I know unix scripting (shell, python, etc), and have some grasp of the theoretical underpinnings of TCP/IP (I have read
Kurose, James F.; Ross, Keith W. - Computer networking : a top-down approach). But I have almost no skills in managing my own home network (things like
route in macOS,
iptables in Linux). How should I start learning about practical network administration?
Things I am interested in being able to do:
- Route traffic based on the destination IP, or the application issuing the request
- Create LAN-like internal networks between machines connected by the internet, via, e.g., Wireguard
- Prioritize the speed of various devices connected to my home router
- Limit speed of specific ports
- Create a guest Wi-Fi network, with limited speed and rudimentary analytics
- Create a local Wi-Fi network that is not connected to the internet
- Create chained VPNs (machine A to machine B then to machine C)
- Use the Wireguard VPN on a server without messing up its SSH clients
The OSes I use are Ubuntu, and macOS.
PS: If this question is not on-topic here, I'd appreciate some tips on the forums to ask it on.
