Hi.
I have a small NUC-type system running FreeBSD 11.2-RELEASE-p8 serving as the gateway for my home network. It's got an N3160 Celeron CPU (2C/4T), 8GB RAM, and two igb(4) interfaces. igb0 is LAN, igb1 is WAN. pf(4) is configured to NAT my LAN subnets behind a single public IPv4 address. It's also a router for an IPv6 /56 prefix.
Several times each day, the gateway will stop responding on its LAN interface. This can last up to two minutes before it recovers. The system hasn't rebooted and there's nothing in the logs to indicate any problem has occurred.
I am observing this issue from my WiFi connected laptop, but have eliminated the WiFi connection as being a possible cause by pinging both the gateway and another system connected to the same switch as the gateway. Only the gateway pings timeout.
I've tried bumping mbufs up with
I previously ran pfSense 2.4.4 (based on FreeBSD 11.2) on this system without any problems, so this issue is quite frustrating. Can anyone make any suggestions on how to diagnose this further?
Thanks.
