My Router Needs to Take a Chill Pill

[Renzeko]

Hey so when I try to torrent something, whether it be a game patch, or a demo or whatever, my router logs say that it's blocking numerous incoming and outgoing connections. Which in turn, slows down my entire network, and causes other programs on MY computer, AND other computers to time out and become disconnected from the internet.

So I've tried port forwarding, and using DMZ (Demilitarized Zone), yet my router still blocks numerous connections per second, which makes torrenting ubelievabley slow, and kills my entire network...

Anybody know anything that I could use to solve this? It's making me go nuts -.-

EDIT: Router Model: D-Link DIR-615

It could be that it detects there are unauthorized attempts at entry on ports that were indeed blocked. Remember, you must remember that once you're on a torrent network, your IP address is floating on the network and I'm not sure if this is true, but in theory, bots can take that IP address and spam you and probably DDoS attack your router.

A lot of Internet Service Providers are now "throttling" the traffic on their networks, especially the P2Ps. It could be that they have decided to also check the Torrent traffic.

D-Link ? In your router go to Advanced -> Firewall settings and disable SPI.

Is it safe? o.o

About SPI

Stateful Packet Inspection is a mechanism that is designed to keep track of all open sessions initiated from the trusted network (private LAN) destined for the un-trusted network (WAN or Internet). These connections are maintained in what is known as a state table until they timeout or are properly ended. The Firewall uses this state table as a dynamic rule-set to allow/deny incoming traffic from the WAN to reach computers on the private LAN. If the incoming traffic matches certain criteria of a currently open connection it will be allowed to pass the Firewall. If the incoming traffic does not match any criteria of any current connection in the state table or any pre-defined virtual server/port mapping it will be denied and dropped.

Think of Stateful Packet Inspection (SPI) as a request-response mechanism. For every action you perform using your PC, you are sending a “request” for that action to be carried through. Now in order for you to complete your transaction, you would need to receive a “response”.

SPI is the process where the firewall keeps track of certain attributes from all LAN initiated requests and so that when there is a return response, the firewall automatically checks to see if the attributes of the return response matches up with the initial request’s attributes. If there is a successful match, the response is allowed access into the network, otherwise, the response is denied access.

For example, when you send out an instant message to your friend, the firewall logs your outgoing message as an initial request for a chat session and waits for a response. Your friend receives your message and sends you a reply, but before that message can pop up on your screen, the firewall intercepts the message and agrees that the response data matches your initial request. The instant message goes through. If your friend were to send a message to you without you having initiated the conversation or telling the firewall to allow incoming connections, the firewall would disregard said message as there was no corresponding entry in the state table or rule set.

Jep, perfectly safe. You are not disabling your firewall. The function is helpful if you are planning on running services such as http / SSH and ftp then it adds an extra layer of security since it would help protect against things like DDOS attacks.

It's dynamic packet inspection, you should be fine. SPI filters/scans the entire datapacket instead of just the header.

It's very likely causing your issue. Of course you can also purchase a new router, most of them do not even have SPI / DPI.

Bleh, I'm pretty sure it's either my ISP (They suck anyways) or my lame router, but even with that disabled, and port forwarding, and every other type of security disabled, it still seizes my whole network and the router goes on a blocking spree.

Basically the instant I start torrenting, I can no longer ping any Steam servers, and all of my applications time out... so.. oh well Q_Q

Thanks for the help though.

You know there's a very easy way of verifying that ... remove the router, connect the PC to the modem and check it out.

Wouldn't hurt to try out.
