Why AWS or Azure GWLB(Gateway Loadbalancer) is not yet supported by Netscaler

main purpose of GWLB is to redirect the traffic to a WAF/IPS device for the traffic inspection using VXLAN or Geneve tunnel. The traffic is redirected via GWLB through a tunnel to a 3rd party device and once inspected by the device and is sent back again via tunnel to the GWLB and then to the original destination source.

Now looking this from Netscaler perspective, Netscaler itself is a layer7 loadbalancer and can inspect traffic. So sending traffic to Netscaler load balancer directly with inspection enabled on LB config is a better cost affective and performance adequate idea. This will avoid unnecesary packet in tunnel processing.
