# install mosh
yum install -y epel-release
yum install -y mosh

# add firewall rules
firewall-cmd --zone=public --permanent --add-port=60000-61000/udp
firewall-cmd --reload

Thanks! iptables didn't work but your firewall-cmd did the trick 👍

For anyone else who's new to Mosh, what you do next is launch Mosh on the client. The client will start the Mosh server on the remote machine. E.g.:
mosh -p 60000 --ssh 'ssh -F ~/.ssh/config -i ~/ssh.key johndoe@123.45.678.90' johndoe@123.45.678.90

Mosh shouldn't need the --ssh flag for subsequent connections:
mosh -p 60000 johndoe@123.45.678.90
