Re: Incorrect access detected, this server may be accessed only through "http://192.168.2.2:8181/moodle" address, sorry. Please notify server administrator.

This is what I have in config.php and I changed the the Local IP to the Real IP I have, 

$CFG->wwwroot   = 'http://192.168.2.2:8181/moodle';

$CFG->dataroot = 'C:\\wamp\\moodledata';

$CFG->admin     = 'admin';

changed to 

$CFG->wwwroot   = 'http://REAL IP:8181/moodle'; (Real IP) and the Port.

$CFG->dataroot  = 'C:\\wamp\\moodledata';

$CFG->admin     = 'admin';

 and this is the router configuration for the port forwarding.. but it shows the internal network interface for the TMG, I believe all the configuration on the TMG and the router is fine, because I reach the Apache Server from outside, but when I try to access the project (Moodle) on the apache I get the redirect page.
