Configuring the Cryptographic Engine Accelerator
Services Performance Engine 200 and Services Performance Engine 250 have an onboard cryptographic
engine accelerator that is shared between SSLVPN and IPSec protocols.
By default, acceleration of SSL is disabled so IPSec performance is maximized. To set up a router as an
SSLVPN gateway, enable hardware acceleration for SSLVPN with the crypto engine accelerator
bandwidth-allocation ssl fair command from global configuration mode. Issue the reload command.
Configuring SSL VPN
The Secure Socket Layer Virtual Private Network (SSL VPN) feature (also known as WebVPN) provides
support, in Cisco IOS software, for remote user access to enterprise networks from anywhere on the
Internet. Remote access is provided through a SSL–enabled SSL VPN gateway. The SSL VPN gateway
allows remote users to establish a secure VPN tunnel using a web browser. This feature provides a
