# Find VPN issues

The SMC Client has automatic VPN validation that checks the settings you have selected are compatible with each other.

##

When you configure the policy-based VPN, the validity of the VPN is automatically checked based on settings in VPN Profile elements, VPN Gateway Profile elements assigned to gateways in the VPN, endpoint identity information, and gateways certificates. If problems are found, they are shown in the Issues view. While useful in many cases, the automatic check does not detect all problems, especially regarding external gateways or interference between several separate policy-based VPNs.
