Hi
I work as a systems integrator and my boss is considering using Zentyal to replace Windows SBS in our corporate clients networks. He has recently asked me to configure a zentyal server on my home network as a Proxy Server as if it were for one of our already established corporate networks.
No problems installing it and gettting internet access, but connected devices can not get out to the internet when connected to the proxy server. I can't even ping the server successfully now that I have configured it as a proxy. I have done a search and tried following this guide:
http://doc.zentyal.org/en/proxy.htmlSet up is as follows:
DGN2200 Modem router connected to an ADSL line: DHCP disabled.
