Configure Palo Alto PA-220 to work with Leased Line (MIA)

We have a Palo Alto PA-220 that needs to be configured to utilise our new leased line.

The device is currently online and has been configured up until the point the interfaces need configuring.

We have been given the following from Virgin Business as their kit has been installed in the rack with a single Ethernet hand off for the Palo Alto appliance.

The details we have are:

LAN Network
Gateway IP Address
Subnet Mask
Network Range
Primary DNS
Secondary DNS

(Exact IP information to be provided upon start).

Our Setup would be:

Virgin Business Cisco Gateway --> PA-220 Ethernet Port 1 (Configured with above details) --> PA-220 Ethernet Port 2 LAN

We have the the Threat Protection license and would like the PA-220 to act as our Security Appliance for our LAN.

Thanks!
