How to set up a basic IPSec VPN tunnel on the IR900?
1. Go to [VPN > IPSec] > Click "New IPSec Tunnel". 2. Basic Settings: Enter peer IP address, local subnet (e.g., 192.168.2.0/24), and peer subnet. 3. Phase I: Select "Main Mode" (default) and set a shared key for authentication. 4. Phase II: Keep default IPSec strategy (3DES-MD5-96) or adjust as needed. 5. Save— the tunnel will negotiate automatically when both ends are configured.
