HTTPS traffic caching limitations

ESET Bridge does not support HTTPS traffic caching for ESET security products (and their versions) not listed above.

ESET PROTECT Cloud does not support HTTPS traffic caching—the required certificates are available in ESET PROTECT (ESET PROTECT supports HTTP/HTTPS traffic caching) but not in ESET PROTECT Cloud (ESET PROTECT Cloud supports only HTTP traffic caching).

ESET Bridge and ESET PROTECT Cloud support HTTP traffic caching for all ESET security products.


ESET PROTECT Cloud users with ESET Vulnerability & Patch Management

ESET Bridge blocks the Patch Management network traffic by default. ESET Bridge does not affect the reporting of vulnerabilities.

To enable the Patch Management network traffic, disable the Access Control List (ACL) rules in the ESET Bridge configuration file:

1.Open the ESET Bridge configuration restrict.conf.template file in a text editor:

oWindows: C:\ProgramData\ESET\Bridge\Proxies\Nginx\Conf\restrict.conf.template

oLinux: /var/opt/eset/bridge/nginx/conf/restrict.conf.template

2.Change set $valid_host 0; to set $valid_host 1;.

3.Save the restrict.conf.template file.

4.Restart the ESET Bridge service.

Disabling ACL rules allows the routing of all network traffic via ESET Bridge (ESET Bridge becomes an open proxy).
