Calculate Your Maximum Sessions
Determine the maximum sessions available in a Secure Access instance.
This formula illustrates the way in which Reserved IP maps sessions to a single reserved IP.
sIP x sP x dIP x dP x nP
-
sIP (Source IP)— A single source IPv4 address. For example, use a value of
1. Secure Access supports more than one source IPv4 address at a time. The source IPv4 address is the egress IP from your organization's premises or from a roaming user device. -
sP (Source Ports)—We do not restrict source ports. Use the value of
65536for the full port range of 65,536 potential source ports. -
dIP (Destination IPs)—The total number of destination IPs, which clients can use to establish a session. To determine the greatest number of sessions supported, use the total possible number of public IPv4 addresses 3,706,452,992. To determine the fewest number of sessions supported, use 1. A value of
1emulates a fully qualified domain name (FQDN) that only supports a single IP address. All clients establish a session with the same FQDN. -
dP (Destination Ports)—We do not restrict ports. Use the value of
65536for the full port range of 65,536 destination ports. -
nP (Number of Protocols)—Secure Access only supports TCP. Use a value of
1for TCP.
