we are asked to open a range of ports about 200+ of them for SFTP. I can do that by modifying the /etc/ssh/sshd_config and restart the sshd services for one port, but I don't don't want to see the 200+ of the same line in the sshd_config file. Is there a way to open up a range of ports?
Please do not open such large number of ports, you are increasing system vulnerability exponentially despite we are talking about secure protocol. Are you planning to isolate different ports for different source vlans?
