Here are some of the considerations for using SSL VPN with sub interfaces (VLANs) in NGAF:

Compatibility and Configuration:

    General Support: Most NGAFs support SSL VPN with sub interfaces, but specific configurations and limitations may vary depending on the vendor and model.
    Thorough Documentation Review: Always consult your NGAF's documentation for precise guidance and configuration steps.

Potential Considerations:

    VLAN Configuration:
        Ensure correct VLAN configuration on both the NGAF and the interface.
        Verify that the SSL VPN configuration is aware of and uses the appropriate VLAN.
    Routing:
        Confirm proper routing between the sub interface and other network segments to guarantee VPN traffic flow.
    Access Control:
        Implement appropriate access control rules on the NGAF to manage VPN traffic based on VLAN membership.
    NAT:
        If Network Address Translation (NAT) is involved, consider its configuration and potential impact on VPN traffic.
    Performance:
        Sub interfaces can introduce some overhead, so assess potential performance impacts, especially for high-traffic VPNs.
        Monitor resource usage and adjust configurations if needed.

Best Practices:

    Planning and Testing:
        Carefully plan the SSL VPN deployment with sub interfaces, considering network design, security requirements, and performance implications.
        Conduct thorough testing in a non-production environment to ensure compatibility and functionality before deployment.
    Vendor Support:
        If unsure, consult your NGAF vendor's support for best practices and troubleshooting specific to your setup.

Additional Information:

    Specific NGAF Details: For more tailored guidance, please provide the vendor and model of your NGAF.
    Diagrams and Visuals: If you have access to network diagrams or configuration examples, sharing them could facilitate a more accurate assessment.
