  • Hi @NBCTCP,

    Thank you for contacting SonicWall Community.

    Based on your information, it seems like you get scrambled text when you type in the credential to login to the TZ 200 via console session. If this is right, could you ensure the firewall runs on its latest firmware version? Also, you can try to launch a normal SSH session to the LAN interface of the firewall and check for the same behavior.

    Let us know how it goes.

  • Hi @NBCTCP,

    Thanks for the answers.

    There is a good possibility that the issue is seen because of using a non-SonicWall console cable. It would be better to submit a support case with our support team to get real-time assistance on this. Our support team would be able to ship a console cable if needed to address the issue.

    Have a good one.
