A few comments i like to add from my experience:
- If you use DTTS on pfsense, don’t use the enablers on the dashboard, as they will lock up the pfsense, rather use the rules in the firewall.
- Disable IPv6 or IPv4 prior to enabling DTTS, as DTTS doesn’t support Dual Stack. (this can cause disruptions with the internet, if both are enabled with DTTS)
