Requesting verification of ZBFW config on C1111-4P

[train00wreck]

Hello, I recently acquired a C1111-4P device that will be replacing an EOL Ubiquiti router. I am wanting 2 inside VLANs, IPv4 DHCP client on the WAN interface g0/0/0, IPv6 prefix delegation from the WAN with /64s on the VLANs, and eventually site-to-site IPSec to another site. I'd like to see if this config looks alright and for any improvements anyone might be able to provide. Internal testing seems to be secure enough, an NMAP port scan on the WAN interface shows no open ports aside from a "closed" response on UDP port 500. Thanks in advance.
