The solution was to check if the resource is L3VPN resource and if not, it is not required to assign virtual IP. Another solution was to check if Sangfor SSL VPN CS Support System VNIC has been successfully installed and if there are other VPN network adapter or unknown adapter. If yes, get approval from the client to uninstall the driver

It sounds like you're encountering connectivity issues with VPN users when NGAF (Next-Generation Firewall) is placed in between the VPN users and the rest of the network. There could be several reasons for this behavior. Here are a few troubleshooting steps you could consider:

    Routing Configuration: Check the routing configuration on the NGAF and the devices on the network. Ensure that proper routes are set up to allow traffic to flow from VPN users through NGAF to the rest of the network and vice versa.

    NAT (Network Address Translation): Ensure that NAT rules on the NGAF are properly configured to translate internal IP addresses to the NGAF's external IP address as the traffic passes through. This is particularly important when traffic needs to traverse between different IP address spaces.

    Firewall Rules: Review the firewall rules on the NGAF. Make sure that there are no rules blocking the traffic from VPN users to the rest of the network. Also, ensure that appropriate rules are in place to allow VPN traffic to pass through the NGAF.

    VPN Configuration: Double-check the configuration of your VPN solution. Ensure that the VPN clients are using the correct configuration settings to connect to the NGAF and that the NGAF is properly configured to handle VPN traffic.

It seems like you're describing a network topology with an NGAF (Next-Generation Application Firewall) installed in transparent mode that is causing issues for VPN users.

In a transparent mode deployment, the NGAF might not have routing configured to properly handle VPN traffic. Ensure that the NGAF is configured to route VPN traffic correctly to and from the VPN users and the rest of the network.
