Port forwarding on a Yamaha NVR500 for SSH

networking

After we setup our office internet, I originally wanted to accept port forwarding from the outside world for SSH to a machine on our internal network.

Unfortunately, my Japanese is not good and neither is Google Translate when it comes to translating technical stuff. Luckily, with the help of my Japanese colleagues and some guess work, I followed some of the settings on this page here: http://www.obenri.com/_nvr500/remote_connection.html and was able to setup port forwarding into the router. I also had to follow the settings on this page http://cmf.ohtanz.com/blog/archives/44 to ensure the port 22 was forwarding to the correct local IP address.

In the example in the site, it’s taking the internal port forwarding of 45674 to port 80 for an HTTP request. I have my SSH port open on the machine to standard 22, and the rest of the work is done by the NVR500.

If you follow the section on the page under “SSHで直接ログインする”, the instructions should be pretty straight forward, even if your Japanese is not very good… like mine.
