hi,
I want to block a range of ports with the software firewall. i have a T3200M modem. After I log in to the admin account, when I create new rules for the ipv6 firewall, i cannot enter a range of ports.
I would like to block ports from 5000 to 5500. I have tried formats like "5000:5500", "5000-5500", "5001,5002,5003.....5500". All returned error, saying invalid entries.
What is the correct way of blocking ports from 5000 to 5500 (UDP)?
Thanks in advance for your response!
