I assume, for peer IP we use, is the wan interface of the Cisco ASA and not the gateway of the ISP correct? We have a block of static IPs facing the public, and have to have a router which points all the traffic to our router/gateway which points all the traffic to the ISP. We want to route the traffic to go through our ISP2.

A growing percentage of Internet traffic is protected by encryption. According to Google , approximately 95% of web browsing uses the encrypted HTTPS protocol. This trend toward traffic encryption has been driven by a few different factors. The move toward data encryption is a mixed blessing for cybersecurity.

When more of the workforce shifts to working remotely, it puts new and different strains on the infrastructure across different parts of the network, especially where VPN gateways connect to the network edge. Another strategy is to increase visibility into the traffic flowing between the network edge and VPN gateways and optimize performance.
