Handoff fine to 4G but not back to WiFi

markn62 · Post by **markn62** » Wed Nov 11, 2015 2:57 am

Any suggestions why iOS9 OpenVPN Connect will hand-off from WiFi to 4G but not from 4G to WiFi? The following shows the 4G connection followed by detection of WiFi then repeated attempts to connect to WiFi using the last public IP rather than a private IP. After which OpenVpn gives up and disconnects leaving me to restart next time I leave the WiFi network. I manage the VPN server on the WiFi network.
