Blocked ports but no firewall?

[godthefather]

I'm not sure where to post this, so here it is.

I have a cingular wireless modem, and I was having trouble with the NAT in Azureus (not entirely sure how NAT works...) so I did some research and it appeared that the ports on which NAT was operating were being blocked. I have no router or firewall, either software of hardware, so I wasn't sure how this could happen. I went to www.grc.com (http://www.grc.com) and ran some of their security tests, and surprisingly, I passed every one with flying colors. My PC is completely invisible to the web. Every port that I test is in stealth mode. Yet I have done nothing to try and protet myself. according to GRC this means that my ISP (cingular) is blocking ports to prevet their customers from doing whatever, and that make sense due to the limited bandwith that a cellular signal can offer, but when I called them, a customer service rep. told me that they don't block any ports. She had me check the windows firewall (for the thousandth time) and then said it must be the software I'm using. I have no idea why or how I'm so secure, but its starting to limit what I can do, so anyone with any sugestions would be greatly appreciated.

Thanks in advance

Hello and Welcome to the Firewall Forums.

In many case the rep is not always telling the complete story but in this case I believe they are.

I just did a search for an answer for you and I found this.

Have you checked this site? They do provide a very good and detailed explanation on your exact issue. :-D

Also the FF Team will be slowly adding a Glossary for terms to help explain things like NAT etc.

I did actually go to that site, and that is where I learned about port forwarding ect... I am now wondering if perhaps the slow speed of my connection is causing things to "time out" or something. If my latency is too high then would it seem like my ports aren't here even if they are? I noticed that limewire uses port 45830 and it hasn't reported any errors. Does anyone know if it would tell me if it wasn't working?

do you have a icon in the network conection property window?

Actual problem is not LimeWire. Its your networking problem.

Hi,

I want to use this FTP server but im behind a firewall. Im using zonealarm pro at the moment. Outgoing connections is not a problem, zonealarm will grant the program permission. But for incoming connections i will need to open up some ports.

The standard port is 21 but i also hear al lot about 20 and 22? Wich should i open? Just 21? Or these other ports as well?

Thanx,
Hornox.

I think you must use pasive FTP to be able to pass through Firewall. Because active FTP opens a random data port. This can be handled using passive FTP.

Anyone know the ports that need to be opened up in the default IP Filter that comes by default with the WinIII servers? Im trying to publish some movies for a customer and im suspecting its not working becuase the ports are probably blocked by default.

Try this:
1- Set your Firewall Policy to Rules Wizard and/or Allow Most
2- Then under Advanced Settings/Firewall/Lan Settings RE Detect Network Settings

3- Then Try Your Web Browser attempts -perhaps New Rules will Pop Up

4- Then if this works, Go back to Block Most if that is/was your preference

Good Luck with your Fix

After using Anitum Outpost for about 3 months with no problems, I am finding now that with websites I have to log-in to, such as Hotmail and msn groups I have to disable Outpost.

I dont know if I have inadvertently altered something in the configuration, but it isnt an ideal situation to be in not using the firewall.

Any help would be appreciated it
