I'm configuring a server that sits behind a reverse proxy, in which an SSH tunnel is configured to the server due to firewall restrictions.
The reverse proxy is managed by someone else and I would like to control the tunnel from the server side by enabling reverse SSH tunnel.
I did some research and it seems very simple as enabling
Gatewayports=yes on the sshd configuration of the reverse proxy.
I see that by default this option is set to false, which is probably for a good reason.
Is there any critical vulnerabilities or any other issue that I should consider before enabling reverse SSH tunnel on the reverse proxy?
