Hello, Most of the internet providers in Germany are only using a public ipv6 addrees and are tunneling all the ipv4 traffic through a provider gateway (AFTR). (Carrier NAT IPv4.) In the TP-Link route

My german ISP does only provide internect connection via dual stack (DS-Lite). My attempts to get the ER605 working with an DrayTek modem weren't succesfull. Does the ER605 support internet connection
