# 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.

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

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

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.
