The connection using IOS seems a little glitchy. I'm not using static address but was still able to connect if I ignored the wrong address produced by FMP and simply used the one the device says it has. Not sure what is happening in your deployment, maybe something as simple as a manual addressing error. That said, you shouldn't have to enter the address manually, if you have properly set up the server, it should populate as a server option on your client. If not, try resetting your router.
Best I can do,
Thank you for the post.
"iMac (OSX 10)"
Does that mean you are installing FileMaker Server 13 to Mac OS X beta software?
The following knowledge base article lists all the tested and supported operating systems for FileMaker Server 13:
"Operating systems not listed in the table" in the article "above have not been tested and are not supported."
Thanks for your replies. I actually was able to solve the issue finally by shutting off my Mac's wifi and forcing the use of the cat 5 connection. Even though the mac said it was using the correct static IP before, somehow with all other options shut off it seems to be working after reboot. I don't know enough about the topic to offer any insight on why this worked but I'm content not to poke the bees nest.
