Port forwarding on host interface

[Daniel Huhardeaux <daniel.huhardeaux@tootai.com>]

Hi all,

I would like to redirect an external port to another port on the same 
machine. I read on some documents that the kernel doesn't allow DNAT to 
127.0.0.1 so I ended up with following setup:

let's say I want to redirect 59000 port on my 1.2.3.4 public IP to 5900 
port on the same public IP *but a direct connection to 5900 port on the 
public IP* is forbidden. At this time my packets are marked for iproute2 
(2 ISP), mark 201 (isp1) or 202 (Isp2).

Has someone a tip for me? Is it true that forwarding to 127.0.0.1 can't 
be done?

Thanks for any hint.
