That is an old screenshot from earlier this year, sorry. I have attached the latest and pretty much original config. As you can see ether 5 is a different server(quantar) no problems there all the problems are on ether 2,3,4 which are bridged. Thanks for having a look UPDATE: looks like lease time is 2hours? No Idea about that home network and suggestions?
