Q: Using Python sockets on LAN and isolating from WAN I have a quick question that I've been wondering about ever since I started socket programming in Python. I'm working on a server/client chat system for sending messages between computers connected to my LAN. My question is: is my LAN completely isolated from the WAN or does it have some kind of connection to it? and if so, how do I isolate my network?
the computers are connected to an all in one router/modem via ethernet cable. Also, the computer which will be running the server has another wireless connection to the internet (connected to the same modem/router but wirelessly)
I hope this makes sense, thanks for reading.
I want all traffic on my LAN to stay private and isolated so only computers in my home network can connect to the server.
