Security Groups

You may create security groups either via legacy Morpheus UI settings (available until end of 2026) OR via Community Hub Item deployment. Once your tenancy is onboarded into the EWC IAM, you may also create security groups via the EWC Cloud Management UI settings.

eumetcast

Create a designated security group with a descriptive name (e.g. "eumetcast" ) and add to it the following rules:

NameDirectionRule TypeProtocolPort RangeSource TypeSourceDestination TypeDestination Port Range
2268-udpingressCustom RuleTCP2268Network0.0.0.0/0Instance
8500-tcpingressCustom RuleTCP8500Network0.0.0.0/0Instance

ssh

A security group for ssh access should exist in your tenancy by default. Simply verify it is available and enforcing the following rules:
