SMB SSL-VPN: Tunnel all mode mobile connect disconnects immediately after launching the session on iOS 6 phone
With appliance configured with Tunnel all mode (no static routes), mobile connect client disconnects immediately after launched from an iOS 6 device. If we disable tunnel all mode and setup few static routes, the connection works without any issues. The following error will be seen in the nxplugin.txt file within the mobile connect logs:-
This issue is specific to iOS 6.0 devices as the empty IPV4 route (for tunnel all mode) dictionary is considered invalid. The fix is expected with our Mobile connect app update 2.0.x scheduled to be released.soon. Until the fix is available, the workaround is to add a static route on the appliance.
