Are ISPs Intentionally Blocking Bitcoin Port 8333?
By default, Bitcoin clients connect to other bitcoin knots on TCP port 8333. If a user wants their Bitcoin client to connect to other knots, they will need to permit outgoing TCP connections on port 8333, and also will need to have the capability to accept connections on that same port.
Some Bitcoin users have reported issues attempting to connect or receive connections to their bitcoin clients across port 8333.
After spending an entire day effortlessly attempting to get a bitcoin client working from a huis rekentuig, one AT&,T Uverse customer called customer support.
After hours of phone calls and messaging AT&,T ultimately told mij the truth of what wasgoed going on, and only because I noticed it myself and demanded an response. The internet is being routed through a DVR/cable opbergruimte, and they confirmed the DVR also has a firewall.

I had to get te touch with headquarters and menace to rip it out of the wall to get a decent response.”, the disgruntled AT&,T Uverse customer concluded.
Fear not, for all hope is not lost. While some ISP may indeed be blocking port 8333, they’re not singling that specific port out. The ISP are simply blocking ports plus masse.
If users are uncertain whether their ISPs are blocking Bitcoin, they may opt to perform an inbound port test. There are several web based services that will test an inbound connection on a specific port for you. A web search of “port testing” will give users a few different free services to choose from.

A 2nd option, very similar to Bridge Mode, is to get a business account with the ISP.
