Building a lab, interfaces file issue, networking service won't restart because of ifup

Hello (beginner to linux networking), I'm trying to build a lab in VirtualBox with a Debian GLPI server for school, the VM has 2 network interfaces : a NAT one in dhcp (eth0) and the other one (intern) is in static for local network (eth1). Dumb question but what is the difference between enp0s and eth ? I tried this config : auto eth0 iface eth0 inet dhcp allow-hotplug eth0 auto eth1 iface eth1 inet static allow-hotplug eth1 address 172.16.2.56 netmask 255.255.255.192 network 172.16.2.0 gateway 172.16.2.62 broadcast 172.16.2.63 I lost internet when making changes to the eth1 card which is unfortunate cause i need it to build GLPI, i tried different confs but cannot make the networking service restart, ifup is breaking on the address line : misplaced option. Basically i want my NAT to come back and stay up so i can have internet on my VM + having eth1 for local purpose and hosting the GLPI ITSM service. I don't know if i made it clear, if asked i will give you details, thanks for your help in advance.
