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?
