hmmm...
I think you misunderstood my post, however, your reply was somewhat helpful.
First, though, let me clarify. eMule is a filesharing app, like Limewire or Kazaa. Now, when I open Firefox or Internet Explorer to try to get to google.com (I've tried other sites, too), the browser tries for a while and then tells me the server could not be found. Additionally, when I open my email client (Thunderbird), which was already configured and working fine, I have the same problem - long wait, can't access server. At first I thought my internet connection had failed, but because eMule is still downloading fine, I know that's not the problem.
I just looked up a public proxy and tried accessing the internet through it. That worked fine, with the exception that I couldn't access my Gmail account (which is what my mail client is set up to access, via pop).
So, I still have filesharing capability, which is on port 4660. And now I know that I am able to use a proxy, on port 8080. No email though (port 25 maybe?).
I am hooked up to a Linksys cable/dsl router, and I don't know much about it, but it seems like it might not be allowing me to use ports I normally use. If that makes sense, any idea what else I can try? If not, how can I clarify?
Also, I said your post helped me, because I tried (on this, the working computer) an nslookup for my IP, comcast. I then pinged the resulting address on my nonworking computer and got a signal back, which hadn't worked for regular domain names like
www.google.com and
www.cnn.com. So I know that much works...
Any ideas?
