click on the ... at the end and hit yes for delete

The only action behind ... is 'Reset certificate'. There is no such an item like "Delete".
Resetting does not remove it.

I would like to delete my obsolete certs from ACME, but I was unable to find a way to do so:


How can I do that?

I am sorry but just after posting the above question I enabled the following option:
Do not use the local DNS service as a nameserver for this system
and since then I was immediately able to ping the internal hosts from my OPNsense firewall!

Hopefully I did not break something else with it ;)

In my home network I have an internal DNS server hosted by Synology DSM. The latter is serving my internal DNS hosts names and is forwarding DNS queries for external hosts to Google DNS service. Simple and straightforward setup.

My DNS server IP was added to the System > Settings > General, DNS servers field in OPNsense, as well as the DHCP configuration for the LAN interface.

Everything is working great for all my devices, i.e. both internal and external host names are being resolved correctly. If the internal network names have their external equivalents (for example my www.wojtaszek.it) the name is being resolved to local IP (192.168...)

For some reason though the OPNsense server itself can't resolve my internal host names i.e. when pinging www.wojtaszek.it I am getting the public IP address (91.90.179.152), not the private one (192.168.... etc).

It worked fine for me before and at some point stopped. What do I do wrong? How can I troubleshoot that?

Update: I found the fix. I had to go in my Unbound DNS settings and add an ACL to allow the Wireguard network to access DNS.  Now, I can point the client to my OPNsense system for DNS and it works. 

I have the same issue but I do not use Unbound DNS but instead I employed AdGuard to lookup for internal hosts by their dns names. I was unable to find anything like DNS in AdGuard so I am not sure how to let the WireGuard clients access the names. Any clue how to achieve that?

Do you have the QEMU Guest Agent installed? It's available as a plugin. That should enable Proxmox to communicate with the guest, iirc it will also help display correct memory usage stats.

Not really. I installed the agent on other Linux VMs but have not tried with OPNsense yet.

Frankly, this is my first two weeks of my OPNsense journey, same for Proxmox, so I am still on the learning curve ;)

The command confirmed what I see from the GUI.

Thanks buddy, that was helpful.

I recently expanded memory for my OPNsense virtual machine hosted on Proxmox, from 2GB to 8GB. Here is what I can see in the system info:



Just about 6% of memory utilized.

And here is what Proxmox shows for the same virtual machine



Over 7GB of memory is being used!

Which one is telling me truth? Funny this is that before expanding memory the system showed less than half memory used in Proxmox for that VM.

I created my own block list txt file and I put it on my web server hosted on my internal network (behind the NAT, but facing the internet). Then I created an alias entry in OPNsense where I entered the url to the txt file:



After saving it does not load any entries as you can see on the screenshot below:



even though there are several hundreds on the list:



The log shows that it was caused by a name resolve error:



When I ssh to opnsense and try to ping the host name it is indeed unable to resolve the name. It resolve it to the public IP not the internal private IP:



So my question is now: how to make OPNsense to resolve the name of the host to private IP/internal email address?
I tried to add it to the /etc/hosts name on OPNsense. It helps in terms of pinging the host from SSH, but the IP list is still not loaded in the alias entry...
I also tried to play with NAT reflection settings but honestly I do not feel comfortable with it yet...

Any idea how to fix that?
