We have converted (= opened) our multi file fmp12 system to FM14 and published it on FMS14. Works without problems over LAN. However, when we open it directly over WAN we get countless authentication dialogs. When opened via VPN these don't occur.
In earlier versions of FileMaker (12 and 13) this problem never occurred. We have set FMreauthenticate from 0 to 10, but that doesn't help.
