Forwarding a port to a website

[Hakolb]

Is there a way to make a port on my router so when someone tries to connect to it, he is redirected to a specific website?

For example if someone writes "myip:12345", he is redirect to www.google.com

No, unless you put some additional equipment behind your router (or your router can run custom firmware).

Just don't open the port on your router. That is far better than causing unnecessary extra traffic for another website.
