@benoitm974 

 

Could you please clarify whether this refers to the LAN IPv6 address of the router or the IPv6 address of the client device connected to the BE800?

 

Also, who is your Internet provider, and what type of IPv6 connection do they offer?

I'm using "custom" mode in IPTV with VLAN tagging 100 prio 0 for Internet all port allocated to Internet.

In IPV6 i'm using DHCPv6 with prefix delegation enabled, my provider allocates a prefix; which is recognized by the BE800.

The routeur then assign a LAN ipv6 based on mac address in this prefix received via DHCP

 

This LAN ipv6 can be ping from WAN/Internet (no toher access, just ICMP)
