VPN-connection between 1621 and Draytek 2300

[Henry]

Hello,

I have configurated our Lancom 1621 and my Draytek 2300 like explained in Document No: 0405.2415.1518.MBRI. When I initiate a connection from the Draytek to the Lancom a connection is made, but when I try to set up a connection from the Lancom to the Draytek I get the message
IKE or IPSec establishment timeout (initiator) [0x1106].
What could be wrong?
