Configuring Application Layer Gateways

For some Application layer protocols, the IP addresses and protocol port numbers are also communicated in the packet’s payload. Application Layer Gateway for a protocol parses the packet’s payload and does necessary changes to ensure that the protocol continues to work over LSN.

The Citrix ADC appliance supports ALG for the following protocols:

  • FTP
  • ICMP
  • TFTP
  • PPTP
  • SIP
  • RTSP
