I am trying to connect two routers over the internet using the Remote Gateway VPN Tunnel feature. Both routers have firmware version 2.39.2. I have configured the routers according the little information I have found on this topic. Below is my configuration on my routers Security/VPN page: VPN Passthrough: All enabled VPN Tunnel: Enabled Tunnel Name is the same on both routers. Local Secure Group: (Flipped on other router) Subnet 192.168.1.0 255.255.255.0 Remote Secure Group: Subnet 10.0.0.0 255.255.255.0 Remote Secure Group: I have Dynamic DNS and I have tried entering the IP and using the FQDN feature. Encryption: 3DES Authentication: MD5 Key Management: Key Exchange Method: Auto PFS: Enabled Using Pre-shared key that is identical on both routers. Have tried it disabled. Key Lifetime: 28000 Any help is much appreciated.
