Opnsense needs a weekly reboot

[crazywolf13]

Hi

It's very difficult to explain, but around weekly, to half weekly I have to reboot my opnsense, because some of my LXC's in my proxmox cluster loose internet connectivity-> nslookup works, outside ping not. I've found this very difficult to track down, finally I ended up at opnsense/my isp router, mostly a reboot of opnsense solves this.

My home network is structured the following: isp-router with home lan->opnsense it's own subnet->clients as peoxmox.


I'm not really sure how to debug this and hope for some guidance on how to advance to this, thanks!

Let me know if any more details are needed.
Thanks a lot!
