Connecting to an SSN from an internal network

Hi

I have an Apache Web server running on a Solaris 8 box that sits on a SSN.

I have one desktop that connects to the SSN from the internal network and is recognised directly without using the gateway, all other desktops, laptops from inside the internal network connect to the SSN using the gateway. I want to allow more than the one desktop direct access to the webserver.

I have added additional desktops to the webservers /etc/hosts file but this does not seem to have any impact.

The reason why I am trying to do this is:
I have an application that restricts access to the website for members only (its not porn). When there is a lockout via the application for all users from our internal network (the users are locked out by a shared external IP address) only the desktop (using its internal IP address) which has direct access to the webserver can then acccess the administration panel of the application. I want more than one user to be able to access the administration panel in the event of a lockout.

Any suggestions as to how to remedy this problem?

Thanks in advance.
