Currently our Zentyal server is public-ally visible on eth1 through a public / external static IP and this is working perfectly.
We need to use eth0 as an internal Gateway / Router to our inside computers. We are not familiar with how best to configure this and need an expert in this area.
We require that you have previous Zentyal experience as this MUST NOT BE configured from a command line. Instead it must be configured within Zentyal UI as Zentyal overwrites any manual configs.
The attached Diagram makes clear (I hope) the configuration we need to put in place.
Furthermore, it is VERY important that we understand the exact configurations you changed in Zentyal as we must duplicate these changes for our client that you are making for our business.
I do not wish to pay for you to learn. I mean no offense by this. I am looking for someone who can teach us to resolve this and not learning as they go.
