Hello Tanul,
The previous answer (from Brian kemboi) is not correct.
Configuring the AKS Standard Load Balancer with more IPs will provide you more SNAT ports. Each IP has 64000 ports.
This is documented here: https://video2.skills-academy.com/en-us/azure/aks/load-balancer-standard#configure-the-allocated-outbound-ports
"Each IP address provided by a frontend provides 64k ephemeral ports for the load balancer to use as SNAT ports."
In that documentation you can find examples on how to calculate and also on how to update the number of LB outbound IP count or update the LB with your own IP.
Hopefully this is what you are looking for! If you have additional questions, please let us know in the comments.
