Why can't linux connect nat?

[HingxoGamchu]

I am currently experiencing issues connecting to the internet on a NAT network while using a Linux system. Despite trying several troubleshooting steps, I have not been able to resolve the issue. Could you please provide detailed guidance on how to diagnose and fix internet connectivity problems in this specific scenario? Additionally, could you suggest any common configurations or settings that might need to be checked or adjusted to ensure a stable connection on a NAT network in a Linux environment? Any commands, logs, or tools that can help identify the root cause would be greatly appreciated.

The linux community really appreciates it! Port forwarding is a big thing that made me go back to windows (unfortunately). Perhaps this is what will bring me e-chat back to Linux full time
