Connecting to Server via the Internet
I am experiencing some problems connecting to my clients server through the internet. I have installed Filemaker Server Advanced 8(Mac OSX) some time ago, and am using FM10(Vista) to connect remotely. I have forwarded port 5003 to the dedicated machine on a static IP that hosts the files, but am still having the message "Either the host is not available, or the file is not available on that host." At one point in time I was able to connect from outside the network, and I am not sure what they may have changed. My clients are able to connect within their network, and all permissions\priviledges, I believe are correct. I have done quite a few searches, but really don't even know where to start.
Any help would be greatly appreciated.
