iPv6 over Repeater on ASUS TM-1900/AC68U

[Avi Shah]

I'm trying to get the ASUS Router (RT-AC68U/TM-1900) that repeats my main wifi SSID (Netgear R8000) to enable iPv6 but I cannot get it to work on the merlin build 376.46. Does anyone know how to set this up? I know the URL for it is http://192.168.X.X/Advanced_IPv6_Content.asp

Your base router is the DHCP server.

Are you trying to access the Asus via IPv6 or enable the Asus to forward IPv6 traffic?

Regarding forwarding (or "repeating") IPv6, I think the Asus forwards at the MAC layer (OSI layer-2), meaning anything above the MAC layer like IPv4 or IPv6 (OSI layer-3) is forwarded regardless of what layer-3 (or higher) protocol it is, so you do not need to do anything. If you are having problems with IPv6, it is most likely a problem with the client or router, not the repeater.

Edit: Added words for clarity.

I'm trying to use the ASUS as a wireless client bridge. Clients connected to the Netgear R8000 get iPv6 no problem. Clients connected to the ASUS do not get iPv6.

iPv6 Test Results: (when connected to ASUS)

Test with IPv4 DNS record
ok (0.264s) using ipv4
http://ipv4.test-ipv6-ct.comcast.net/ip/?callback=?
Fetches an object that has just an A record in DNS. This is expected to use IPv4. IPv6-only users might still reach this, if their provider has employed a NAT64/DNS64 or proxy solution.
Test with IPv6 DNS record
bad (0.042s)
http://ipv6.test-ipv6-ct.comcast.net/ip/?callback=?
Fetches an object that has just an AAAA record in DNS. This is expected to use IPv6. Users not yet on the IPv6 Internet are likely to see this fail. As long as it fails quickly, it will be OK - for now.
Test with Dual Stack DNS record
ok (0.236s) using ipv4
http://ds.test-ipv6-ct.comcast.net/ip/?callback=?
This is the most important test. This verifies your browser can connect to a site that has both IPv4 and IPv6 records published. IPv4 only hosts should connect fine (using IPv4).
If this test fails or times out, you can expect major problems as publishers start offering their sites on IPv6.

Test for Dual Stack DNS and large packet
ok (0.236s) using ipv4
http://ds.test-ipv6-ct.comcast.net/ip/?callback=?&size=1600&fill=xxx...xxx
Validates that you can connect to a dual-stack server (like the ds test); and that you can send/receive large packets on that connection. If this test times out for any reason, it indicates trouble for World IPv6 Day.
Test IPv4 without DNS
ok (0.209s) using ipv4
http://96.119.0.221/ip/?callback=?
This will try connecting with a literal IPv4 numeric address. This should work for most people, unless they are running IPv6-only. If the first test worked, but this fails, it likely confirms your provider is using NAT64/DNS64; you'll need to only try connecting using hostnames instead of numeric IP addresses.
Test IPv6 without DNS
timeout (15.798s)
http://[2001:558:fc00:100:f816:3eff:fe2b:6488]:80/ip/?callback=?
This will try connecting with a literal IPv6 hexadecimal address. The primary purpose of this test is to separate out your connectivity on IPv6 from your ability to fetch DNS for it. A secondary purpose is to see if you have Teredo enabled; some systems may only use Teredo when an IPv6 address is in the URL.
Test IPv6 large packet
bad (0.051s)
http://mtu1280.test-ipv6-ct.comcast.net/ip/?callback=?&size=1600&fill=xxx...xxx
Validates that IPv6 requests with large packets work. If this test times out, but other IPv6 tests work, it suggests that there may be PMTUD issues; possibly involving IP tunnels. Double check to make sure that ICMPv6 Type 2 ("Packet Too Big") messages are not filtered by your firewall.
Test if your ISP's DNS server uses IPv6
ok (0.358s) using ipv4
http://ds.v6ns.test-ipv6-ct.comcast.net/ip/?callback=?
(This is bonus credit)
This is a test of your ISP's resolver (instead of a test of your host). If this test passes, your DNS server (often run by your ISP) is capable of reaching IPV6-only DNS authoritative servers on the Internet. This is not critical (at this time) for you to reach sites via IPv6.

IPv6 clients that succeed through the Netgear fail through the Asus?

If my posit that the Asus forwards MAC traffic (as a network switch would) is true, you need to look elsewhere for the cause of your problems.

Where would I need to look? Anything wrong with settings? Any bug with the version of the merlin FW build?

Precisely what problems are you experiencing?

Precisely what problems are you experiencing?

Internet works for any device connected to the ASUS, however iPv6 does not - this is the problem. iPv6 works for any device connected to the R8000. Should I upgrade to a newer merlin fw to fix the issue?
