I am afraid the hint to chapter 14 in the HOWTO was not very helpful.
It does not work, when combined with port forwarding.
(It does work when I run http on director with port 80, but this
is not what I want, because I need to run a different http on port 80
for other purposes on the director).

My ipvsadm is:
TCP rr
  ->               Local   1      0          0   

where is VIP (a director virtual address)

and is the director's real address

There is a http listening on port 81, which I can verify by accessing
it locally on the director itself.
