From a remote location, via someone else's WiFi or via 3G, click the Open File Browser... button.
Click Add Host...
Put in either your static IP address (as set by your ISP, not the local one on your LAN assigned to your FMS) or the domain name that gets you there, if you have one. Do NOT put the :5003 on the IP address or domain name. For example, mine is 188.8.131.52 or lab.troymeyers.com. My FileMaker Server machine is at 192.168.1.111 on my LAN, but that's not the IP address you should use.
There is a box for Host Name also, and you can put something logical there like "Brian's FMS as Remote".
Now this will show up in the Favorite Hosts list.
Try connecting by clicking the name or IP address in that list. If all goes well then you should be presented with a list of filenames that you have granted access to via the fmapp privilege.
You can try mine too (use IP addr or domain name) but you won't be able to open the files, just see them.
If this doesn't seem to work, then make sure your router/firewall is set to pass port 5003, and that port 5003 coming from the WAN is mapped to port 5003 on the local IP address of your FMS machine.
Oh, I'm saying FMS meaning FileMaker Server, but I guess you are just hosting the databases by having sharing on, using FMPA, that's fine too, just use the local IP address of the machine running that.
I have a variation on the problem. My server hosts a web site on port 80. When I tried to turn on Instant Web Sharing in FMP, it tells me there is a port conflict and offers to let me change the port for FMP. I chose 8080. Everything is fine when I try to connect through a browser (Safari) as long as I add ":8080" to the URL. This works as well from iPad.
But when I use Filemaker Go 1.2 from iPad, it fails, telling me that there are no databases available. The host is "old.url.net:8080/database.fp7". Is there a different notation? Have I missed a step?
I didn't express that right. The host is "old.url.net:8080" and attempting to connect invites me then to enter a file name, which is "database.fp7". FMGO displays it as in the previous post. Then it says: The file "database.fp7" could not be opened. Either the host is not available, or the file is not available on that host.
I think there's a bit of a misunderstanding as far as how FileMaker Go connects to hosted databases. Instant Web Publishing is a protocol that's intended to allow access to a database via a web browser. FileMaker Go uses the FileMaker Network Sharing protocol (same one used for a FMP to FMP or FMP to FMS connections) which communicates over port 5003. So to access your hosted database via Go, you'll need to verify that FileMaker Network Sharing is enabled (under the File -> Sharing -> FileMaker Network Sharing menu) and access it using just the host name (specifying :5003 is not needed).
Please let me know if you'd like any further clarification.
Thank you, TSBear. It works! A bit of misunderstanding? You're very generous.
Troy, How do you get the static IP address. I've gone through the RUN>CMD>IPCONFIG but the address shown is the 192.168........ thingy.
I can't see one resembling yours (184.108.40.206). When I put yours in I can see your file list.
I also went to http://whatismyipaddress.com/ but the one given for my IP didn't work either.
TedN, the IPs 192.168.*.* are reserved for private networks of machines that cannot be reached directly by others out in cyberspace. For example, in my situation, I have DSL service and my modem+router talks to the internet on a public address, but it talks to my computers on that private network. My public address is assigned by my DSL provider and is subject to change at any moment. They would gladly give me a permanent (static) IP address if I weren't too cheap to pay for it.
I use the free service DynDNS to keep my domain connected to my public IP address, even though it's a moving target. You don't need a static IP, you need a domain, say, TedN.com.
OK. My IP provides me with some webspace and I've placed the FP file in there. I can open it on my iPad through the browser (a notice appears asking if I want to open it in FM Go).
I can't open it directly through FM Go though. I get the notice saying No files available and asking me to Enter Filename. When I enter filename I get a message saying file couldn't be opened. Either host or file is not available.
See TSBear's post above. Turn on FileMaker Network Sharing under the File -> Sharing -> FileMaker Network Sharing menu.
Still no luck connecting.
I went to File>Sharing>FileMaker Network
Network Sharing is On.
Network Access to File is All Users
The only anomaly is at the very top of the screen where it shows the file it says:
FileMaker Pro - [03.56-06-5]. The file is actualy 03.56-06-5. Not sure what the  means. There's only one file there.
I should clarify. I'm able to see the file name anomaly when I open it via my browser.
It sounds like you have the file hosted through a normal web server, not through FileMaker Pro. If this is the case, you'll be able to download the file onto the device but you can't access it as a hosted file. Only files opened in FileMaker Pro/FileMaker Server with the FileMaker Network Sharing feature enabled can be accessed remotely using FileMaker Go.
If you're unable to access it using the external IP address, try testing it when connected to the same wifi network as the host. If the host/file shows up there, then you may need to setup something called port forwarding on the router. You can find more information this process here:
I think I'm going in a bit of a circle here. I have FileMaker Pro on my computer and FileMaker Go on my iPad. What do I need to do to upload and download files/data between the two.
I initially thought I had to put the FileMaker Pro file on a website, which I've done. But it appears from what you're saying that, that is not so.
Are you saying that I also need to get FileMaker Server?
I've set port forwarding at 5003 for both TCP and UDP.
I can't see my computer or the web space provided by my my ISP from FMG on my iPad.
I've also placed the FMP file at a totally independant website (nothing to do with my ISP) and I still cannot see the file from my iPad.
I must be missing something. Any ideas?
