HP t620 Plus pfSense Firewall / Router Turnkey ready to use in your network!
The t620 Plus is fitted with a more powerful
AMD Quad-Core GX-420CA 64-bit SOC (2.0 GHz, 2 MB L2 Cache) with AMD Radeon HD 8400E (600MHz GPU) Graphics and is quite a capable device to run pfSense.
A Dual Intel Network Card is installed, the native (Realtek) Ethernet port can be used for a DMZ.You don't need multiple LAN ports on the router, you plug the LAN port into a switch for multiple connections.
Memory upgraded to 8Gb85 watt Power Supply included.The included stand can be mounted for either Horizontal or vertical orientation.
To setup, connect the LAN port to your computer, use your browser to go to 192.168.20.90 to get the dashboard where you can set the features to your liking. Usually you will want to change the LAN address to something like 192.168.1.1 or whatever your current router is set to. Remove your current router and plug your WAN into this pfSense firewall / router.
There are many sources of information about setting up your pfSense router on the internet - Google "pfsense" for info.
I cannot provide further assistance, sorry.
