First, let me describe the scenario : ( Using a different domain name. Example.com )
Our internal servers has FQDN names as : intranet.example.com ; sql1.example.com ; symantec.example.com ; proxy.example.com.......etc
Several web applications and web browsers use default home pages to : intranet.example.com and, inside this intranet site, there are a lot of links to other internal services using names for internal servers with the following sintax : apps.example.com
NOTE: ALL servers are internal..... None of them is outside the local network.
Now, the SWG is configured and blocking access to denied categories as pornography, weapons, shopping.. etc.
All was working OK for many weeks...until now !!!
Our external web site, http://www.example.com was categorized by IBM Deutschland Research & Development GmbH or in other words, the name for our internal domain was added to the Symantec Web Gateway Web Filter database in several categories.
The resulting scenario is that users, servers or internal applications are being blocked because our internal domain is categorized into one of the blocked category.
We are trying to remove, from the database, the name of our domain but has not been possible.
In the SWG, we are trying to Whitelisting some internal names as intranet.example.com and is working, but we have problems with others like : proxy.example.com ( The proxy for all clients ) and all the traffic from clients to internet, using the proxy server is being whitelisted, not reported, and allowed.
Whitelisting the internal subnet or IP addresses is allowing all traffic.
We understand that the internal domain should be different of the external web site... but this will be another long proyect.
Any help will be appreciated.
