ID Type and content

With aggressive negotiation mode (see “Negotiation Mode” on page 239 for more

information), the Business Secure Router identifies incoming SAs by ID type and

content since this identifying information is not encrypted, so that is can

distinguish between multiple rules for SAs that connect from remote VPN

switches that have dynamic WAN IP addresses. Telecommuters can use separate

passwords to simultaneously connect to the Business Secure Router from VPN

switches with dynamic IP addresses.

With the main negotiation mode (see “Negotiation Mode” on page 239 for more

information), the ID type and content are encrypted to provide identity protection.

In this case the Business Secure Router can only distinguish between up to 12

different incoming SAs that connect from remote VPN switches that have

dynamic WAN IP addresses. The Business Secure Router can distinguish up to 12

incoming SAs because you can select between two encryption algorithms (DES

and 3DES), two authentication algorithms (MD5 and SHA1) and three key groups

(DH1, DH2, and DH5) when you configure a VPN rule (see “Configuring

advanced Branch office setup” on page 241). The ID type and content act as an

extra level of identification for incoming SAs.

Configure the ID type and content in the VPN Branch Office Rule Setup screen

(see Figure 72 on page 223). The type of ID can be a domain name, an IP address,

or an e-mail address. The content is the IP address, domain name, or e-mail

address.

Note: Regardless of the ID type and content configuration, you cannot

save multiple active rules with overlapping local and remote IP

addresses with the Business Secure Router.

Business Secure Router.
