Hi,

need some ideas, how to deal with this problem:

VPN client periodically (ie about every 20 sec) disconnects after ... error connection closed ... and automatically reconnects.

Client Conneted using UMTS/HSPA to internet, connection stabel.

In the VPN Servers log it seems that there are problems with the alive message.

Edwin, If I understand the working of G3/UMTS/HSDPA it recycle the IP much faster then the landlines.
This happens because your changing everytime of transmitter antenna. So the connecion will be lost.
I have seen it with mobile phones/tablet who connect to Kerio Connect thru a Kerio Control. Same devices but several public IP's.

So maybe this is the problem.
