Running Ubuntu 16.04 with Webmin 1.860 Virtualmin 6.01 gpl-3, we have a number of virtual servers defined. A few of these have websites. For most of these websites, when using the Preview Website function we see: Connections to IP addresses not on this system are not allowed : xxx.xxx.xxx.xxx
We do not see a difference in configuration between the sites we can preview and those we can't.
Could anyone suggest the cause of the problem - or how we might go about diagnosing it?
I noticed an older thread that concluded that adding addresses to /etc/webmin/virtual-server/localips would solve this, but this cannot be the case as localips is, apparently, rewritten automatically. Possibly if we knew how localips is written then that would give a clue of how to make the websites reviewable.
Thanks for your help!
