How do,
Something I've wanted for a while, and not found (and don't know enough
to write myself) is a description of the path an IP packet takes through
the kernel, and where things like ipfw, ipfilter, natd, ipdivert, and so
on, take effect.
Something like (and keep in mind I've got no idea how accurate this is):
[in] <-- Interface the packet arrives on (e.g., fxp0)
|
|
V
[ipfw] <----------. <-- Processing by IPFW
|| |
|`----[divert]--' <-- Processing by IPFW divert rules
V
[...]
and so on. Anyone up for this?
