I have same problem (ros 6.14, iOS 7.1.1). Guys on OpenVPN forum think it is a iOS app problem but I think is maybe something MT guys should check because absolutely same configuration with CentOS instead of Mikrotik works fine. Any ideas?

Note: Tried same config from Mac and PC. Works fine both with Mikrotik and CentOS.
