Note: It's recommended to change default IPsec Key Exchange algorithms for higher security.

It can be configured in Windows firewall with advanced security --> (right panel) Properties --> IPsec Settings --> Customize IPsec defaults --> Key Exchange (advanced)

Trouble-Shooting

If VPN cannot establish, you may enable more protocols for authentication for a try. Go to Control Panel > Network and Internet > Network Connections, right-click on the connection of VPN to Vigor, and Properties. In Security Tab, enable both "PAP" and "CHAP" for Authentication, then click OK to apply.
