What problem are you trying to resolve.
No gateway? Without one my router cant do much with the address and prefix.....

As I mentioned before, your gateway should be fe80::201:5cff:feb1:da45. You shouldn't have to do anything for that to work. Take a look at the source address for the 2nd and 4th packets and you will see that. I just checked mine and it's the same as it was in a packet I captured over 2 years ago. Unlike IPv4, there's no explicit gateway. It's whatever the source address is.
I can only think you changed something that's causing this. Try connecting a computer directly to your modem and see if it works on IPv6. That should help determine where the problem is.
You might also try a new config from scratch, to see if you have something mis-configured. You can save the existing config when you do that.
BTW, where did you try to set a gateway address? I don't recall that setting anywhere for IPv6.

The only thing i did is enable the option to not wait for RA, otherwise it wont even assign the address to the interface. Spoofed the mac of the router and plugged in one of my laptops:
Same thing, gets address without gateway and no network.

You mean that Use non-local gateway? You should have no reason to be doing that.
If you put your modem into gateway mode, does it work properly, in that computers connected to it get IPv6 addresses? I had a problem with my ISP a few years ago and found even gateway mode didn't work at my next door neighbour. ISPs will generally expect you to try with gateway mode.

Nope, all is left default in the "WAN_DHCP6" gateway. I created a 2nd one with the fexx:: address as i wrote earlier, it seems to work for now.

What i have is a plain old cable modem without modes, its an arris cm3200.

If the gateway you use is that fe80::201:5cff:feb1:da45 I mentioned, then I have no idea what the issue is. But if it's working by using that, then I guess leave it the way it is.
BTW, no need to hide link local addresses. Outside of the local LAN or connection, they are irrelevant.

then I have no idea what the issue is
The fact that i have to go around hunting for it and setup a gateway manually? Its just beyond my why cant they just enable RA and call it a day.....

I just ran Packet Capture on my WAN port for a few hours. I saw no RAs. Other other hand, I was seeing RAs every few minutes on the LAN side. I don't think RAs are normally provided on a cable modem connection, as the necessary info is contained within the DHCPv6-PD packets. However, you might ask your ISP why a computer also doesn't work. It doesn't require any configuration.
When I had a problem with my ISP a few years ago, I arranged for a senior tech to come out with his own modem, to see if it would work. It failed, as I expected. He then went to the office and connected his modem to 4 different CMTS. It failed only with the one I was connected to.

Well if this was normal behavior pfsense wouldnt have issues setting the wan connection up. But it does so i can only assume its out-of-spec..... And as i wrote before the ISP basically brushing me off.
And just as an extra bit last night i had internet outage, the fe80:: gateway i set manually isnt working anymore. Also still no gw address from the ISP.

You said an ordinary computer doesn't work. Try complaining about and see what they say. I know it can sometimes be difficult to get through support.
