Replication on wireless networks - Urgent

I have an application that uses SQL Server merge replication. This application uses a settings.ini file to connect to the server/publisher. This file contains the publisher name, publisher database name, subscriber name, subscriber database name and conne
ction string.
This application works fine over the LAN and even WLAN. I want the application to identify the publisher from a server that's on the internet and my subscriber will be a mobile node. The problem is when I put the publisher in a public network, my subscrib
er doesnot recogonise it. I tried giving the IP address of the publisher along with the publisher name in the ini file. But this doesn't work. I do not have the source code of the application and hence cannot do anything inside the application to make it
recogonise the publisher.
Is there a solution for this? Please help.
Rammy,
hopefully using an Alias for the IP address will do it. Also you'll need to
consider the permissions and if you are using Windows authentication for the
agents, then this'll need to be of the pass-through variety. Here is an
article I used to set up VPN access:
