Right.  That sort of operation needs to be inside the kernel, in the
TCP (or UDP) / IP stack.

Think about it, but think hard.  One potential scenario is that
someone else (a "bad guy") with a wireless interface is (at some point
in time) close enough to join your network.  Now he is behind your
firewall, through no fault of the firewall's.  Security on a wireless
network is much more difficult than with a wired one.  It is nice,
though (I imagine), if you have a laptop or other mobile  device.
