I remember having to do a lot of port forwarding to get certain things to work behind a nat. Certainly doable but beyond the competence of a non-expert.

Qatar used to share a single IPv4 address, which I found out when news articles started reporting that the entire country could no longer edit Wikipedia without an account, which at the time, was also restricted if your IP was banned from anonymous edits. If you didn't create an account prior to the ban, you were completely blocked from editing. https://en.wikipedia.org/wiki/User:82.148.97.69 https://en.wikipedia.org/wiki/User:82.148.97.69 https://techcrunch.com/2007/01/01/wikipedia-bans-qatar/ https://techcrunch.com/2007/01/01/wikipedia-bans-qatar/
- jjjjmoney 3y agoThis isn't entirely about static port-forwarding. As others have pointed out, STUN, VoIP, PASV, etc rely on deterministic NAT behavior to work. That is not always guaranteed, and often out of your control.
