How to setup port forwarding in Router

[mepi0011 (Pierre M.)]

Hi,

I was looking exactly for this solution / explanation!

Portforwarding FritzBox > Ipfire > NAS

It works!! In the Fritzbox, it’s no exposed host necessary. I just set TCP, external port 10021 to internal port 21 → forwarding to IPfire red (192.168.178.250). In IPfire this is my current configuration: [Screenshot_2021-03-10 12_48_54] When I ping :10021 the port is open now! Important to know is the note of Steven X: set no source-port Thank you for support.
