IPV6 on pfsense WAN

FOOLiSH86

I have a problem.
my situation is.
ISP Router(ipv4+6)--->PFsense
on the ISP router there is a DMZ with my pfsense, the network works.
on the pfsense wan i have enabled the possibility of dhcpv6 but i don't get an ipv6 on the wan.
If I directly connect a computer on the ISP Lan my laptop for example receives an ipv6. How do I solve this? how do I set my wan on the pfsense?

Is that router using NAT? If not, you won't get an IPv6 prefix. I have my cable modem in bridge mode, which works fine.

yes my proveder is ipv6 in internet and local network.
in fact if i connect directly to my provider's modem i surf and get a public ipv6 and on the LAN
I wanted to understand how to properly set up full ipv6 support on my pfsense

First : a modem is a device that 'supports' only one device connected to its LAN port - this device is then typically a 'outer(firewall) device.
It is possible that you connect a PC, and it then works = obtains a DHCP lease, or uses come kind of PPP(OE) connection.
What is your case ?

Any end device - like a PC, wired, or wireless, or a phone, whatever, asks IPv4 information (IP, network ,gateway, DNS and even NTP and whataver). The DHCPv4 client on the device will do this for you.
There is also a DHCPv6, doing somewhat the same thing (with some nuances here).

Another type of device is a router like pfSense.
It can/will ask a IPv6 for it's own WAN interface.
But will/can also ask for one (or more ?) so called "prefix(s)" so these can be used on the LAN(S) networks of this router.

So : hookup up a PC or hooking up a router : both have different needs.

The "IPv6" question is : can pfSense obtain these prefixs ? If so, you can use them for your LANs on your pfSense.

You might want to mention your ISP, as some might have issues. As for pfSense, you need the modem in bridge mode, as gateway mode won't work for this. Then you need to enable dhcpv6 on the WAN interface. Normally, you use SLAAC on the LAN side. I used unmanaged for RA mode. Try getting started and ask about any issues as you come across them. Also, someone might have already posted configuration for your ISP or similar. Here's the info for mine.
