ISP Public LAN and WAN with an MX

I have set up a new ISP dedicated line at one of our locations. The ISP has given me static IPs in the form of Public WAN and Public LAN. Can someone assist me with configuring my MX95 to function so that we can use the Public IPs addressed to us but keep the internal NATing that is already set up? I have set up the WAN connection on MX with the listed information and and able able to reach out to the internet; however, I would like to make use of the static IPs provided to us.

WAN Information IPv4
WAN IP Address: 45.88.123.0
IPv4 CR IP Address: 45.88.123.2
IPv4 AR IP Address: 45.88.123.1
IPv4 WAN Subnet Mask: 255.255.255.252
IPv4 Default Gateway: 45.88.123.1

LAN Information IPv4
LAN IP Address: 45.33.105.72
IPv4 Subnet Mask: 255.255.255.248
IPv4 Usable IP: 5

You don't need to do anything additional just configure the WAN, NAT on Meraki is automatic.
