Access the Firewall Management Center Virtual Instance on OCI

Updated: February 5, 2026

Overview

An overview of access methods for Cisco Secure Firewall Management Center Virtual on OCI. Learn how to connect using PuTTY, SSH, and OpenSSH.

You can connect to a running instance by using a Secure Shell (SSH) connection.

  • Most UNIX-style systems include an SSH client by default.

  • Windows 10 and Windows Server 2019 systems should include the OpenSSH client, which you'll need if you created your instance using the SSH keys generated by Oracle Cloud Infrastructure.

  • For other Windows versions you can download PuTTY, the free SSH client from http://www.putty.org.

Prerequisites

You'll need the following information to connect to the instance:

  • The public IP address of the instance. You can get the address from the Instance Details page in the Console. Open the navigation menu. Under Core Infrastructure, go to Compute and click Instances. Then, select your instance. Alternatively, you can use the Core Services API ListVnicAttachments and GetVnic operations.

  • The username and password of your instance.

  • The full path to the private key portion of the SSH key pair that you used when you launched the instance.

    For more information about key pairs, see Managing Key Pairs on Linux Instances.

Note

If you choose not to add a Day0 configuration, you can log in to the Firewall Management Center Virtual instance using the default credentials (admin/Admin123).

You are prompted to set the password on the first login attempt.
