Functional Notes

The inbound local security parameter index (SPI) must equal the outbound remote SPI. The outbound local SPI

must equal the inbound remote SPI. The key values are the hexadecimal representations of the keys. They are

not true ASCII strings. Therefore, a key of 3031323334353637 represents “01234567”.

See the following list for key length requirements.

Algorithm: Minimum key length required:

DES 64-bits in length; 8 hexadecimal bytes

3DES 192-bits in length; 24 hexadecimal bytes

AES-128-CBC 128-bits in length; 16 hexadecimal bytes

AES-192-CBC 192-bits in length; 24 hexadecimal bytes

AES-256-CBC 256-bits in length; 32 hexadecimal bytes

MD5 128-bits in length; 16 hexadecimal bytes

SHA1 160-bits in length; 20 hexadecimal bytes

Technology Review

The following example configures an AOS product for VPN using IPSec manual keys. This example

assumes that th e AOS pr od u ct ha s been con fig ur ed with a WAN IP Address of 63.97.45.57 on interface

ppp 1 and a LAN IP Address of 10.10.10 .254 on interface ethernet 0/1. The Peer Private IP Subnet is

10.10.20.0.

For more detailed information on VPN configuration, refer to the technical support note

Configuring VPN

located on the ADTRAN OS Documentation CD provided with your unit.

Step 1:

Enter the Global Configuration mode (i.e., config terminal mode).

>enable

#configure terminal

Step 2:

Enable VPN support using the ip crypto command. This command allows crypto maps to be applied to

interfaces, and enables the IKE server to listen for IKE negotiation sessions on UDP port 500.

(config)#ip crypto

Step 3:

Define the transform set. A transform set defines the encryption and/or authentication algorithms to be

used to secure the data transmitted over the VPN tunnel. Multiple transform sets may be defined in a

system. Once a transform set is defined, ma ny different c r yp to ma p s wit hin the s y stem can ref er en ce it . In

this example, a transform set named highly_secure has been created. This transform set defines ESP

with authentication implemented using 3DES encryption and SHA1 authentication.

(config)#crypto ipsec transform-set highly_secure esp-3des esp-sha-hmac

(cfg-crypto-trans)#mode tunnel
