>Description:
With bridging enabled (fxp0/fxp1), and one_pass not set,
the following commands cause a kernel panic
ipfw pipe 1097 config
ipfw add 20197 pipe 1097 ip from 64.220.148.97 to any
Fatal trap 12: page fault while in kernel mode
fault virtual address = 0xc055064a
fault code = supervisor write, page not present
instruction pointer = 0x8:0xc0176d57
stack pointer = 0x10:0xc02cb860
frame pointer = 0x10:0xc02cb86c
code segment = base 0x0, limit 0xfffff, type 0x1b
= DPL 0, pres 1, def32 1, gran 1
processor eflags = interrupt enabled, resume, IOPL=0
current process = Idle
interrupt mask = net
trap number = 12
panic: page fault
>How-To-Repeat:
ipfw pipe 1097 config
ipfw add 20197 pipe 1097 ip from 64.220.148.97 to any
(consistently)
ipfw rules and kernel config to follow
(once I figure out how to get them off the "non-existent" machine)
