So, A few days back when I was downloading a movie from torrent & it was seeding at it's best but the other day torrenting stopped and it wasn't working anymore. After researching on the internet and reviewing other people's queries. I came to realize that my ISP has blocked my ports which wasn't allowing the torrent to begin. Then, finally, I found the solution that Port Forwarding will solve this issue once in for all.
By the time, I was using PureVPN so while connected to VPN, I can't unblock the ports so the customer support told me that I would have to buy a Port Forwarding addon in my subscription then I would be able to unblock the ports and the configuration is very easy.
Thanks to Google that solution to every problem is now on my fingertips.
I am dropping a source. If any of you guys face such issue then do read it once. It will help you understand what is port forwarding and how it works.
