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?
