I've installed and reinstalled limewire and it's still telling me it's detecting a firewall. I've disabled the windows firewall, configured my norton firewall to allow limewire to access the internet. I've also configured my router (2Wire 1701HG) to allow limewire access and still it's saying I'm behind a firewall. However, it will still allow me to download sometimes and other times it will freeze up. Any ideas?

What are your details?

OS(Win XP etc)
LW & Java version (help > about LW & you'll see)
Firewall you're using
Modem/router brand & model
ISP
Connection type (DSL etc)
Where you connect from (home, school etc)
Are you sharing a connection with other computers
Is this your first try with LW

Do this port test & see what result you get

Within LW, go tools > options > bug reports > view example. Scroll down to 'recieved incoming this session'. Is it true or false?

OS(Win XP etc) - Win XP
LW & Java version (help > about LW & you'll see) - LW 4.10.9 and I just downloaded the new java based on a post here
Firewall you're using - Norton
Modem/router brand & model - 2Wire 1701HG
ISP - ATT DSL
Connection type (DSL etc) - DSL
Where you connect from (home, school etc) - Home
Are you sharing a connection with other computers - No
Is this your first try with LW - Yes

Do this port test & see what result you get
http://www3.limewire.com:6346 - the test worked

Within LW, go tools > options > bug reports > view example. Scroll down to 'recieved incoming this session'. Is it true or false? - false

The strange thing is even though it's telling me that LW has detected a firewall. I'm still able to download.

Is your XP firewall disabled? If yes, then the reason for the firewall warning must be your 2wire device. Make sure it has UPnP enabled if it has that ability. Or if you're keen, manually port forward it using instructions here http://www.portforward.com/english/r...G/Limewire.htm
If you do that you won't have such problems anymore. Being not totally firewalled for LW means you'll be able to direct connect & get better results overall.

Yes my XP firewall is disabled and I also manually forwarded the port on the router. Could LW just say there is a firewall if there is not? I'm not having any issues downloading, yet anyway.

If you manually port forwarded correctly with a static ip, XP firewall is definitely off, & you configured your Norton firewall according to "these" instructions Configuring Norton Internet Security, then the problem must lay with your isp.
