IPv6 disables hardware NAT

  • Hi

    I am using the ISP www.hiper.dk that provides me with a gigabit fiber connection where I have connected the amplifiHD direct to the fiber converter supplied by the ISP.

    They provide both IPv4 and IPv6 (as DHCP6). When I only have IPv4 enabled and enables hardware NAT I can max out my connection (above 900 megabits) but if I enable IPv6 the amplifi HD only delivers speeds (around 250 megabits) that seems similar to the IPv4 performance with hardware NAT disabled (but it is still marked as enabled).

    The hardware ID of my router is 19, the software is 3.3.0

  • After some debugging support answered this to me:

    I have received a response from the development team.

    In HD model, IPv6 is slower than IPv4. In Alien, they provide wired speeds equally fast. This is the reason, wired speeds decrease when IPv6 is enabled. For better speeds, please use AmpliFi HD in IPv4 and disable IPv6.

    Hope that's helpful. If you have any other questions, please let us know!
