Hi
I have a bit of a strange one here ..
I have managed to get the tunnel up and working and we are sending data via the tunnel from our Cisco VPN router to the Draytek and onto the clients server. (they , the client, have acknowledged that they are recieving and sending packets back to us).
But, we never see any returning packets at our VPN tunnel endpoint. When we send I see the encrypted packet count go up , but the packet decrypt remains at zero, this is using show crypto ipsec sa | begin x.x.x.x.
We do have other working VPN solutions, but this is the first connecting to a Draytek. The ACL's are matching, and they have NAT turned off. The routing is fine or else the tunnel would not come up as are all the tunnel parameters, else our packets would not arrive at their server.
I just cannot fathom out why we are not seeing any return packets ....
They say they have a route back to us .....
Anyone come across a similar problem like this ?
thanks
Mike
