My network looks like this:
(Cable Modem/Router) <-> (PfSense Router) <-> (Internal Hosts)
The IP (changed for security) of my cable modem is:
IPv6 Address 2001:1:a481:300:6eb0:ceff:fe8d:f25b/64
IPv6 Prefix 2001:1:a481:300::/56
What should I set as the LAN and WAN IPs of my PfSense Router?
Also in the DHCP6 server, I'm asked to complete:
DHCP6 Range
DHCP6 Delegated Prefix Range and Subnet
What should my router (pfSense) IP be in the DHCP6 settings for the clients?
In general I'm confused how to subnet this properly. This is for a very simple home network, but I'd like to learn how this stuff works. Any help would be greatly appreciated!

if you have 56 prefix it would be nicer to include zeroes
completed prefix looks like this:
now we can see the prefix
In IPv6 the smallest subnet size (prefix) is 64; so you have 8 more bits to create subnets (2 zeros after 3)
if you want only one simple subnet for your homenetwork, the easiest way is to choose some address from your subnet - prefix, for example:
this will be your home subnet now you have to choose the addresses for wan/lan for ex.:
DHCPv6 personally I don't prefer this. IPv6 have included autoconfiguration using NeighborDiscovery protocol. But If you want It the prefix would be
and DHCPv6 range for example
and at last:
You also have to ensure that correct routes are on your devices and the traffic will be routed
