If you need to find something on your network, get your IP easily, or test your system’s ports WhatIP has you covered:


Nice one! (At least 10 chars…)

Let’s assume that I have a service S running on the L5 for local use. Most of the time I external stations not to be able to see anything of S, for protection. Sometimes I work on another system like a desktop computer and want to access S temporarily.

How could I open access to S for external access temporarily and close access afterwards?

Some services could be configured like that which may need a restart of S. It would be nice to have service independent mechanism.

Could it be done with nftables? Any other proposals?
