This article explains the reason for the warning message indicating that a Web Filtering EWF license is required when configuring web filtering on SRX2300 devices.
A warning message similar to the following is observed during configuration:
Warning: requires 'Web Filtering EWF' license
The SRX2300 platform includes the wf_key_ng_juniper license by default, which supports the next-generation (NG) Juniper web filtering solution.
However, when configuring legacy web filtering using:
type juniper-enhanced
The system expects a Web Filtering EWF (Enhanced Web Filtering) license, which is not included by default on SRX2300. This mismatch results in the warning message.
To resolve this warning, use web filtering configurations compatible with the default license on SRX2300:
juniper-enhanced
Alternatively, if legacy web filtering is required, ensure that the appropriate EWF license is procured and installed.
