If no address is acquired the field displays not available. The transition from ipv4 to ipv6 that is currently underway creates a big problem for most vpn services.

What is ipv6 passthrough. With ipv6 the customer should get a routed prefix 48 52 56 60 or 64 for example using dhcpv6 pd which doesnt require pass through or bridging. Most vpns have been slow to accommodate this transition to ipv6 and update their server networks. All ipv6 traffic over wired ethernet works fine. Pas through seemed to work as it effectively also disabled ipv6. Click status to check whether you have successfully set up an ipv6 connection. Ipv6 will eventually replace ipv4.
Click save and skip to step 6. My understanding is that passthrough means that the router does not look at the ipv6 header and operates as a l2 switch where it simply forwards the packet. The number after the slash is the length of the prefix which is also indicated by the underline under the ipv6 address. If pass through is needed for working ipv6 then i would say the isp has done something wrong. Ok i discoverred that pass through actually does not work either and the issue is actually an ipv6 bug. Fill in address prefix provided by your isp and click save.
Asus has both an ipv4 and ipv6 firewall that is enabled by default. All ipv6 traffic over wifi is blocked and doesnt even reach the ea7500 router. Wan automatic ip select passthrough as ipv6 connection type wan static ip select static static ipv6 as ipv6 connection type native profile was selected. The following figure is an example of a successful pppoe. Ipv4 is the current industry standard in tcpip networks today and is the de facto internet routing protocol. For this tutorial i will choose the native as my preferred ipv6 connection type.
Ipv6 increases the ip address size from 32 bits to 128 bits to support more levels of addressing hierarchy. Windows users are recommended to choose from the first two types. This field shows the ipv6 address that is acquired for the routers wan or internet interface. I think ipv6 pass through means there is a bridge between the wan and the single lan. Routers ipv6 address on wan. Of course upgrading servers to support ipv6 is an expensive and difficult fix.
