You can use Open Remote with FileMaker on your lap top to remotely access your database, but you still must setup portwarding for your internet router so that it works correctly. Once portforwarding is set up correctly, you can launch filemaker, select open remote and then type in the IP address of your internet router to gain access to your database--provided it is open on your server.
You are on your local network
All your computers have 192.168.x.x as a local network IP address.
So if your computer is 192.168.x.102 it can see your FMP server at 192.168.x.104
Because it is on the same local network.
If you go to Starbucks your local IP address may be 192.168.x.102
BUT it is the Starbucks local network not your own local network, it can see only the local Starbucks network.
You need to navigate the Starbucks router, the internet DNS severs, your local modem/router (Cable/DSL), your local router and your local FMP server.
Your computer's local Starbucks IP (you don't care)
Your Starbucks local router (you don't care)
The internet DNS Servers (you may care)
There are two ways you can access your FMP database
The database is hosted by a FMP hosting service that gives you a http access address
You are hosting the FMP database that is accessed by your Cable/DSL ISP address that may be constant or variable.
If you are hosting the FMP on your local network, YOU MUST portforward the request from your router to the hosting computer.
IF your router IP address is 220.127.116.116 it MUST have port 5007 forwarded to your local computer IP address 192.168.1.103
THUS a rerequest from FMP on your computer in Starbucks for a connection at 18.104.22.1686:5007 (a FMP remote host request)
Will go to your router at 22.214.171.1246 through port 5007 to the computer at local IP address 192.168.x.102
thank you both for the great answers. I am going from ATT to comcast as our service provider in the next couple of days so I will wait until I have the new provider in place before I attempt again. Thanks David for the great details, I am sure it will make this easier.
