Web/Mailserver with one public IP

imported_André
I tried it many time with different products, but I don't know if the following is possible. Has anyone any experience with the following:

I have only one public IP-adres (and I can't get a second, unless I take a second DSL account and I can't pay that). 

What I want is to make an DMZ with a web/mail/ftp-server and also normal internet on my 'home'-computer. Is this possible or do you need 2 or more public IP-adresses.

Thanks in advance,
André

    That is possible.  You just use NAT and forward the seperate ports for each service to the serving machine behind the firewall.

    Set up a DMZ and run DNAT from your public
    adress to your servers. From your internal net
    you will have to use MASQ.

    I do this very same thing.
    You need to set up a "network" with your DMZ server address. Use DNAT to change the Destination address from the external interface of your ASL to the DMZ server for what ever ports you want (25,110,80,etc).
    For your internal network (Eth0) you need to Masq your internal network to the external interface.
    Set up appropriate filter rules.
