• Maximum concurrent TCP/UDP sessions: 75,000
• IPsec VPN throughput:
  • 56-bit DES: Up to 6 Mbps
  • 168-bit 3DES: Up to 3 Mbps
  • 128-bit AES: Up to 4.5 Mbps

Host License Tiers

Naming Rule Explanation

• PIX: Cisco legacy dedicated firewall product family acronym (Private Internet Exchange), replaced by ASA Adaptive Security Appliance line
• 501: Entry-tier model number within the PIX 500 small-office firewall sub-series
• Distinction: The PIX-501 is a fully self-contained security appliance with built-in LAN switch, unlike higher PIX models that require separate external switches for internal network termination; it is a discontinued legacy platform with no active Cisco technical support or firmware updates available.
