  • Page 19: Client Mode With Split Tunneling

    Chapter 1 Understanding the VPN 3002 Hardware Client Client Mode and Network Extension Mode Client Mode with Split Tunneling You always assign the VPN 3002 to a tunnel group on the central-site VPN Concentrator. If you enable split tunneling for that group, IPSec and PAT are applied to all traffic that travels through the VPN 3002 to networks within the network list for that group behind the central-site VPN Concentrator.

  • Page 20: Ipsec

    Chapter 1 Understanding the VPN 3002 Hardware Client IPSec Traffic from the VPN 3002 to any destination other than those within the network list on the central-site VPN Concentrator travels in the clear without applying IPSec. NAT translates the network addresses of the devices on the VPN 3002 private network to the address of the VPN 3002 public interface.

    Chapter 1 Understanding the VPN 3002 Hardware Client Additional Software Features H.323 in PAT Mode H.323 is the packet-based multimedia communications standard written by the ITU. A variety of applications use this standard to effect real-time audio, video and data communications. It lets the VPN 3002 support Microsoft NetMeeting.
  • Page 26 A PC can register with either a GateKeeper or with an ILS server, but not both simultaneously. Note Gateway A Cisco IOS H.323 Gateway, for example, a Cisco 3620 router. Gateways let H.323 devices, in this case NetMeeting PCs, communicate with non-H.323 devices, such as POTS phones.

  • Page 27: Notes On H.323 Gatekeepers

    Log off from the GateKeeper before disconnecting the tunnel. Set the GateKeeper registration timeout value to a shorter time period. We recommend 15 minutes. Use the ‘endpoint ttl’ command on the Cisco GateKeeper to set this value. RADIUS with Password Expiry RADIUS with password expiry is an IPSec authentication method that you configure for a VPN 3002 on on the VPN Concentrator to which it connects.
