[robinjoo1]

@RMerlin Are you planning to fix what ever Asus broke with IPV6 in there latest 3.0.0.6 firmware for the AX86U Pro ?

is ipv6 broken with asus firmwares ?

is ipv6 broken with asus firmwares ?

It is with the new 3.0.0.6.102.34312 the latest for the AX68U Pro.

Doubt it....why would say that? Maybe start with your ISP provider.

so not with other models , my isp has a global ipv6 issue logged in a ticket sinds month 7 of 2023 unable to give me updates as to why it sometimes stops working so i am trying to pinpoint where the root of the issue/cause is

BS it's already been confirmed. Native IPv6 is broke in the latest Asus build for the AX86U Pro. Period. Nothing to do with ISP. Read the thread about the latest build before posting nonsence.

Can't speak for other models as far as i know its only the AX86U Pro.

@Analog-1 wonder how many are using that firmware without mentioning IPv6 problems. I see nothing in the changelog that should affect IPv6, and only 2 people having problems.
I'm not saying there isn't a problem, just that there's not many cases.

Not sure. But i have tested this along with a friend and it just does not work. He uses Spectrum i am using Comcast. All other firmwares from Asus and Merlin IPv6 native works 100% no issues. Load this new firmware along with factory reset and native IPv6 no longer functions for both of us. As stated in the other thread others are also having the issue.

- Corrected a display issue in the OpenVPN server that prevented IPv6 settings from showing correctly.

Maybe this somehow changed something i am no expert on firmware. Asus also does not include many changes in there changelog only what they want to post. So who knows.

 

[Analog-1]

Ok just for more confirmation. Just reflashed Merlin 388.7 then flashed Asus 388.24199. NO factory reset all settings left alone and instantly IPv6 was restored and working perfectly.

I haven't been able to enable IPv6 for a year or so now. When I do, my download speed drops by 1/2 immediately. This is over multiple Rmerlin firmware versions and, I think, on two routers (my current, as well as an AX-86U I used to own).

I don't know why this is, and in any case I don't need IPv6. But, it's just weird. It didn't do that a couple of years ago. Below are screen captures from tonight. The IPv6 speeds v. IPv6 when disabled are apparent.

I can't speak for all models but when I enabled IPV6 on the GT-AX11000 Pro model...I never seen issues (latest asuswrt-merlin) . You seem a little agitated for no reason lol.

You also mentioned both the AX68U and the AX86U...so which is it?

 

[Kingp1n]

It is with the new 3.0.0.6.102.34312 the latest for the AX68U Pro.

So is it AX68U or AX86U?

 

[Kingp1n]

@RMerlin Are you planning to fix what ever Asus broke with IPV6 in there latest 3.0.0.6 firmware for the AX86U Pro ?

Just use latest AX86U or AX68U asuswrt-merlin firmware. You'll stop stressing alot with your router!

 

[RMerlin]

Moved off-topic talks about Asus' firmware to its own thread, and removed unecessary rude posts. Folks, please behave.

There's a problem with the firewall rules, there are no rule to allow traffic going from LAN to WAN, so all IPv6 outbound traffic is getting dropped:

Release - ASUS RT-AX86U Pro Firmware version 3.0.0.6_102_34312 - 2024/05/09

Upgraded my network to ASUSWRT 5.0 and 2.5Mbps backhaul... not using IPv6. Traded in a burned out RT-AC86U to Best Buy for 15% off a new RT-AX86U Pro (2023 Vietnam) on sale for $209... and then I asked the BB sales rep if I could keep the three antennas and they let me... very much a 'best...

[robinjoo1]

Not sure if I'm having the exact same issue, but I am having the same symptoms. Working ipv6 local pings with public ipv6 address, but no outbound traffic to internet sites through ipv6 is available.

OK, best to start by telling us what router and firmware you are using.

GT AX-11000 Pro with merlin 3004.388.7.

IPv6 leases for clients show up on hurricane electric and I can can ping / login via lan IPv6 addresses. All outgoing / outgoing IPv6 connections fail. Currently on zentro which claims IPv6 support and has IPv4 with CGNAT. It uses a fiber backbone and then distributes via cable in this apartment building.
