yes Fraser i know that it is not quite optimal but my ps4 is in the basement. with the xr300 i sometimes have problems with the wifi on the upper floors so i don't know how it will work with the r2. that's why I want to give it a try. I can do without the few Mbit and if there are major updates I will increase the bandwidth on the switch for the r2. I'll test it like this if it's nothing I'll just leave the switch off and connect the xr300 to the r2.
ok fraser thank you very much. I have now got an open nat for both options. it felt like it was going better with pppoe on the xr. could of course also be due to the servers. think it would change again like that otherwise would have believed the Fritz box and xr as exposed host.
