Changing VirtualHost IP

Hi,

where in Virtualmin/Webmin I can change IP address to get in /etc/httpd/conf/httpd.conf THIS: VirtualHost *:8080 instead of original generated data: VirtualHost 83.11.x.121:8080

I use Centos 7 and the latest Virtualmin, I need this for Varnish 3.

I can edit manually all IP in /etc/httpd/conf/httpd.conf VirtualHost but this is no good idea if you use Virtualmin.

Please advise

I updated this topic because it was broke, I added this character: < and some data was missed. So could you read a topic again please and try help…
