Release Notes for Cisco VPN 3000 Series Concentrator, Release 3.6 Through 3.6.8.B
OL-5637-02
New Features in Release 3.6.1
Dynamic DNS (DDNS Host Name Population)
Dynamic DNS passes the host name to the central site device, which uses that name in the DHCP address
request. This feature allows the DHCP server and DDNS to dynamically populate the DNS records.
L2TP/IPSec Authentication Enhancements (EAP/TLS, EAP/SDI)
Extensible Authentication Protocol (EAP) lets a VPN Concentrator proxy the authentication process to
an authentication server. This feature supports additional authentication options for the Microsoft VPN
Client (L2TP/IPSec), including CHAP (EAP/MD5), Smartcards (EAP/TLS), and RSA SecurID (SDI).
Supporting EAP pass-through on the VPN Concentrator means that Microsoft native IPSec clients can
authenticate users through Smartcards or SDI tokens.
To configure EAP, go to Configuration | User Management | Base Group or Configuration | User
Management | Groups.
Note In the PC environment, EAP and Cisco’s LEAP are not the same. If you are using Cisco LEAP, you need
a Cisco WLAN card.
MTU Interface Configuration
You can now configure the Maximum Transmission Unit (MTU) to be a value in the range from 68
through 1500 bytes. To configure the MTU, go to Configuration | Interface | Ethernet 123, General tab.
Secure Copy (SCP)
You can now do secure file transfers using the SCP (Secure CoPy) function over an SSH session. To
enable SCP, go to Configuration | System | Management Protocols | SSH and check “Enable SCP”.
LAN-to-LAN Filters on the VPN 3000 Concentrator
Release 3.6.1 lets you configure a filter to apply to the traffic that is tunneled through an IPSec
LAN-to-LAN connection. To configure LAN-to-LAN filters, go to Configuration | System| Tunneling
Protocols | IPSec LAN-to-LAN.
Management Interface Enhancements
Release 3.6.1 lets you view version and operating system information (when available) for connected
clients and connected user session information. You can also sort by any of the columns in the table. To
view these enhancements, go to the Administration | Administer Sessions screen and the Monitoring |
Sessions screen.
