H there,

I got a problem, which I cannot solve on my own, so maybe someone can help.

I got 16 public IPs for my DMZ (orange) so I wanna use them for webservers.
This is how it looks: (addresses changed): to, netmask is 28, so subnetmask is is the router of the ISP, is orange on Endian.

The DMZ should be accessible from the Internet for everyone, but I do not know where to make changes at Endian configuration.
If I connect the servers directly to the router, everything works fine.

Someone who can help??

Is it correct that you use the same subnet for orange and red?
That will not work.

You have to use a different subnet for orange and assign your public IPs to the red.

Red and orange have different subnets and different addresses.

red is
orange is (addresses changed, of course)

the version of the Endian is 2.2 and I got 4 NIC inside. green, red, orange and blue (because of the hotspot)

But don't get this working...

You will need to use Source NAT.

Have a look at http://docs.endian.com/2.2/en/efw.firewall.html

Steve, would you be able to go into more detail on the actual setup here? I have a similar situation and cannot figure out how to configure SNAT to work for 1:1 private-to-public addressing. Thanks!
