Multi LAN+Milti IPv6+Multi WAN

[yon]

Now I have setup 2 LAN 192.168.101.1/24 and 10.10.10.1/19, 2 IPv6 he.net tunnel for 2 LAN.

and creat ipv6 Gateway Groups for loadbalance.

but only main LAN's ipv6 address can visit from External internet network. Second LAN ipv6 address can't open from External internet network.

How I do Second LAN ipv6 address can  open from External internet network ?
