John,

 : First of all, let me warn you, im not a deep *nix dude, i''ve used
linux
 : for some time now but never at this level, so bare with me.

Flasher!  :)    {You meant "bear with me"}

 : I know my question most likely could be solved by reading the HOWTO,
 : however, i wanted to hear if someone knew a simple and fast solution
 : before i start reading 100''s of pages.

Traffic control isn''t terribly difficult, but it is conceptual.
I''d
recommend reading the LARTC HOWTO [1] and Stef Coene''s site [2].

 : It''s quite simple, i want to limit up outgoing traffic to 128kbit.
All
 : incoming should remain as maximum, only the outgoing should be
 : affected.

Well....since incoming and outgoing are required for any connection,
you''ll have to approach this from a different angle when you get ready
to
write some traffic control classifiers (tc filter).

 : Though, IF possible and not a MUST, i would like the intern network to
 : remain 100mbit.

No problem.  Take a look at the KPTD [3] to see that traffic control is
just about the last thing that happens to an outbound packet.

 : Anyone know a simple solution to this?

Simplest place to start would be the wondershaper [4], but you''ll need
to
tweak it if you intend to just cap the bandwidth available for connections
initiated from the inside.

Good luck,

-Martin
