Unable to connect to LAN interface after some time.
I've got PfSense 2.3.4 running on a Proxmox VM and are running into an issue. WAN interface is connected to my network and the LAN interface is on a closed internal Proxmox network.
After about 1-5 hours I'm unable to ping the PfSense VM on the LAN interface and I have to reboot the PfSense VM. Other VM's on the same "internal" switch can still ping each other so the problems seems not to be Proxmox networking.
When I open the console for PfSense on Proxmox, I can't ping anything on the internal network. Logs show no errors that I can see.
I know there was a strange bug earlier related to this, but it should have been fixed some time ago (the thread has even been locked).
I've tried to reinstall and reconfigure but same thing seems to happen every time. It's got 1Gb ram and 16Gb Hdd, so resources should not be a problem.
Anyone know what the problem could be?
