Hello all,

I initially set up my server back in 2019 ish so my information is horribly out of date. I need to port forward just my https traffic on opnsense as http is not recommended. However my issue is that the way rules were setup 6 years ago is very different from how they are now.

My ask could someone please break it down for me like im 5 how to properly port forward this one port and any other considerations for security when exposing yourself to the internet?

Or just point me towards any documentation that makes it painfully obvious what I need to do?

Could you see the DNS requests coming in in the AdGuard Home logs while the issue was happening?
     I was not looking at the time and I'm hesitant to break it again.
Can you see the requests in AdGuard Home now?
     Yes

At this time should I change System > Settings > General back to something like cloudflare and change Services: ISC DHCPv4: [your interface] > DNS Servers to my OPNSense host? or am I misunderstanding what you are suggesting?

Howdy,

I followed yeraycito's setup guide from September 22 2022 and configured DNS over TLS. It worked perfectly until I suddenly lost internet access. I could still ping 1.1.1.1 from my machine however DNS resolution seemed to be broken.

I reverted the changes and after obtaining a new IP address my internet was working again.

I played around with it and reconfigured everything per yeraycito's guide once again. I then decided to go into:
System > Settings > General
and added my OPNSense box as a DNS server (the thing hosting unbound). The error is now no longer occurring. Is this a step I was supposed to do and was just not provided in yeraycito's guide, or am I now bypassing DNS over TLS (or doing something else equally dumb)?
