Zimbra Proxy Server > Set Proxy Trusted IP Addresses

Set Proxy Trusted IP Addresses
When a proxy is configured with ZCS, each proxy server’s IP address must be configured in LDAP attribute zimbraMailTrustedIP to identify the proxy addresses as trusted when users log in through the proxy. The proxy IP address is added to the X-Forwarded-For header information. The X-Forwarded-For header is automatically added to the localconfig zimbra_http_originating_ip_header attribute. When a user logs in, this IP address and the user’s address are verified in the Zimbra mailbox log.
Set each proxy IP address in the attribute. For example, if you have two proxy servers:
zmprov mcf +zimbraMailTrustedIP {IP of nginx-1} +zimbraMailTrustedIP {IP of nginx-2}
Note:
To verify that X-Forwarded-For was correctly added to the localconfig, type zmlocalconfig | grep -i http. You should see zimbra_http originating_ip_header = X-Forwarded-For.
