Ssl Vpn Specifications on Cisco ASA

Last Updated on Thu, 02 Feb 2023 | SSL Remote Access

As with any network design, you need to determine the size and scope of the SSL VPN implementation, especially the number of concurrent users that will connect to gain network access. If one Cisco ASA is not enough to support the required number of users, the available load-balancing features, such as ASA clustering, must be considered to accommodate all the potential remote users.

Table 4-1 lists the supported security appliances, their VPN throughput, and the number of supported SSL VPN users for each platform. It also specifies whether a security appliance can participate in SSL VPN load balancing.
