Failed QuickVPN Client connection

I am trying to connect a specific laptop to an RV-082. The connection is configured properly, as it works on other machines. This specific laptop is running Windows 7 Pro, Windows Defender for AV.

I have exceptions in the Windows Firewall, I have exceptions in Windows defender for the QuickVPN Client.

I have downloaded the latest version of the client.

I have confirmed IPSEC services are running, and that I can ping the router in question from the laptop.

The log indicates a failure to connect to the router at all.

Any ideas? any known issues with Windows Defender?

Thanks in advance

Re: Failed QuickVPN Client connection

To get a better idea of what is happening Id recommend...

1. Disable Windows Defender and test the VPN again. If it works, you know Defender is responsible.

2. Try this with the Cisco IPSec Client. If it fails, turn on the VPNClient logs (Logging>Enable, Log>Log Settings>3-HIGH, Log>Log Window)

3. You can also enable "debug cry isa" and "debug cry ipsec" on the router to see if any crypto packets are received

4. You can download a sniffer tool like Wireshark on the client and see if any vpn packets (udp 500, udp4500, tcp10000, esp50, etc) leave the physical or vpn adapter interface of the computer.
