Ingress TCP 443 (HTTPS) (CIDR) WAF web service port
Ingress TCP 5001 x.x.x.x/32 (CIDR) WAF management tool(UI) pot (Only allow administrator IP)
Ingress TCP 22 (SSH) x.x.x.x/32 (CIDR) WAF SSH Terminal port (Only allow administrator IP)
Ingress TCP/HTTP 5000 IP of top LB of WAF
x.x.x.x/32 (CIDR)
health check port between WAF(redundancy) and Top LB
