3 NICs configuration with DMZ and multiple IPs

drhonk
Hi guys,

First of all.. let me say that astaro is really a great product.  [:)]

Here's what I have, SDSL with IPs 123.123.123.0 netmask 255.255.255.224
My provider assign the WAN side of the router to be on a different IP and using 123.123.123.1 to be my LAN side of the router which also my default gateway. I've setup ASL between my router and my switch as follow:

eth0 (Internal) = 10.3.0.1
eth1 (External) = 123.123.123.2
eth2 (DMZ) = 10.2.0.1
Default Gateway = 123.123.123.1

Now .. I need to put several servers in the DMZ with similar services such as SSH, SMTP, POP, HTTP,etc.

I've read almost every thread concerning this problem, but after trying .. nothing works. I tried using Proxy ARP, but still nothing. Could you guys tell me what kind of setting I should use to DMZ to work. Also what do I have to change in every server in the DMZ ?

    Thanks for that info,

    but I will need to allocate several IP from 123.123.123.x/255.255.255.224 to be accessible to the internet from DMZ. If I do like the one in that thread you shows me .. basically the IP of that server behind DMZ would accessible using the IP address of my external ethernet right ?

    What if you have mail server with SSH using 123.123.123.5, web server with SSH using 123.123.123.6, ftp server with SSH using 123.123.123.7, and all in the DMZ. What should I do if I want those IP to be accessible from the internet ?
