I do not have NUT installed. I found these entries in the backend log, but they aren't too helpful as there is no clue to why apcaccess returns exit status 1:

I performed a series of updates after returning from holidays. I updated 26.1.8_5 --> 26.1.11_10 --> 26.7.1_1 --> 26.7.2_2. The apcupsd plugin no longer starts and on the dashboard it states "Error: empty output from apcaccess". I think it broke already with the update to 26.1.11_10, but I am not sure.

Is this a known issue? There is no error in the log, just a notice that apcupsd is starting.

In the client peer definition, it's 0.0.0.0/0. On the OPNSense side, it's 192.168.5.2/32.

I must admit that no matter how much I read about firewall rules, it never becomes intuitive or clear to me...so please, if anyone can help me here.

I have a working Wireguard set-up so that I can access my OPNSense router at home from any external location. When I connect, I get access to the LAN, I can manage my router and I can access my NAS via the LAN. However, I cannot access the WAN. I assume I need to add some rule to the firewall, but I really can't figure out how this rule should be defined.

I have attached screenshots of the existing rules for Wireguard and Wireguard (group).

OK, what I am missing is the part of how to set up the VLAN so that all traffic from it routes via the VPN.

All necessary steps are explained above.

If you have trouble anyway, show all details of your settings, please.

OK, here goes. It's the first time I respond to that type of request so if there is a different way I should share the settings, please let me know.

Gateways:



The two relevant VPN interfaces:


Details:



Assignments:


Devices:


Aliases:


Firewall:





DHCP:

But do you have a managed switch to tag the traffic of this VLAN, and have setup your interface in OPN to act as the trunk from it?
If not, you don't have a VLAN but perhaps a separate network on a separate interface in OPN? I'm a bit unclear.

Yes, I have a managed switch for the Ethernet connection, but I also have my Unifi AP that will broadcast a separate SSID for the VLAN (I am doing this already for another VLAN). The WiFi connection will be the main way this VPN VLAN will be used, the Ethernet is just a back-up.

OK, what I am missing is the part of how to set up the VLAN so that all traffic from it routes via the VPN. What I have tried is:

1. Create a VLAN
2. Create an interface that is assigned the VLAN device, a static IP of 192.168.6.1 and a configuration of 192.168.6.1/24
3. Set DHCP to hand out 192.168.6.20-200 to clients on the VLAN interface

Now I am not clear on whether I should
a. Create an outbound NAT rule that directs all traffic from the VLAN net to the VPN interface,
b. Create a normal rule that passes all traffic coming in on the VLAN interface to the VPN interface,
c. Create a bridge between the VLAN and VPN interfaces, or a mix of all three.

I see in the interfaces overview that the new interface has IPv4 and routes set to 10.100.0.2/16. Is this the range of addresses that will be handed out to clients connecting to the VLAN?

This is your VPN client IP.
It's not range, but just a single IP and you cannot hand it out to any other device.

If you route traffic to the VPN server, the suggested outbound NAT rule translates the source address into this one, so that responses are coming back to you.

There is nothing to configure in the VPN interface settings. Just enable it.
IP address assignment is done by the VPN server.

Right, but what local IP address does a client connecting to the VLAN get? In order for the NAT rule to translate source addresses, there need to be source addresses to translate...I must be missing something?

Many thanks!

I see in the interfaces overview that the new interface has IPv4 and routes set to 10.100.0.2/16. Is this the range of addresses that will be handed out to clients connecting to the VLAN? If I would like it to be something else (I was planning similar to my LAN but with the same octet as the VLAN number), how do I set this? Do I specify "DHCP" in "IPv4 configuration type" under the interface settings, and/or set up a range under Services > ISC DHCPv4?

I am trying to set up so that all traffic on a VLAN gets routed out via a VPN client. I have read lots of tutorials and many posts, tried many different settings but with the instructions all being of different age they are intended for different versions of OPNSense and I am never sure which steps have changed or become redundant.

I have a OpenVPN client instance that is showing as connected, and I would like to link this to a VLAN I have already created. I get a bit lost in which steps are required manually and which are done by OPNSense automatically when it comes to

-interfaces
-devices
-gateways
-firewall aliases
-firewall NAT
-firewall rules
-DHCP

Is there a howto/tutorial based on the latest OPNSence describing how to do this? I run 25.7.2.

For ISP reasons, I am forced to connect my OPNSense router behind my ISP's fibre router, set to DMZ. When I compare the bandwidth I get directly from the fibre router to what I get through OPNSense, there is a significant reduction (although an improvement in bufferbloat). What could be the different contributing factors to this? In terms of hardware, the OPNSense router has:
CPU: AMD Embedded G series GX-412TC, 1 GHz quad Jaguar core with 64 bit and AES-NI support, 32K data + 32K instruction cache per core, shared 2MB L2 cache, 4GB DRAM
NICs: i210AT 1Gb/s

Are there specific OPNSense configuration tweaks I should try to reduce the bandwidth reduction?

OK, so that is what I don't have - the graph time is UTC while the system time is CEST:

Does your System Information gadget show the same time as the latest time in the graph?

I have been annoyed for some time that the graphs in the Reporting module use UTC time rather than the system time that is shown elsewhere, e.g. in the System Information gadget on the dashboard. Is there no way to get the Reporting module to respect the system time zone?

I searched for previous posts about this but only found this old thread from 2020.

If this needs to be an enhancement request, where do I post it?

[Kudos and thanks]

Successfully upgraded from 25.1.11 to 25.7.1_1 without a hitch on my APU2E4 with i210AT LAN, AMD GX-412TC CPU and 4 GB DRAM. Unifi, Adguard, os-acme and a few other plugins all work as before the upgrade.
Kudos and thanks to all that help improve this system for all of us!
