I can't see Varnish Cache Server

I just installed CWP and i can't see "Apache Settings –> Varnish Cache Server". I was going to post about this and then i saw Varnish option under "Apache Settings –> Select Webservers" option. Screenshot: http://i.imgur.com/0UVrv0w.png

I changed "Apache only" to Apache & Varnish Cache" and then it asked to "Rebuild Virtual Hosts" and i did that. Now i'm not sure if there is anything else to do and why the options are not similar to this tutorial. http://wiki.centos-webpanel.com/how-to-install-varnish

Can someone please help me. How can i change ports etc. By the way, my sites are still working.

Thanks

Hello.

For changing ports you can use a config files and make changes manually.
