,
2001, 2002, 2003 and 2004.```
So I defined:
`mosh_port = 60000:61000`
and the rule:
But nothing works.
So I need your help or advices to configure, I suppose, `pf` to make mosh
working for contacting my jails.
Thanks in advance
