I don't know much about this stuff but I belive the router is what is acting as a firewall if not a program.

I have had a router sitting next to my computer now for about 3 or 4 months. It looks quite nifty but I havn't been able to figure it out so it just sits there :rolleyes: :D .

If you know how to use yours I would think the solution lies in how you set it up.

I am by no means an expert on these things however I also use a router (linksys as it happens) and have two computers sharing a cable connection through it.

The linksys also acts as a hardware firewall. In simple terms what it does is route requests from the individual PCs to the internet. When the replies are received it routes them to the machine which made the request. We can happily use both PCs at the same time with no ill effects. I can also happily share files both in and out simultaneously. Indeed I am doing that as we speak, while the other PC is being used for surfing and instant messaging.

As I understand it the only IP (changed every day) is the one allocated tothe router. That is the one which is visible to the WAN (Internet) If it receives unsolicited info it simply ignore it (a software firewall refuses to accept it, thus confirming that the IP is active). A hardware firewall is described as a black hole, particularly to the likes of bots searching for open systems. Basically no response is given, so the bot simply waits for the alloted time then moves on.

If you want one of the PCs to accept the unsolicited packets then you must alter the DMZ options. Any PC on your LAN can change the settings on the router, using IE. Addess will probably be http://192.168.1.1/ from there you can change various setting (indeed all of them if you are brave enough).

You should not have to change these setting from their defaults, depending on how old your router is. My DMZ PC is the router itself (i.e. ignore anything which was not requested). However I can (so far) do anything we want i.e. surfing, email, sharing, messaging, k++, eMule etc.

If you want more info about your router go to the linksys site. They have comprehensive info there. If you want more info about security etc go to the grc.com site. No links posted because of forum protocols.

My apologies I did not intend for that link to appear, however it should not send anyone anywhere. Other than users into their own router settings, where applicable. They will probably have to input a password as well, so it should be safe. Presumably anyone who knows the password has access.

Sorry

I too have a Linksys router and I have never had it stop me from sharing on Kazaa..
Now for eMule, you gotta do a little port forwarding to get it to work right, but Kazaa works just fine
