When HTTP/S proxy is enable Google Apps Mail (Gmail) and Chat fail, we have configured the exception but it does not allow Gmail and Gmail chat to pass. Does any one have a proxy configuration to make this work?
... SSL-Scanning is enabled, Nothing enabled in URL filtering, packets are not being dropped.
ssl scanning is not playing nice with google chat? Do you have the other ports setup correctly? Did it work in older versions of astaro? You won't see packets being dropped on ssl connection if proxy is handling it.
