Thilo,
Did you ever receive an answer on this question?
Also--a question of clarification....
  Do you mean that only UID 1001 should be allowed to bind to 192.168.1.11
  for outbound packets?
If so, then, why not try this:
  iptables -I OUTPUT -o $OUTDEV -m owner ! --uid-owner 1001 -j DROP
Is that what you wished to accomplish?

 : Hello,
 :
 : I have a machine with several ips. My goal is to only allow access to one ip
 : for a certain user. for example 192.168.1.11 may only be used by UID 1001
 :
 : I have found in the man page for bind following errno numeric:
 : > EACCES The address is protected, and the user is not the super-user.
 :
 : Is it possible to restrict access to certain ips to certain uids?
