We have an ASA5520 configured with a IPSec VPN, from any ADSL home/office our VPN clients can connect without any problem, but when we use our cellular phones in tetering mode (as an accesspoint) our VPN clients are impossible to connect. Same machines,same software, same operating system, same remote IP (ASA5520 external IP) only change Wifi connection (ADSL to cellular phone). The signal of cellular phones is not the problem we was doing the tests with different phones (IPHONE & ANDROID), different locations (all in spain) and differents providers (vodafone, orange and movistar) of internet by cellular phone.
We think that perhaps the problem is the licenses that our ASA5520 has... ¿Is our problem that our ASA do not have a license for this?
Our ASA5520 comes with this licenses:
