Problem with IPv6

I am trying to get IPv6 working. Comcast said that I was assigned "2603:xxx:yyy:zzz::/56". I have a router/firewall connected directly to Comcast's modem which splits it into 3 VLANs. Everything I read online says that I should use DHCPv6 on my router's WAN interface with a "prefix delegation size" of 56. And to set the "IPv6 Configuration Type" to "tracking". No matter what I do, I do not see any "2603:xxx"yyy:zzz:;/56" anywhere. What I see on the Comcast modem is:

Internet: Active

WAN IP Address (IPv6): [Edited: "Personal Information"]

WAN Default Gateway Address (IPv6): [Edited: "Personal Information"]

Delegated prefix (IPv6): [Edited: "Personal Information"]

WAN Link Local Address (IPv6): [Edited: "Personal Information"]

What am I doing wrong?
