Using SourceIp in ALB Listener Rule

vumdao profile image Vu Dao ・1 min read
  • For port 443 of an ALB, it's often set public but some domains are restricted access outside of office/working network especially those one do not have login phase (it's always possible to setup this but in this case assume no), for example, grafana.dev.com, prometheus.dev.com, datadog.dev.com, etc. Alt Text
  • To overcome this, use sourceIp in HTTPS 443 listener rule. Assume office network is 14.64.20.233/32 and 118.20.134.243/32 Alt Text
