<auth_algorithm> : MD5 SHA

<portlist >: 1-65535 * Archie DNS Finger FTP FTPData Gopher HTTP NFS NNTP NTP POP2 POP3 PortMap RIP SMTP SNMP SNMPTrap Syslog Telnet TFTP WAIS

The default for encrypt_algorithms is DES. The default for auth_algorithms is

MD5.

Creating an Encryption Policy

To create an encryption policy for Telnet traffic using the default encryption algorithm DesCbc from router 1 with IP address 170.0.0.1 to router 2 with IP address 180.0.0.1, follow these steps:

1On bridge/router 1, enter:

ADD !1 -IPSEC POLicy esp_pol EspXport tcp(*, Telnet) 170.0.0.1 180.0.0.1

2On bridge/router, 2 enter:

ADD !1 -IPSEC POLicy esp_pol EspXport tcp(Telnet,*) 180.0.0.1 170.0.0.1

To configure an encryption policy for Telnet traffic using the 3DES2key encryption algorithm between router 1 with IP address 170.0.0.1 and router 2 with IP address 180.0.0.1, follow these steps:

1On bridge/router 1, enter:

ADD !1 -IPSEC POLicy esp_pol EspXport tcp(Telnet,*) (*,Telnet) 170.0.0.1

180.0.0.1 3DES2key

2On bridge/router, 2 enter:

ADD !1 -IPSEC POLicy esp_pol EspXport tcp(Telnet,*) (*,Telnet) 180.0.0.1

170.0.0.1 3DES2key

Creating a Security Policy

To create a security policy to provide data confidentiality and data integrity for

PPTP tunnel traffic between router 1 and router 2, follow these steps:

1On bridge/router 1 enter:

ADD !1 -IPSEC POLicy ahesp_pol AhEspXport tcp, gre 170.0.0.1 180.0.0.1

2On bridge/router 2, enter:

ADD !1 -IPSEC POLicy ahesp_pol AhEspXport tcp, gre 180.0.0.1 170.0.0.1

Creating Key Sets To create a key set, use:

ADD -IPSEC KeySet <key_set_name> [EncryptKey (“<encrypt_key>”

“%<encrypt_key>”)] [AuthKey (“<auth_key>” “%<auth_key>”)]

The encrypt_key and auth_key must match the values on the peer system at the other end of the security association.

<key_set_name> is a name you assign to the key set you are adding.
