I have a Microsoft Access desktop frontend app that is connected to an SQL Server Express backend on the same PC. This works properly with the caveat that every user with the frontend app must connect to the LAN. I would like to move the backend online so that users (employees) will be able to use the frontend from any location; all they'll need is an internet connection. I will also want to create a few web pages that clients can use to access some of the data. The clients won't be writing any data; just reading.
Presently, I have a copy of the backend hosted online at HostGator. However, there is a requirement to whitelist every IP address that wishes to access the database. The problem is the users of the frontend desktop app will have their respective internet IP addresses assigned via DHCP and so I can't whitelist in advance. In testing, the Access app connects fine when I whitelist but doesn't connect if I use an IP address that isn't whitelisted. I don't mind whitelisting to be able to use SSMS.
Is what I am trying to do possible with a webhost? If not, what services do you recommend?
PS: I was able to create an ODBC connection on HostGator but the server address is 127.0.0.1 - this is a local host. Is there anyway to use this connection from withing Access?
