interface not getting IP despite being configured in /etc/network/interfaces to automatically get one

I'm setting up a router/firewall on an Ubuntu Server box. Since there isn't any documentation (that I could find) to do this with netplan, disabled it and installed ifupdown since there are plenty of tutorials for it.
While my LAN adapter is correctly assigning IP addresses to connected devices, the WAN adapter doesn't even show up in /run/network/ifstate. I have to manually add it and then run ifup enp2s0 with enp2s0 being the interface name.
This is my /etc/network/interfaces file:
# /etc/network/interfaces -- configuration file for ifup(8), ifdown(8)
# Generated by debian-installer.
# The loopback interface
auto lo
iface lo inet loopback
# WAN interface
auto enp2s0
iface enp2s0 inet dhcp
# # LAN interface
auto enp1s0
iface enp1s0 inet static
address 192.168.0.1
network 192.168.0.0
netmask 255.255.255.0
broadcast 192.168.0.255
Shouldn't the line auto enp2s0 ensure that it should be configured every time networking starts?
