I have a 3 site site-to-site OpenVPN, all sites running a virtualized copy of pfsense. The main site is hitting it's CPU limit on a single core, was looking to just give it another vCPU, wanted to confirm this is fine or not.
Main site runs version 2.2.1 (i386)
It is. No problem.
Is OpenVPN still single-threaded? Why not use regular IPSec for site-to-site connections?
