Some additional info: from looking at an ethereal trace, I'm seeing source quenches coming back to the machine VPN'ing in. Interestingly, ethereal also reports an invalid checksum on a bunch of those packets. The strange thing is, this machine has acted as a router/NAT for quite a while and so of all the machines on the network, it's hardware is probably the most stable (easily 150+ day uptimes). Any ideas?

But it doesn't look "crazy" from the netgraph side, just like a lot of packets are being dropped. There must be something specific about your setup that causes this. You're using 4.6.2? Try applying all of the patches in sys/netgraph that are in 4.7-REL that you don't have in 4.6.2... ? -Archie __________________________________________________________________________ Archie Cobbs * Packet Design * http://www.packetdesign.com To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-net" in the body of the message
