view filter use in Conn. Tracker

I want to filter only these connections by argument Dst.Address/Port or Src.Address/Port to show in my Conn. Tracking window. But although I can pick the argument I cannot find which format is accepted in this CT filter?

I tried xxx.xxx.xxx.xxx:ppp where xxx.xxx.xxx.xxx is the IP and ppp is the port number.
I tried xxx.xxx.xxx.xxx;ppp
I tried xxx.xxx.xxx.xxx-ppp
I tried xxx.xxx.xxx.xxx/ppp
I tried xxx.xxx.xxx.xxx,ppp
I tried xxx.xxx.xxx.xxx.ppp
I tried xxx.xxx.xxx.xxx+ppp

Nothing… :frowning:

And this while the unfiltered window shows xxx.xxx.xxx.xxx:ppp (or pppp, pp, ppppp)

Any suggestions?
