What ports are closed because of SP2?

by JamesL / December 16, 2004 10:40 PM PST

And how can I open them? The ports I want opened are the that deal with me downloading because I think that they're causeing my download speed to be crippled dramtically.

Yea that's my discussion from earlier if you didn't notice and I tried those options already and they still didn't work. Also can you be a little more specific about these ports are? Where at in the control panel. Opening and closing ports is new to me sorry about that.

No. I can't! Here's why.

There are some 64,000 ports and double that if we try both UDP and TCP. You surely can't expect any member to list all the blocked ports?

However, I can point you to the new Security Panel in the Control Panel and in the manage firewall options you can see what ports are allowed.

As to the other thread, I will no longer respond to this one since you have an open and ongoing thread...

Ever think about installing Zone Alarm and turning off the SP2 firewall?

Bob,

I think we where posting at the same time as I
provided a web link with all the posts listed.

Also doesn't the web only operate on common ports?
Meaning port 80 is for the WWW, another for IM and so on. Allowing communication between computers or networks without user intervention unless their is a special need.

You are welcome to use any port number for your application that you write. However, if you pick something that is in-use or is blocked your application may not flourish.

Nothing stops you in this regard.

Sort of a Darwin thing.

Leaning on you here Bob.

Networking is something I am still learning.
And I understand what you are saying about the use of
TCP/IP port numbers.

The orginal poster in both his post is thinking SP2 is his problem and unblocking more ports will increase his download speeds.

If a firewall does not block normal Internet traffic ports and poster is using these ports, increasing the number of open ports will not increase download speed only increase the systems vunerability. Increasing the MTU might but from what I have read it has dubious results. Correct?

Have also heard of bandwidth throttling by ISP for accounts that exceed max bandwidth use. Any thoughts on this?

Throttling the user.
by R. Proffitt Forum moderator / December 17, 2004 2:00 AM PST

Yes. Reports continue to note such. And P2P users rarely have the nerve to call their ISP and inquire about it.

As to the MTU and more, the ISP should note if such is required for their network, but my experience is that form 99% of us, the stock values work.

James,

Opening your ports will not change download speeds, nor do I think Sp2 has any involvement. You may have exceeded your ISPs bandwidth max use and have been flaged as a bandwith hog. No dig intended just the way it is. No Isp will admit to this throttling of bandwidth but they will do so.

Could I just add,
by MarkFlax Forum moderator / December 17, 2004 3:42 AM PST
In reply to: Web Links

that with P2P software the P2P web sites should have information on how to configure firewalls to allow the software to work.

If a particular P2P does not have it's own web site advice, (and WinMX comes to mind for me), there are plenty of helpful web sites devoted to particular P2P programs, and also dedicated forums.

Hope you don't mind me butting in.

Mark
