Configuring Application Layer Gateways for DS-Lite

Last published : Sep 24, 2026
For some application layer protocols, the IP addresses and protocol port numbers are also communicated in the packet's payload. Application Layer Gateway (AGL) for a protocol parses the packet payload and does necessary changes to ensure that the protocol continues to work over DS-Lite.
The NetScaler appliance supports ALG for the following protocols for DS-Lite:
  • FTP
  • ICMP
  • TFTP
  • SIP
  • RTSP
