You guys are absolutely right, i am very sorry if you feel that my "Its pretty easy" are offending the spirit of the forum/technical stuff.
I just started using Zentyal for about a month ago and ive tried out the different features and i really like what i see.
I am a network administrator, i currently hold a CCENT, CCNA, CCNP, CCNAS and CSSA, and i have 10 years of experience with infrastructure management, but primarily focused on Windows and Cisco. Therefore i have not looked at the deep technical details of all features, i have an understanding how proxy work but not the deep details.
I already ordered the Zentyal manual and i am also going to get certified, so i really try to apply my self because i really wanna learn.
I have always loved Open source and Linux, and when i came across Zentyal it seamed like the perfect solution for me.
I agreed that we have to find out why it works for me, to clarify what happens since the Squid documentation clearly states the HTTPs should not work.
My setup atm.
VDSL Modem -> Cisco ASA firewall -> Zentyal inside VMware ESXi and Clients. The Cisco ASA are the gateway/firewall, Zentyal running DNS, PDC and firewall(yet i am not using it as a firewall)
I am not using Zentyal as a gateway yet(waiting for hardware), just turned on the Proxy feature and set my Clients proxy settings to point on the Zentyal server. On the Clients i enabled "Use the same proxy server for ALL protocols"
When i access facebook via. HTTP i get a page "Access deny" when i use the HTTPs i just get "Page not found".
Sorry for the bad English
