Hey Nilanjan, thanks for your comment. Unfortunately there is no way to bypass it but you can use VPN, or do destination NAT on non-standard ports and divert it to actual ports. Other than that you will have to talk to your ISP to unblock the ports.
VIdeo is explained beautifully. I am learning the info from this video from a customers point of view to understand how an isp works and to select the right isp. So do you think selecting an isp that has the most number of peers ( which we can check the peering DB ) would be the best isp? I'm currently using a local isp and I feel like they are giving me speeds only to their servers and other "popular" content providers like Google. But when I try to download even the simplest of files from some random website I'm getting really poor speeds. could you make a video from a customers point of view comparing ISPs and how we as customers can choose the right one in India? Also, some ISPs do traffic shaping and throttling speeds on purpose. could you help us understand that in a better way. Thank you.
Hello Harmon, Thanks for your feedback! I don't think selecting ISP with more peers will really help. What happens in the background of the ISP is nothing straight forward, as a broadband user, the user is considered to be a low priority user the bandwidth is generally shared and speeds are always advertised as "up to" and not "guaranteed". Saying that there are so many options now in market local operators, big corporates etc that every provider is striving to give the best service possible. Your problem that you are not getting speeds from tom, dick and harry sites, the reason is that almost 70~80% traffic now is what is being provided by directly peered companies like Google, Amazon, Netflix, NCH etc etc so not many ISPs are buying much capacity of "Leased Line", or "the other traffic", that is just enough. That is why when you login to services of a company like ACT Fiber, you get awesome speeds for Google, Netflix etc and when you go to some random site it's dud. Very difficult for customer to find out about this you need to try it to know it, honestly. ISPs are not that open that they show their "available capacities" to the public, but if someone were to do that it will be game changer.
