Web/Mailserver with one public IP

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

  • 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.
