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. =20
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?
