IPv6 works on pfsense but not on LAN side
-
I spoke too fast.Although ipv6 works correctly for 2-3 days, then suddenly it stops.Even if I reboot the device it dozen't work.The only way it can work again is by modifying the value "ipv6 prefix id" on lan to something else for example 6,8,f etc. Any ideas why this could happen?

I have the same issue, same hardware and version, different ISP (Hughesnet Gen4). I have native IPv6, I get a /64 on the WAN side, I can't get the right allocation on the LAN side because they hand out a /61 and that isn't a choice in the pull down menu, but if I pick /62 it all seems to look right. none of my hosts on the LAN side (pretty much all apple devices at the moment) get an address.
radvd is running in services, but because I have track interface for LAN, not a static, I can't set anything for the RA, and I don't know what the defaults are.
I see the RAs in tcpdump from fe80::1:1, which is the LAN interface address, and they have a /63 prefix in 2001: that matches the LAN address on the pfsense box, but the host never gets an autoconfig address. I use autoconfig on the same laptop at work every day, and it's fine there.
I'm new to pfsense, and I've only done IPv6 routing on enterprise-level gear, not home network stuff, but it's the only public address I can get out of Hughesnet, so any ideas are greatly appreciated.
