Hi All,

I could use some guidance with troubleshooting a problem I am having currently with OpnSense. Randomly during the day, my entire network seems to freeze up for about 30 seconds to a couple of minutes. I am not sure if its just LAN or WAN but all devices both wired and wireless can't seem to do anything during this, I am leaning toward it being a WAN-related issue as on the odd occasion when the freeze up has been long enough, I am still able to log into the Admin portal on my router. It started about after about 6 months of OpnSense running as my network.

My network looks like the following:

Virgin Media Fibre modem/router (modem only mode) -> OpnSense (Protectli Vault FW4C (Intel J3710) with 2 2.5GB NIC) -> 1GB switch and Ubiquiti Amplify-HD wireless router (Bridge Mode)

I have determined the issue is my OpnSense router as I have removed it from my network and then ran each of the ISP modem and Amplify-HD as the router for a day each and during those two days I did not have any of the freezes. I have also taken the extreme move of completely wiping my router and just having it run as it comes out of the box, just as a DHCP server, no ZenArmour or OpenVPN etc. and I still get the freezing. No matter what configuration I run my network in, as soon as OpnSense is the router, the freezing happens.

My OpnSense is a pretty basic setup, it runs Dnsmasq for DHCP, ZenArmour, and then an OpenVPN connection with some routing rules to push specific network client's traffic over that connection.

I am at a loss at what to look at to try determine what is causing this freezing when OpnSense is the active router on my network, when looking at the logs I am not really sure what I am looking at so probably wouldn't spot the issue if it was staring at me. I do appreciate that this could also be a hardware issue as well.

I could use some guidance on what to look for or potentially even a fix to try as I don't want to get rid of OpnSense as I love the control it gives me, especially along with ZenArmour, about what my kids can access when and filtering out the dodgy stuff as best as possible, but I am getting to the point that the Wife Acceptance Factor is getting very low, so I need to resolve it otherwise I will be gaining an expensive paper weight in the protectli.

Appreciate any help, pointers, etc.
