In order to protect my local network from an attack on an self hosted server (although it's probably unnecessary), I would like to block all outgoing traffic to the LAN.

At first this seems easy, as blocking the private IP ranges should do the trick, but my ISP provides my router with a public IPv6 prefix as well. Every device in the network gets an IP from that public range (for port forwarding) ...

I have an open-ssh server setup on Linux Mint with ssh keys and a ~/.ssh/config file on my Mac where I do most of my workflow.

However, the same command when not on the LAN works as expected, allowing me to make multiple ssh connections simultaneously.
