Thanks for the reply. The ICMP was more experiment than anything, I've
sinced removed it. Here are the results of the show commands:
cramster# ipfw show
00050 14819576 8458459132 divert 8668 ip from any to any via dc0
00100 250 32470 allow ip from any to any via lo0
00200 0 0 deny ip from any to 127.0.0.0/8
00300 0 0 deny ip from 127.0.0.0/8 to any
65000 44478701 31835950367 allow ip from any to any
65100 0 0 pipe 1 ip from 10.0.0.8 to any
65200 0 0 pipe 2 ip from any to 10.0.0.8
65535 0 0 deny ip from any to any
cramster# ipfw pipe show 1
00001: 50.000 Kbit/s 2000 ms 10 sl. 0 queues (1 buckets) droptail
mask: 0x00 0x00000000/0x0000 -> 0x00000000/0x0000
cramster# ipfw pipe show 2
00002: 150.000 Kbit/s 2000 ms 10 sl. 0 queues (1 buckets) droptail
mask: 0x00 0x00000000/0x0000 -> 0x00000000/0x0000
Are those masks valid? Do I need to configure a queue explicitly
before passing these commands?
Thanks again,
Fargo
