How to access  vtiger crm with local lan IP and my  Public ip.

1. Login to router and port forward  public:80 ----- private:80
2. Login to vtiger via SSH and configure the both ip address in config file

 nano /var/www/vtigercrm/config.inc.php

$site_URL ='http://public ip/vtigercrm/';             

$site_URL ='http://private ip/vtigercrm/';

1. change the request.php file

 configure the request.php file - // comment the   "$this->validateReferer();" line

original 

        function validateReadAccess() {

         $this->validateReferer();

                // TODO validateIP restriction?

                return true;

        }

changes

nano /var/vtigercrm/includes/http/Request.php

        function validateReadAccess() {

//         $this->validateReferer();

                // TODO validateIP restriction?

                return true;

        }

I you now access it remotely from outside the lan, as well as internally. However, internally, I will still need to use the PUBLIC IP (as if I am outside the LAN)
