If the MCP run-time key for IPsec is present, IPsec can be initialized. Because IPsec was previously only supported on IPv6 networks, the IPv6 product key is also required for IPsec, even if the configuration only uses IPv4. IPsec can be initialized by enabling the IPsec option of the TCPIP OPT command as follows:

NW TCPIP OPT + IPSEC

During IPsec initialization, TCP/IP calls Security Center to retrieve IPsec policies. Security Center creates and manages the policies and saves them in the Security Center database. When IPsec is enabled, these policies are activated in TCP/IP. IPsec uses these policies to secure IP network data. For further information on Security Center and IPsec, refer to the MCP Security Overview and Implementation Guide.
