Title: 8333 port
Post by: yodeltakid on April 21, 2011, 05:54:47 AM
In one place it says to port forward the 8333 port.  In another place it says that opening 8333 port isn't necessary.
Which should I do? 

If 8333 is open will I make bitcoins faster?

Can I port mask  outside port in router port 8333>9xxxx to port set in client 9xxxx?

Is there a way to test if the bitcoin client is setup properly, I use a variety of clients that have self test?

If you accecpt incoming connections, you can have more connections, people can caonnect to you, without opening port 8333. Maybe this picture can help you:

Use www.canyouseeme.org to check if the port is accepting incoming connections.

With a patch you could change the incoming port of the client, but it is not worth it. If you got 8333 open, the first connections may be faster.
