Hi
I’m new in the Mikrotik world and I want to know how mix three DSL lines and make the forth used for upload only.
Thanks
Are all 4 connections to the same ISP connection or are they different and when you say you would like the 4th one for upload only do you mean initiation uploads from your router or all egreess traffic is to go out ether 4. if it is the latter it will cause issues with things like tunnels and ssh connections as the traffic is not going out the same place it came in.
