Required egress security group rules in OpenStack

Solution Unverified - Updated -


  • The OpenStack default security group is not allowed by our security team. We are looking for an explicit list of egress security rules required.
  • I have disabled all egress security rules and now my instance fails to boot.
  • Running instances become unresponsive after the egress rules were removed from the default security group.
  • What egress ports need to be opened in OpenStack security groups for virtual instances to run?
