How to Forward Interface Traffics?

i’m using Router Os 5
i have a interface with ADSL Internet access and another Interface with WiFi Users
I want to forward My WiFi Interface Traffics to My ADSL Interface (without any ip/route or ip/firewall/nat) (Regardless of IP Address)
is there any way to forward all of an interface to another ?

You can bridge interfaces together but then the Mikrotik unit might be doing little more than acting as a switch. Further details of your application would help.
