	For us uninformed, could someone please reconcile these statements:

: 
: Has IP masquerading ever been impllemented in FreeBSD?


>Well, build the loadable kernel module that comes with
>Darren Reed's IPFilter and you can have NAT ( == IP Masquerading ).

:No.  IP "masquerading" is not RFC compliant.  This has been
:discussed to death.
:
:FreeBSD does, however, support proxy services, which is what
:IP "masquerading" claims to be.
:
:There is code in the current release of the firewall toolkit
:to do this, and there is Sock5.  Either one of these will let
:you do what you (apparently) want to do, but in an RFC compliant
:way.

	Being uninformed, my impression is that proxying via the toolkit
Socks is very application specific. It would be nice to have a more
general solution. Isn't masquerading more general ? Don't really want to
arrange apps specific proxy servers or hack in Socks support into each
Internet app (many/most of which one only gets in binary form)...

	Thanks.
