VPN Setup in "out of path" deployment style
I plan to setup PFSENSE as a VPN Server in a "out of path" style.
My existing infra already has PFSENSE as firewall, but dont plan to include the VPN function into this main firewall.
Plan to deploy another PFSENSE as a dedicated VPN server to cater for a group in my company.
Any suggestions? How many network interfaces needed for this deployment?
