I had to go in and add a second network adapter.

When I tried to ping there was no outgoing traffic.
I tried setting the interface for WAN again and did the upstream gateway correctly and the ping worked.
3 tech terms
Firewall: A device on the network that monitors incoming and outgoing network traffic. It uses a set of defined rules to decide what is allowed through and what is blocked. Provides a barrier between an internal network and the outside. Can be a physical device or SaaS.
Dynamic Host Configuration Protocol (DHCP): is a network protocol that is used to configure network devices to communicate on an IP network. A DHCP client uses the DHCP protocol to acquire configuration information, such as an IP address, a default route, and one or more DNS server addresses from a DHCP server. The DHCP client then uses this information to configure its host. Once the configuration process is complete, the host is able to communicate on the Internet.
Default Gateway: Device/ router that connects a local network to the internet (every device that wants to connect to the internet needs to know it). I am slightly confused about the difference between the default gateway and the Upstream Gateway It allows user to access servers and devices outside of their network — all the traffic they send and receive goes through it. Without a default gateway, browsing the internet would be a much more laborious effort.
