So at the time of the second question the system should already have iptables installed.

I can’t install iptables on the 3rd question then go back to question 2nd.

Please help to solve it , thank you

Is it happening because of password missing in the question?

You need to simply SSH to devapp01 and devdb01.
Follow the below steps: -

ssh bob@devapp01

Type password - caleston123

Then install the iptables pkg: -

sudo apt install iptables

It will ask again for the password, type that password again.

Follow the above same steps for devdb01 server.

Regards,
