Points to Consider before Configuring DS-Lite

Aug 30, 2016

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’s 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

5. The NetScaler appliance does not support the following features for DS-Lite:

  • Deterministic NAT (Note: This feature is supported in release 11.0 build 64.x and later.)
  • Static LSN maps (Note: This feature is supported in release 11.0 build 64.x and later.)
  • Hair Pin flow
  • Application layer gateways (ALG) for the following protocols:
    • Session Initiation Protocol (SIP)
    • Real Time Streaming Protocol (RTSP)
    • Point-to-Point Protocol (PPTP)
  • Subscriber aware traffic steering
