This procedure is only relevant for users who have chosen to access the combined IGSS/Web server via a modem connection, i.e. an Internet Service Provider is not used. The advantage of this solution lies in the security it provides by preventing access to the IGSS/Web server through the Internet. Briefly described, third party gateway software for WAP services is installed directly on the IGSS/Web server instead of being located on an Internet Service Provider’s own WAP services gateway server. This means that attempts to access the IGSS/Web server by unauthorized users become more difficult because the IGSS/Web server with modem access is not directly visible on the Internet.
