[Discuss] Limit the number of ip addresses which can connect to a port

Yes. I want only one IP gets access to the service. However, I don't own
this application and I don't have the source code. That is why I can only
using firewall to handle it.
If there is no software capable to handle this, I am thinking about writing
a shell script to do it myself.
