Example: Create an IPsec policy profile
The following example defines a profile for AES-encryption at a key length of 128.

Creating/modifying an outgoing ACL profile for IPsec
An access control list (ACL) profile in the outgoing direction selects which outgoing traffic to encrypt and/or
authenticate, and which IPsec policy profile to use. IPsec does not require an incoming ACL.
Note
Outgoing and incoming IPsec traffic passes an ACL (if available)
twice, once before and once after encryption/authentication. So the
respective ACLs must permit the encrypted/authenticated and the
plain traffic.
For detailed information on how to set-up ACL rules, see chapter 7, “Access control list configuration” on
page 79.
Procedure: To create/modify an outgoing ACL profile for IPsec
Mode: Configure
Note
New entries are appended at the end of an ACL. Since the position in
the list is relevant, you might need to delete the ACL and rewrite it
completely.
Example: Create/modify an ACL profile for IPsec
The following example configures an outgoing ACL profile that interconnects the two private networks
192.168.1/24 and 172.16/16.
2800(cfg)#profile acl VPN_Out
2800(pf-acl)[VPN_Out]#permit ip 192.168.1.0 0.0.0.255 172.16.0.0 0.0.255.255 ipsec-
policy ToBurg
2800(pf-acl)[VPN_Out]#permit ip any any
Step Command Purpose
1 node(cfg)#profile acl name Creates or enters the ACL profile name
2 node(pf-ipstr)[name]#permit ...
[ ipsec-policy name ]
The expression ‘ipsec-policy name’ appended to a
permit ACL rule activates the IPsec policy profile
name to encrypt/authenticate the traffic identified
by this rule.
