Well, I have actually 5 public ips I could use.
So I created 4 virtual interfaces (1 public ip is for the firewall), and I thought I could associate 2 publics ips for lan2 and 2 for dmz.
This way, I could have a NAT rule 109.xxx.xxx.3:80 -> 192.168.2.2 and 109.xxx.xxx.4:80 -> 192.168.2.3.
Isn't this possible ? If not, how can I use more than 3 public ip (the firewall, lan2 and the dmz) ?
But now nothing is working anymore. I have a fiber modem and I wanted to configure it in bridge mode. So I had to activate the pppoe on my firewall instead of my modem... and now everything is f%รง"* up
