The ASA VPN module is enhanced with a new logical interface called Virtual Tunnel Interface (VTI), used to represent a VPN tunnel to a peer. It is also recommended to have a basic understanding ofIPsec. Because the two LAN networks have the same security levels you must allow this on ASA as following: same-security-traffic permit inter-interface, same-security-traffic permit inter-interface 1. The IKE policy and transform set are configured identically on each server. The requirement is to route LAN1 via ISP1 and LAN2 via ISP2. The VTIs subnets are 10.10.10.0/24 and 10.10.11.0/24. Not sure about whether later version supports OSPF or EIGRP. Much appreciated, this was extremely clear and easy to follow!!! The above NAT rules create dynamic NAT rules (Port Address Translation-PAT) using the corresponding outgoing interface of the ASA for traffic going from inside to ISP01 and also for inside to ISP02.

Cisco ASA: Route-Based This topic provides a route-based configuration for a Cisco ASA that is running software version 9.7.1 (or newer). Turn on 3des as an encryption type. There are numerous cases that PBR can be used. Within the Oracle Cloud Infrastructure, an IPSec VPN connection is one of the choices for connectivity between your on-premises network and your VCN. How i can solve this? The short answer is that PBR allows routing to be performed based on criteria other than destination IP address. However, Cisco ASA firewalls didnt support this until version 9.4.1 and later. Another feature to have in mind, which might prove useful, is the SLA tracking (https://www.networkstraining.com/cisco-asa-5500-dual-isp-connection/). The sample requires that ASA devices use the IKEv2 policy with access-list-based configurations, not VTI-based. This may be impractical in some cases, such as if the ISP routers are managed by the ISP or a third-party.
