Enable ONLY ssh access on one interface?

[Jon Lachmann]

Hello!

I am planning on setting up a ProxMox server in a co-location computer centre. The server will host various virtual machines and will have multiple network adapters.

I plan on running a pfSense virtual machine to get VPN access to an internal network from which I can reach the web interface and VNC to the virtual machines. However i would like to be able to log in via SSH to the server in the case of a malfunction of the VPN service. How can i open ONLY the ssh terminal on one of the configured interfaces?

If this is not yet possible i think that choosing which interface each different service is published against would be a great addition to this already great piece of software.

Best regards

Edit /etc/ssh/sshd_config - uncomment ListenAddress and set it to the IP you want it to work with. At least that's the case for standard Debian systems anyways... I've also restricted the Proxmox HTTP server to also listen only on certain IPs.
