Archer AX20 - IPv6 address not assigned in access point mode
I have a problem in IPv6 address assignment with Archer AX20 in access point mode.
My network configuration is as follows.
==(Optical line) == (Router provided by NTT) ---(LAN)--- AX20 ---(wireless)-- clients.
The router behaves as router for IPv4 and IPv6. And the IPv6 address is determined in SLAAC.
Clients send Router solicit message and the router responds router advertise message.
It works when a client is connected to the router directly, but it won't work for (wireless) clients connected through AX20.
When I reboot my AX20 and clients automatically reconnect, IPv6 addresses are assigned to the clients.
But if I disconnect and reconnect wireless of a client, IPv6 address is no longer assigned.
IP address assignment seems to work in router mode. AX20 has a configuration menu in router mode, and IPv6 is enabled in pass through mode.
But no IPv6 configuration menu is available in access point mode.
This is my guess.
Because RA(Router advertisement) works just after startup, I guess the AX20 intentionally filters out the packets.
I know the router is not fully transparent because "tplinkwifi.net" works even in access point mode. AX20 must sniff packet.
Because ipv6 menu is not available, IPv6 could be configured as "Disabled" internally, but my expectation for access point mode is full transparency like dumb Layer 2 switch.
