Configure proxy settings for the agent

You might need to configure proxy settings if an agent is having trouble accessing the Internet. The proxy is supported on Windows, Macintosh, and Linux operating systems.

Select Menu → Policy → Policy Catalog.
From Products, select Trellix Agent → Repository. Click Edit to update a policy.
Note
For ePO - On-prem 5.9 or earlier and McAfee ePO Cloud, select Trellix Agent from Product drop-down list and Repository from Category drop-down list.
From the list of policies, select any policy listed on this page other than Trellix Default.
Click Proxy.
Select your preferred option:
- Select Do not use a proxy if your agent does not require a proxy to access the Internet.
- Select Use Internet Explorer settings (For Windows) / System Preferences settings (For Mac OSX)/ System environment variables (For Linux), then enable Allow user to configure proxy settings.
  Note
  On Linux systems, you can add or modify the proxy information in the /etc/ma.d/ma_environment.conf file. Restart the Trellix Agent services once you add or modify the proxy information. The proxy information in a ma_environment.conf file can be as shown below:
```
http_proxy=<proxy_url>:<proxy_port>
HTTP_PROXY=<proxy_url>:<proxy_port>
https_proxy=<proxy_url>:<proxy_port>
HTTPS_PROXY=<proxy_url>:<proxy_port>
no_proxy=<localhost>
all_proxy=<proxy_url>:<proxy_port>
```
  To configure the proxy settings for Trellix Agent, and to allow continuous communication with ePO - On-prem when a user session is logged out, use the netsh command to set the proxy.
```
netsh winhttp import proxy source =ie (if the proxy already configured in IE)
or
netsh winhttp set proxy <proxy>:<port>
				
```
- Select Manually configure the proxy settings if you need a proxy other than Internet Explorer, and configure the following settings:
  1. Select a form for the address of the source HTTP or FTP location where the agent pulls updates.
    DNS Name
    IPv4
    IPv6
  2. Type the DNS name or IP address and port numbers of the HTTP or FTP source. If appropriate, select Use these settings for all proxy types.
  3. Select Specify exceptions to designate systems that do not require access to the proxy.
  4. Select Use HTTP proxy authentication and Use FTP proxy authentication, then provide a user name and credentials.
Click Save.
