                ssh tunnel for ip forwarding
              
          
    Sometimes we want to access a locally available device from a external facing ip address. (e.g. Like a computer on a local lan network with a separate wireguard interface.)
We can do this by using a SSH tunnel
ssh user@remotehost -L localport:host_reachable_from_remote_host:remoteport
e.g.

    Wireguard and iptables restrictions for multiple users

If you don't know what Wireguard is, well, you should.
It's fast, easy to setup and highly configurable.
We will configure Wireguard for multiple users with various restrictions using iptables.
Assumptions

This should fit most setups (not mine though 😉)

                Using multiple github accounts with ssh keys
              
          
    Problem

I have two Github accounts: oanhnn (personal) and superman (for work).
I want to use both accounts on same computer (without typing password everytime, when doing git push or pull).
Solution

Use ssh keys and define host aliases in ssh config file (each alias for an account).
How to?


Generate ssh key pairs for accounts and add them to GitHub accounts.
