Best way to renew certs with exchange and pfsense
Whats the best way to renew SSL Certs and keep them updated in exchange also? Currently using Let's Encrypt which Expires Every 90 Days. I know ACME can keep pfsense up to date just wondering how to deploy that updated cert to Exchange unless I do it manually. I have multiple SSL sites running right now and I change stuff frequently so I was trying to stick with a free cert since Squid can only use 1 cert on the reverse proxy.
