Hello,

we want to setup Simple SDN zones with IPv6 but can't find any documentation about how to configure SLAAC or DHCPv6 for a Simple SDN zone in the WebUI.

Goal:
Netcup-VPS with two public static IPv4 addresses and two public static IPv6/64 prefixes -> Headscale VPN -> Proxmox VE node -> SDN zone.

One public static IPv4 address and one public static IPv6/64 prefix are used for the VPS itself and the other public static IPv4 address/IPv6/64 prefix shall be routed into a Proxmox VE SDN zone called "dmz". The Headscale coordinator and a Tailscale node are running on the VPS and another Tailscale node is running on the Proxmox VE host.
One public static IPv4 address and one public static IPv6/64 prefix are routed to the tailscale0 network device on the Proxmox host.

Dnsmasq supports DHCPv6/SLAAC/Router-Advertisement but how does it have to be configured for Simple SDN zones in the Proxmox WebUI?

Thanx for any Hint :)

Similar issue here. I have a /40 prefix but I'm unable to set up dnsmasq to assign DHCPv6 or SLAAC.
Using the similar config as IPv4, I got:
Code:
prefix length must be at least 64 at line 3 of /etc/dnsmasq.d/simple/10-simple1.conf
and for dnsmasq config:
Code:
dhcp-range=set:simple-2602:F9B1:1::-48,2602:F9B1:1::,static,48,infinite

In my case, I prefer to use SLAAC. So I manually set dnsmasq config to:
Code:
dhcp-range=set:simple-2602:F9B1:1::-48,2602:F9B1:1::,ra-only,48h
I can get an IPv6 address in VM, but the traffic doesn't go through.
