In my virtual host file ispconfig3 /etc/apache2/sites-available/site.nl.vhost I changed the first line to LISTEN 96 <VirtualHost 192.168.1.16:80 *:96 > so that apache will serve on port 96 also but the changes are overwritten constantly. where can I better put this directive.
This can not be changed for a single vhost. But you can change the master template for all vhosts in /usr/local/ispconfig/server/conf/
