USG seems to be more consumer friendly... also i m not using all ports on the edge R X so i can remove it from the modem replace it through the usg for pppoe connections and use the edgerx later in the datapath. Its a test and try to find the best solutions for my setup.
"Modem ist just a modem" Its a Speedport 221 works fine with Airport Extreme Port Forward Handling but not with the EdgeRouter - so from my Point of View the Edgerouter is the trouble maker...
There are so many posts out there with people having issues with the edgerouter pf ... so i think the truth is somewhere between.
