Hi there.

Curious if anyone has any experience with a lan 2 lan vpn with a draytek 2820 and an sg570. I seem to be having quite a bit of trouble with setting up the VPN.

basics covered such as different subnets etc.. correct passwords.

I am getting the draytek to dial in with IPsec VPN using preshared key.

on the SG570 I can see in the log:

Pluto[4486]: packet from xx:xx:xx:xx:500: Quick Mode message is for a non-existent (expired?) ISAKMP SA

I presume this is on the negotiation it is failing.

anyone know how to resolve this issue. I presume the SG570 is capable of connecting to the draytek.

Many thanks
