Points to Consider before Configuring DS-Lite

Consider the following points before configuring DS-Lite on a NetScaler appliance:

1. You must understand the different components of DS-Lite, described in RFC 6333.

2. A DS-lite configuration on a NetScaler appliance uses the LSN commands sets. In a DS-Lite configuration, the LSN client entity specifies the IPv6 address or IPv6 network address or ACL6 rules for identifying the traffic from the B4 device.  A DS-Lite configuration also includes an IPv6 profile, which specifies the IPv6 address AFTR component on a NetScaler appliance. For more information on NetScaler LSN feature, see Large Scale NAT.

3. For a DS-Lite configuration, the NetScaler appliance supports LSN for IPv4 packets that belong to one of the following protocols only. The NetScaler appliance drops IPv4 packets belonging to other protocols:

  • TCP
  • UDP
  • ICMP

4. The NetScaler appliance supports the following ALGs DS-Lite:

  • ICMP
  • FTP
  • TFTP
  • Session Initiation Protocol (SIP)
  • Real Time Streaming Protocol (RTSP)
