Using ipv6 passthrough on the second router, and making multiple LANs sharing the same /64 does work. See details in this thread: https://www.snbforums.com/threads/ipv6-on-gnp-using-passthrough.94787/

My issue went away after I swapped the router, so it is indeed a hardware problem. I encountered other issues as discussed in this thread, so I had to RMA the router. My WAN issue went away since I have the replacement router. DHCP now is stable on the 2.5GB connection between xfinity modem and...

I read somewhere that passthrough mode will only allow ping6, not anything else. Not sure if that is true, can you try some ipv6 traffic from your main network to GNP network other than just ping6? eg: ssh to a ipv6 host in GNP network? I guess if you don't need any advanced firewall between...

If I understand it correctly, sharing the same /64 across vlans will flatten the internal ipv6 network, and beat the purpose of separating vlans from ipv6 perspective.

openwrt folks also does the similar workaround https://forum.openwrt.org/t/configure-dhcpv6c-on-wan-for-multiple-pd-requests-for-at-t-fiber/99371/39 Since Asus also uses odhcp6c to request prefix delegation, maybe we can do the same, and then use those different requested /64 for different...

ATT does provide 8 /64 IPv6 prefixes. It is just you have to request them individually. Here are some discussions how pfsense did it

I thought about this, and here is an idea that may work but I don't have the spare equipment to test it before changing the live network. It would great if someone who have a test lab and spare asus pro routers to test the idea. On Asus side: 1. Configure Asus to use 1G WAN and leave the 2.5G...

Yeah, I searched earlier and found [one] but no answer. Most posts are for multiple vlans on LAN side only, not across WAN and LAN.

Here is the setup: - 2.5G managed switch in Room 1. The switch has WAN as vlan tag 100 and LAN as vlan tag 200. - Asus RT-AX86U PRO is in room 2. There is only one ethernet cable running between the two rooms. The plan is to make this ethernet connection as "trunked" with both vlan 100 and 200...

I did more searching in this forum and found this old post which indicates using IPv6 passthrough mode on router 2 will work. I assume in this setup, the LAN 2 will use the same /64 from LAN 1 subnet.

Since I don’t have static IPv6, does that mean each time router 1 is rebooted, it will get a different PD? So we have to manually update router 2 for LAN 2 to use the new prefix .

On my RT-AX86U Pro, "ethtool eth5" gives I am puzzled by the line "Advertised auto-negotiation: No". Does that mean the 2.5G on RT-AX86U doesn't support auto-negotiation? If I check a LAN port, eg: "ethtool eth2", I get: Now you can see "Advertised auto-negotiation: Yes". Does this mean...

More update: On the bad router, "ubinfo /dev/ubi0 -a" command gives: So total bad block is about 253 / (1763+253) = 12.55% I sent it for RMA and just got it back today, now "ubinfo /dev/ubi0 -a" command gives: so now there is 0 bad blocks and I can upgrade to RT-AX86U_PRO_3006_102.4_0...

Will it work if I configure the second router using IPv6 Passthrough, instead of Native? Will that make LAN2 clients get IPs from LAN1?

Does Asus/Merlin support passing ipv6 prefix to downstream router? Current setup: ISP -> Asus/Merlin router 1 -> LAN1 Router 1 is configured Native IPv6 with PD. Prefix size 64 and it is used on LAN 1 with Stateless. Everything works. The plan is to add a downstream router: ISP -> Asus/Merlin...
