Forward Port config

How to add local forward setting to my ssh config file?

I currently can do this: ssh 12.34.56.78 -L 8888:localhost:8000 And I can then open my local browser to localhost:8888 and see the app running in my server at 12.34.56.78:8000. I want to avoid having to type in that forward command and instead place that config in my ssh config file.

Remote Forward

Creating a ssh config for a reverse tunnel + local forward

The easiest way is probably to avoid the local forwarding, that appears unnecessary in your case, and leverage the ProxyJump directive, which lets you specify one or more jump proxies (i.e. one or more intermediate host(s) you connect to and from which you reach your target host).
