Cisco VPN solutions provide exceptional security through encryption and authentication technologies that protect data in transit from unauthorized access and attacks. The Cisco ASA security appliance supports several types of VPN implementations, they are generally categorized as IPSec Based VPNs and SSL Based VPNs. The first category uses the IPSec protocol for secure communications and the second category uses SSL. SSL Based VPNs are also called WebVPN in Cisco terminology. The two general VPN categories supported by Cisco ASA are further divided into the following VPN technologies. IPSec Based VPNs: • Site-to-Site IPSec VPN: Used to connect remote LAN networks over unsecure media (e.g Internet). All traffic between sites is encrypted using IPsec protocol and integrates network features such as routing, quality of service, and multicast. Ex. It runs between ASA-to-ASA or ASA-to-Cisco Router.
In this article I will explain how to configure dual ISPs on a Cisco ASA 5505 firewall for redundancy purpose. Suppose we have a primary high-speed ISP connection, and a cheaper DSL line connected to a Secondary ISP. Normally all of our traffic should flow through the high speed primary ISP. If the primary link fails, the secondary DSL connection should be utilized for Internet access. Please note that the above scenario is valid only for Outbound traffic (i.e. from our internal network towards the Internet). The below configuration will works for ASA 5505 version 7.2(1) and above. Now i assigned a static Public IP address of 220.127.116.11 from Primary ISP and another static Public IP address of 18.104.22.168 from our Backup ISP. We will use Ethernet 0/0 for connecting to Primary ISP, Ethernet 0/1 for connecting to our Internal LAN, and Ethernet 0/2 for connecting to our Backup ISP. […]
