Can't access localhost from Internet using multisite subfolders

Hi All,

Goal:

• I wish to develop on my localhost using multisite subfolders.
• I need my team members to be able to access my sites from the internet.

I do assume this is actually possible. Virtual hosts maybe that map to correct folder? I’m still learning the ropes…

Problem:
I can access both front and back ends of primary and secondary sites from my internal machine. For example:
Primary site:      127.0.0.1/wordpress
Secondary sites: 127.0.0.1/wordpress/s2
                         127.0.0.1/wordpress/s3
                         ...etc

But whenever I try to access from external machines on internet using
110.22.25.35/wordpress
110.22.25.35/wordpress/s2
…etc
wordpress redirects to 127.0.0.1/wordpress on the external machine
Of course, since the external machine has nothing running there it fails to load. Note that secondary sites, eg 110.22.25.35/wordpress/s2 are also redirected to 127.0.0.1/wordpress, not 127.0.0.1/wordpress/s2

LocalMachine Directory Structure (partial):
C:\xampp
C:\xampp\apache
C:\xampp\mysql
C:\xampp\apps\wordpress

MySQL DB from phpMyAdmin (partial):
bitnami_wordpress/wp-options/siteurl = http://127.0.0.1/wordpress
bitnami_wordpress/wp-options/home  = http://127.0.0.1/wordpress

Configuration (partial):
C:\xampp\apps\wordpress\htdocs\wp-config

/** MySQL hostname */
define('DB_HOST', 'localhost:3306');
...
/* Multisite */
define( 'WP_ALLOW_MULTISITE', true );
define('MULTISITE', true);

define('DOMAIN_CURRENT_SITE', '127.0.0.1');
define('PATH_CURRENT_SITE', '/wordpress/');

C:\xampp\apps\wordpress\htdocs\.htaccess

# BEGIN WordPress

C:\xampp\apps\wordpress\conf\httpd-prefix.conf

Alias /wordpress/ "C:/xampp/apps/wordpress/htdocs/"
Alias /wordpress "C:/xampp/apps/wordpress/htdocs"
Include "C:/xampp/apps/wordpress/conf/httpd-app.conf"

C:\xampp\apps\wordpress\conf\httpd-app.conf
I’m pretty sure this gets overwritten by C:/xampp/apps/wordpress/htdocs/.htaccess? (so no need for rewrite rule)

<Directory "C:/xampp/apps/wordpress/htdocs">
    Options +MultiViews +FollowSymLinks
    AllowOverride FileInfo Options
    <IfVersion < 2.3 >
    Order allow,deny
    Allow from all
    </IfVersion>
    <IfVersion >= 2.3>
    Require all granted
    </IfVersion>
</Directory>

C:\WINDOWS\system32\drivers\etc\hosts
127.0.0.1 localhost

Other Info:

• I know the gateway (110.22.25.35) is correctly forwarding because non-WP pages are correctly displayed
• I figure i need to somehow stop wordpress mapping external requests to 127.0.0.1, but don’t know how to do this without breaking everything.
• Perhaps using VirtualHost, ServerName or ServerAlias somehow?

Any ideas would be greatly appreciated.
