General Discussion / Re: WAN went down. Reboot fixed it.
« on: June 22, 2024, 09:05:37 am »
Hi,
I just wanted to share my fix on strange problem on one of my customer networks.
Their internet access stopped once or twice per week (maybe 50 client pcs) but I always could connect to terminal via VPN and reboot firewall.
WAN interface was Intel NIC, LAN Realtek NIC.
Only change I did, replaced Realtek with Intel NIC and problem is no more.
Maybe using Realtek driver plugin would have helped also but I try to avoid "modifying" Opnsense as much I can.
I have a feeling that this problem manifests itself only when traffic is high. I have similar setup with much smaller network and this has happened only once in 12 months.
BR, Markku
