This was on a box that had a regular set of OPEN rules. i.e. 00100 allow ip from any to any via lo0 00200 deny ip from any to 127.0.0.0/8 65000 allow ip from any to any 65535 deny ip from any to any Also, in terms of queue drops, the fastforwarding did make a small difference, but I still am seeing a series of drops somewhere between 5 and 10min. If you think it would be useful to track down to see if it is exactly some interval, I can do so. ---Mike To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-net" in the body of the message
