I am experiencing a few issues trying to establish a tunnel between our TZ 170 and our sister company's DrayTek Vigor. The tunnel seems to become active as and when it pleases but is inactive most of the time. In the log we get the following

IKE Initiator: Start Main Mode negotiation (Phase 1)
IKE Initiator: No response - remote party timeout
IKE negotiation aborted due to timeout
NAT Discovery : Peer IPSec Security Gateway doesn't support VPN NAT Traversal

When it is active we can't ping anything at either end and get the following messages in the log

Received packet retransmission. Drop duplicate packet
IPSec packet from an illegal host

Any help appreciated

It seems that a reverse-route (NAT transversal) cannot be set---this is common in different VPN devices with IPSec...
