<div><p>You can use Extended Sequence Number (ESN) to increase the data

transfer rate for a VPN connection.</p>
|
||
|
|
<div class="section">If you use the AH protocol or the ESP protocol and AES as the encryption
|
||
|
|
algorithm you might want to enable ESN. ESN allows you to transmit large volumes
|
||
|
|
of data at a high speed with out re-keying. The VPN connection uses a 64-bit
|
||
|
|
sequence numbers instead of 32-bit numbers over IPSec. Using 64-bit sequence
|
||
|
|
numbers allows more time before re-keying, which prevents sequence number
|
||
|
|
exhaustion and minimizes the use of system resources.<p>To enable ESN on a
|
||
|
|
VPN connection follow these steps:</p>
