Pure IPv6 on SBG3500

MilDro

Hello Zyxel,
we have SBG3500. Our ISP give us ONLY IPv6 2a00:xxxx:xxx:xxx::/64 subnet and his gateway 2a00:xxxx:xxxx:xxxx::1/64 at Eth-WAN port. without IPv4 connectivity.

We liked to have static or DHCPv6 IPv6 address from this subnet at LAN client and SBG work as Firewall only.
We tryed change mode SBG3500 to router, create new WAN IPv6, but nothing work.
Can you explain or provide basic guide, what's mode for WAN and LAN is required to set to work at SBG?
Thank you

@MilDro,
For the setting of IPv6, you need to get the IPv6 WanIP, IPv6 Wan Gateway IP, and IPv6 Lan prefix from ISP. Please check the below steps as your reference.
On Ethernet wan page, select "IPv6 only", and fill wan IP and gateway IP.
On lan page, fill Lan prefix  on Lan IPv6 Address Setup, and enter DNS server on IPv6 DNS Values.

Thank you, i try.
P.S.
If ISP don't give me special etc. ::10/60 WAN IP and /64 LAN prefix, but only /64 and his GW ::1/64, it's not possible routing/firewalled this to LAN client? Than, my only option is bridge this network?

Hi @MilDro,
If you only get :/64 prefix from ISP. it cannot subnetting a v6 range for Lan side host routing.
I would suggest bridge the Wan-Lan interface(V6 interface)
