I`ve published a few internal services and websites using the Web Application Firewall in UTM 9.2, and this have worked well except for publishing Outlook Anywhere against Exchange 2010 SP3. I used the following guide to configure the publishing of Outlook Anywhere (using Basic authentication):
https://sophserv.sophos.com/repo_kb/120454/file/Configuring%20UTM%20firewall%20for%20Exchange.pdf I use https://testconnectivity.microsoft.com for testing the published application.
From the testconnectivity.microsoft.com website I get the following error when testing Outlook Anywhere: RPC_S_SERVER_UNAVAILABLE (0x6)
In the Web Application Firewall Log I see the following entries logged while performing the test:
Are there any known issues regarding publishing Outlook Anywhere with Sophos UTM 9.2?
If not, do you have any ideas what might be the issue in my setup?
ID32217 9.203 Outlook anywhere behind the WAF didn't work
------------------------------------------------------------------------
Description: If an Outlook Anywhere is behind the WAF and the test tool
from microsoft (https://testconnectivity.microsoft.com/)
is used you will get some errors in the output from the
test tool.
But there is no issue when you use the WAF config for the
outlook client. Everything works fine and the error from
the test tool can be ignored.
Workaround: Independent from the error in the output of the microsoft
test tool you can use the OA config for outlook on the
clients.
I would suggest to add the related error messages to the known issues item in order to make it easier for others who struggle with the same problem to find this information. I searched quite extensively on the error message without finding a reference to the "Sophos UTM v 9, Known issues" page.
