Hi all,
I'm working on a dual homed configuration. I have a
firewall that makes the routing.
the configurations is as follows:

public-ip-eth0 --\
                  FIREWALL ----> private-ip-eth2
public-ip-eth1 --/

I want to be able to have access to a server with a
private ip throughout a public ip and DNAT.
I understand that DNAT has session management so I did
as follows:

on the firewall I configured public ips as aliases
ie:
ifconfig eth1:0 200.62.53.226 netmask 255.255.255.240

then added in the firewall the following line:
iptables -A PREROUTING -t nat -d 200.62.53.226 -j DNAT
--to-destination 172.28.16.4

is there something wrong?
Why it doesn't work?

thanks in advance,
Carlos L�pez.
