Negative, we won't be spending that on that, there are a number of far higher priority issues that need ipv6 support.
And nat isn't one, NPt essential failover functionality, so that was added. The input validation is broken though.
Yes. the length must be the same for the WAN and LAN, but you can do smaller lengths, but the smallest is the common denominator.

hi bkraptor,
i'll have a look this week if time permits. I might be able to do random prefixes with the cisco 1811 I have here.
I'm still quite amazed that ISPs think that handing out random addresses and even more so, random IPv6 prefixes is a good idea. It wrecks so much havoc because the LAn addressing changes as well.
Would you mind contacting your ISP if they are considering handing out "static" IPv6 addresses? I know they want to keep their (old) business model they applied to IPv4 addresses going, but the impact in IPv6 is far worse then in IPv4 where just the router changes addresses.

Your gateway can be a link local address. There is no harm in specifiying the gateway as a link local or global address since it is the same host.
It makes perfect sense for gateways since these are normally always directly connected.

Note: Some ISPs will allocate you a /48 and assign the 1st 0000 subnet to the directly connected interface. They will likely also have a static route that points the /48 to the ::2 address. This is what your downstream router needs to be addressed as.
You configure the 1st /64 you got allocated on the WAN. You configure the <prefix>:0::/2 on the WAN, /64 or /126 does not specifically matter. You configure a network out of <prefix> other then 0 on the LAN, for example give the LAN address <prefix>:1::1/64 Go to the DHCPv6 server page, select assisted, enable DHCPv6 server too.
All clients should now pick this up on the LAN in about 10 seconds.
If you have more interfaces you can configure other <prefix>:n::/64 networks locally. 2-ffff. If you have a internal router, create a static route for <prefix>:nn00::/56 to this router so you repeat the steps above.
Note 2: this has nothing to do with pfSense perse, this is basic subnetting 101. Let the NAT go folks. It isn't there.
