Hello,
I need to setup a Site-to-Site VPN the likes of which I am not familiar with. The details I have been given are to take place upon a Draytek 2860n router at my site. The details are as follows:

IPSec configuration
Session Key Setup / IPSec Phase 1 (at lifetime 24 hours)
Autentication: SHA-256
Encryption: AES-256
Key Exchange operation security: DH-roup-14 (2048 bit)

Tunnel Transformation / IPSec Phase 2 (at lifetime 1 our)
AH-Authentication: none
ESP-Autentication: SHA-256
ESP-Encryption: AES-256
PfS: DH-group-14 (2048 bit)
Preshared Secret: TBC

Primary VPN ENDPOINT: IP Address
Fallback VPN ENDPOINT: IP Address

Primary REMOTE NETWORK: IP Address
Fallback REMOTE NETWORK: IP Address

Can someone please assist me?

Many thanks….

Make sure you have SYSLOG configured, so you can see what's happening!

Thanks for the quick response. I did look at that Draytek article earlier but could not see where I would specify the particular setting I must enter. That's why I discounted it. Am I missing something?

The router at the other end is a non-Draytek router.
