Which network topology (NAT & port forwarding, 1:1 NAT, bridge)?

Hello,

i#m unclear about how to deploy the server into our network.

We have a running FreePBX server, where i was told to use a 1:1 NAT.

In icewarp, there is not only SIP (which is a NAT  adversar) but also  XMPP and FTP, which all don't like NAT.

We have softphones and harphones in LAN and also with roadrunners (Smartphones, etc.) and we need authentication against a inhouse (LAN) AD-controller.

So my question is, which network topology to use?

If icewarp would include additional security functionality, like a "learning" firewall, something like "fail-to-ban" or other software i would choose a bridge topology and put the icewarp server directly in the internet (with public IP) but i#m unsure if this is really a secure thing.

So, what is the recommendation for the network topology?

  One question,

  i have written this post 1month ago and it is not even approved into the forum.

   

  Is this a sign of your support quality in general?

   

  Where should i post my questions? In ServerFault Forum it seems to fit better. Yes?
