I have a Smartermail 15.4 server behind NAT, with public IP on the firewall and local private IP on the server LAN card (pretty common configuration, I presume).

 

When I try to open pages that contains generate dimages (like report pages) the images result missing bacuse the image address used is the LOCAL PRIVATE IP instead of FQDN or Public IP (example: http://192.168.1.161/TempResourceHandler.ashx?file=dacdb68015a449dfa3f713cb8186811a.png ).

 

There's a way to workaround this issue?
