Error: Remote access to the NetWeaver Administrator is forbidden. See SAP Note 1451753 for details.

Symptom

We have error Remote access to the NetWeaver Administrator is forbidden. See SAP Note 1451753 for details.

Solution

The URLs for NWA have a unique prefix and can be filtered out in the ICM on a rule basis.
In the profile file (we recommend the default profile DEFAULT.PFL), configure the following modification handler:
icm/HTTP/mod_0 = PREFIX=/,FILE=$(DIR_GLOBAL)/security/data/icm_filter_rules.txt

If you do not want to restrict access to the administration requests to certain clients, remove the lines from the file or turn the lines into a comment:
#if %{REMOTE_ADDR} !stricmp 127.0.0.1 [AND]
#if %{REMOTE_ADDR} !stricmp ::1
#RegIRedirectUrl ^/webdynpro/resources/sap. com/tc~lm~itsam~ui~mainframe~wd/(.)*$ /nwa/remote_access_error [QSA]

Then restart AS Java.
