Hi,

I have the particolar network configuration that you see in attachment. I configured the SNAT
- External DMZ (Address) -> ANY : SNAT from Internal DMZ (Address)
to permit the ASG to connect to internet (see the thread https://community.sophos.com/products/unified-threat-management/astaroorg/f/55/t/44460).

I enabled Web Security in Trasparent Mode with Full Transparent Option.

For Internet Sites all works correctly.

If a client try to connect to "pearl.inogs.it" or "dru.inogs.it" or in general to an "internal" site, the browser show the "Impossible to find web site" page. Logs show the following message:

2010:03:09-15:11:25 astaro-gw-2 httpproxy[5022]: id="0002" severity="info" sys="SecureWeb" sub="http" name="web request blocked" action="block" method="GET" srcip="158.110.30.37" user="" statuscode="502" cached="0" profile="REF_DefaultHTTPProfile (Default Proxy)" filteraction="REF_DefaultHTTPCFFAction (Default content filter action)" size="2184" time="63227 ms" request="0xaf123028" url="pearl.inogs.it/.../NGO"

2010:03:09-15:11:45 astaro-gw-2 httpproxy[5022]: id="0002" severity="info" sys="SecureWeb" sub="http" name="web request blocked" action="block" method="GET" srcip="158.110.30.37" user="" statuscode="502" cached="0" profile="REF_DefaultHTTPProfile (Default Proxy)" filteraction="REF_DefaultHTTPCFFAction (Default content filter action)" size="2180" time="61768 ms" request="0xaf119f60" url="dru.inogs.it/.../NGO"

ASG categorizes correctly the sites but seem it blocks them, even though the "Non-Profit/Advocacy/NGO" category is allowed. Also the ASG doesn't show the usual "Category Blocked" page.

As workaround I put the IP of those sites in "Transparent mode skiplist" under "Advansed" tab of the Web Security configuration.

Where do you think the problem may be?

Regard,
Stefano

    I can't reach either one, and I'm not behind Astaro right now.  Your log lines don't have a reason= field, so the Astaro sin't actively blocking.

    I admit I'm still confused that your internal clients are on the external interface, but if it works, then it's obvious that you are not confused - and that's what counts!

    Cheers - Bob
