ERROR: ipsec policy insertion failed because the maximum proposal limit of 20 was exceeded. The ASA OS is 9.2.3 and there is currently a site to site VPN tunnel with IKEV1 You need to upgrade first to this version which needs 2GB of RAM. If you have one of the older 5520, you need to also upgrade the memory. After upgrading, you can migrate a single VPN to IKEv2, but on the legacy ASAs SHA256 is not supported for the integrity of the IPsec SAs, only for the IKE "management-tunnels".

There are three different types supported by OPNsense which we will describe here. Mutual PSK + XAuth: You define a pre-shared key which is Two-way connectivity is is checked by receiving from the neighbor information that ws sent earlier. In general, it is called Three-way handshake, since it requires only 3 packets to verify two-way connectivity: 1) R1 sends a message (M1) with its ID (like Router-ID or Since the Cisco ASA only supports policy-based VPNs, the proxy-IDs (phase 2 selectors) must be used on the FortiGate, too. Furthermore, the ASA only supports Diffie-Hellman group 5 (and not 14), as well as SHA-1 (and not SHA-256) for IKEv1. crypto ikev2 proposal ikev2proposal encryption aes-cbc-128 integrity sha1 group 2 !

Gracias Please note that I am only showing the steps to configure the VPN (phase 1 + phase 2, i.e., IKE and IPsec/ESP), while I am NOT showing the mandatory security policies to actually allow traffic passing the firewalls. You must add appropriate security policies from the VPN zones to the internal zones (and vice versa) by yourself. Palo Alto (*) Las versiones de Cisco ASA 8.4 y posteriores incorporan compatibilidad con IKEv2, puede conectarse a la puerta de enlace de VPN de Azure mediante la directiva personalizada de IPsec/IKE con la opción "UsePolicyBasedTrafficSelectors".
