My equipment: NVG589 and Netgear WNDR4500 (NVG589 ip pass through set up / WNDR4500 handles routing)
First of all I know that ATT current IPv6 can be a headache and I am no expert about it either. When I got on the power tier months ago some things with IPv6 did not fuction right on my network, so I just totally disabled it on both the modem and router. I did not want to take the time to mess with it.
Yesterday I decided to dive into it to see what I could get. I turned IPv6 back on for the 589 and then set the 4500 IPv6 to auto detect. It pulled an IPv6 address and some other info. Then i hit the web to run some of the tests. Just like months ago IPv6 websites time out but anything having to do with "Is your ISP ready" passed the tests.I know that most likely means that my network side is not correct with settings.
I start playing around with individual IPv6 settings in the router. Such as 6to4, manual, dhcp, and auto config. Still, being no expert, not everything would work right. Well.... my router has a IPv6 mode that is simply called Pass-through. I enabled it, but when enabled it just says that it is enabled and there is no other info displayed. No IPv6 adresses or anything.
But........ This allows everything to work. All IPv6 internet tests pass with all devices on my network (computers, phones, xboxs.....) All devices show having both IPv4 and IPv6 addresses from the IPv6 test site. Comcast speedtest now performs both Ipv4 and IPv6 speedtests.
Now to my concern..... I don't know what the pass-through is actually doing and if it is safe. I know there is concerns with IPv6 and firewalling as it does not work the same as nat for IPv4 (again no expert). The only info that Netgear gives as to the pass-through mode is this:
In pass-through mode, the router works as a Layer 2 Ethernet switch with two ports (LAN and WAN Ethernet ports) for IPv6 packets. The router does not process any IPv6 header packets.
I hope this all makes since to everyone. I just need some input as to use it this way or not. I don't have to have IPv6. Sometimes I just like learning new things.
Thanks!!
