On the Behringer UMC (I've got the 404), you will only hear the monitor through the headphone jack on the front of the unit. For some reason, monitoring does not come through the main outputs on the back of the unit. You can hear what is coming from the computer, but not the monitor mix of the input and the computer output (don't know why that is).

On my system, I just plugged a headphone amp into the headphone connection on the Behringer unit. Then I run a pair of headphones out one of the headphone amp outputs and my powered speakers through another headphone amp output and that way I can hear the mix through speakers.

Mine is new, so I've not discovered all possibilities, but this works for me.
