Can not connect with PocketPC and L2TP/PPTP

Post by jono » 22 Apr 2008, 10:00

This FAQ applies to:
  • Clavister CorePlus™ 8.70 and up
Unable to connect to a Clavister Security Gateway using L2TP/IPsec or PPTP from a PocketPC device.

The solution is to disable MPPE, i.e. only select None as encryption on the PPTP/L2TP tunnel.

This is not a good solution when it comes to PPTP as this is the only encryption available, but on L2TP there is still the IPSec layer that encrypts all data over the tunnel so the MPPE encryption on that is not needed.

Note: It is possible that this problem is solved in newer versions of the PocketPC OS.
