Hi,

Before adding those iptables rules add following two command:
Next load the iptables rules and try out ftp. It should work now. Let me know if you need more help.

Yes it's working now
tanx for your help!
what's these commands mean?

FTP is a complex protocol when you use iptables (or nat via iptables) you need to use ip_conntrack_ftp. It does help or it is ftp connection tracking helper. In short if you want to use passive ftp you need to use this kernel module.

Above two modules enables connection tracking. Please read my previous tutorial for more info:

ok thanx!

by the way, i'm trying to set up an smtp relay to my exchange server on this machine, I tried sendmail but it's too difficult to configure , so i think i will use postfix

do you know any site talking about such config?

Edit /etc/postfix/main.cf and add/append line

Restart postfix. Here are few tutorils:
http://www.postfix.org/docs.html

If you want a book try - Setup and Run a Small Office Email Server Using Postfix, Courier, Procmail, Squirrelmail, Clamav and Spamassassin, see my review:

what i want is to realy all the mail coming from my mail server to this machine (where i run postfix) and it will send it trough internet,

and vice versa, all the mail coming from internet will be rerouted to my mail server

is it possible with postfix? what can i do?
