Ubuntu – How to open port 51413 for Transmission

transmission

Just moved to ubuntu on my macbook and spend whole day trying to open transmission port 51413.

Already done:

  1. I have ufw but i opened ports there and tried without it – probably not the problem

    51413/tcp                  ALLOW       Anywhere
    51413/tcp                  ALLOW       Anywhere (v6)
    
    21/tcp                     ALLOW OUT   Anywhere
    80                         ALLOW OUT   Anywhere
    143                        ALLOW OUT   Anywhere
    2049                       ALLOW OUT   Anywhere
    110                        ALLOW OUT   Anywhere
    135,139,445/tcp            ALLOW OUT   Anywhere
    137,138/udp                ALLOW OUT   Anywhere
    25/tcp                     ALLOW OUT   Anywhere
    631                        ALLOW OUT   Anywhere
    443/tcp                    ALLOW OUT   Anywhere
    53/udp                     ALLOW OUT   Anywhere
    123/udp                    ALLOW OUT   Anywhere
    993/tcp                    ALLOW OUT   Anywhere
    465/tcp                    ALLOW OUT   Anywhere
    51413/tcp                  ALLOW OUT   Anywhere
    
  2. router Pirelli DRG A125G; tried disabling firewall, forwarding ports according portforward.com but I have no experience with such thing so I dont know if i succeeded
    On transmission still shows port blocked and nothing is downloading…

  3. CanYouSeeMe.org tried tu use to see if ports are open but it shows that port is blocked

  4. Also tried qbitorrent it also doesnt work

Best Answer

It could very well be your ISP blocking it. Try a different port, and see if you can find any info on the web about your ISP restricting incoming traffic or BitTorrent traffic.

When troubleshooting ufw, you should just disable it temporarily to ensure it's not the problem.
