Ok I feel dumb, but I cannot get a simple NAT to work...and its probally just a step that I am missing.
Ok here is my configuration:
Global:
Gateway: 216.x.x.97
First Nic: (internal)
IP: 192.168.1.1
mask: 255.255.255.0
Second Nic: (external)
IP: 216.x.x.101
Mask: 255.255.255.248
Aliases added to external Nic:
216.x.x.98
216.x.x.99
216.x.x.100
3 of my computers in my setup all run httpd,ssh,httpd,pop3 and smtp. I want all of them to be natted.
So I made a Service Group called web_services that contained all of the predefined services that came with Astaro 2.016.
After this I went to Networks and defined each of my internal computers:
192.168.1.2 natasa
192.168.1.3 natasb
192.168.1.4 natasc
216.x.x.98 natasa_ext
216.x.x.99 natasb_ext
216.x.x.100 natasc_ext
First of all It would only let me use the netmask 255.255.255.255 for these; it gave errors when I tried to tell it 255.255.255.0.
After this I went DNAT and created the following rules for each service. This confused me because I thought that it should have listed service groups to select from but it didn't.
Example:
natasa http natasa_ext http
Anyway its not working and Im totally confused....I have setup firewalls before and its usually just these steps above...what am I missing. Can someone with the same setup go through a small walk through of how they set this up?
BTW I want the following to happen. I want the computers listed below to run httpd,ssh,httpd,pop3 and smtp:
192.168.1.2 to be 216.x.x.98
192.168.1.3 to be 216.x.x.99
192.168.1.4 to be 216.x.x.100
