IPad VPN (IPSec)

Hi all,


does anyone know if there is a general problem using Cisco IPSec over TCP with Optus 4G/3G?


Both IPad and MacOS are connecting but not packages are transferred. 


On a windows PC with Cisco client and transport over UDP, connections are not an issue.

Sometimes I need to quickly connect to work from iPad for support and troubleshooting and I don't have the windows laptop with me.


i have put the Optus SIM also in a HUAWEI 4G modem and an old unlocked Telstra 3G modem. Result is all the same. UDP is fine, TCP is not.


can specific APN settings make a difference?
