300-730 SVPN: Implementing Secure Solutions with Virtual Private Networks

An ISAKMP MM_NO_STATE result means that an IKE/ISAKMP Phase 1 security association has not been established. The peers must have matching Phase 1 policy parameters, such as authentication method, encryption, hash, Diffie-Hellman group, and lifetime, for the negotiation to proceed.

The Clientless SSL VPN portal provides built-in access to HTTP/HTTPS web resources and CIFS file shares. ICA, VNC, and RDP depend on separately configured client-server plug-ins rather than being enabled by default.

Advanced Endpoint Assessment enhances Host Scan with remediation actions that can attempt to update noncompliant computers to meet required version requirements, enabling the endpoint to satisfy the enterprise security policy.

Route-based IPsec virtual tunnel interfaces create an automatically generated Tunnel<number>-head-0 crypto-map entry and commonly use any-to-any IPsec traffic selectors. FlexVPN is built on this tunnel-interface/VTI model, so both FlexVPN and VTI can produce this form of IPsec SA output. GRE and DMVPN tunnel protection instead identifies GRE traffic with IP protocol 47, whereas a conventional crypto map is typically associated with a physical interface and ACL-selected traffic.

A FlexVPN server supports an IPv6 dVTI session when its IKEv2 profile is associated with a virtual template and the virtual template is configured for tunnel mode ipsec ipv6. The IPv6 address pool, DNS servers, and subnet ACL are supplied through the IKEv2 authorization policy; authentication is certificate-based RSA signatures with local AAA group authorization.
