In Need of Torrent / Port Forward Help

JayR · Post by **JayR** » Mon Nov 27, 2006 8:18 pm

Fixed the DirectX problem, not I just have these questions:

"Now I have the main router in my room, and the wireless router is in the living room. Does the wireless router affect me, do I have to port forward? Is there any quick way to see if the computer has a static ip or dynamic ip?"

How many routers are you using in your hardware setup?

JayR · Post by **JayR** » Tue Nov 28, 2006 7:47 pm

There's a larger 2wire one in my living room, which is connected to one computer.
(looks similar to this: http://www.mercadolibre.com.mx/jm/img?s ... 65.jpg&v=P)

I'm using Linksys Wireless-G USB Network Adapter WUSB54G in my room, for my computer (3000+ Athlon).

Edit:
Also, I haven't been able to get a download rate higher than .02kb/s today in utorrent (it's red right now, yesterday it was blue. It says I have a port problem, as I have for weeks, when I ctrl+g).

Yesterday I downloaded about 2 gig's worth (after I used those tweak programs, my usual 10kb/s turned into 30kb/s; I even saw it jump to 100kb/s late last night).

If you connect 2 routers in a series, you have a NAT configuration.

See the following links on how to config your system for security and peer to peer connections:

The .pdf didn't work for me, so I'm installing the PS plugin now.

So, the NAT routers are one way routers? How can I configure it to open so I don't lose any packets?

I see.
Basically I need to send packets to the router in my living room using the same port at the same time...
What program would let me accomplish that? STL Port Forward? utorrent?

Honestly I have not tried running P2P from the high security zone (comp connected to the 2nd router). MY P2P is run on the less secure zone (the comp connected to the 1st router and there to the modem) since using P2P itself carries security risk.

My private and financial transactions are run from the high security zone and thus isolated in case hackers or viruses breach the comp running from the first router.

You can do the same by making your wireless router as the first router after the modem and the other comp as a high security zone and connect it to the 2nd router.

With such an arrangement, you need to just port forward on the wireless router for P2P or online games, etc.

What about the firewall in the screenshot? I've set mine as the DMZ computer...and let the one outside do a few other ports...
Or maybe a new router for my room? Would it help if it was directly connected rather than wireless?
I don't know much about routers, are they all "NAT"?

trogers · Post by **trogers** » Wed Nov 29, 2006 12:53 am

NAT routers can have the NAT function turned on or off.

It is easier to think of routing as creating layers of network.

The first layer would be the comps at the 1st router connected directly to the modem. For some homes, there is just one layer with 2 or more comps connected to the router and there to a modem.

When there is a need to create a high security network, say for parents, then the new comps will be connected to a 2nd router which then connect into the 1st router.

This would then allow the comps in the first layer to run less secure programs without worrying about breaches into the parents' comps, as they are protected by the 2nd router.

Thus comps in the first layer can port forward and poke holes through the 1st router to run their programs.

So if I just use the router in my living room and directly connect it to mine, I can port forward easily and I can download faster?

trogers · Post by **trogers** » Wed Nov 29, 2006 8:53 pm

Yes. If you connect your comp directly to the router in the living room, you need only to port forward through that one router.

Alright...sounds like it's the easiest thing I can do.

Thanks

Er, I'm back. Now I have the main router in my room, and the wireless router is in the living room. Does the wireless router affect me, do I have to port forward? Is there any quick way to see if the computer has a static ip or dynamic ip?

Oh and I'm having problems with DirectX. I try to run Counter Strike and it crashes as soon as I get in the server. I've uninstalled Steam, Counter Strike, and my graphics driver about 7 times now, and it doesn't fix the problem. I also deleted the registry key for DirectX to see if I could do a clean install, but that didn't work, so I installed a program that put back my original DirectX 8.1.

dxdiag says I have DirectX 8.1, even though I've tried just about every download of DirectX9c, including the one at Microsoft. I read somewhere that DirectX9a could work, but I couldnt find a download of it. I noticed this problem occured when I installed WindowBlinds/Object Desktop/Vista replica skin about 2 weeks ago, so I uninstalled 4 days ago.

Anyone have any ideas?

Do not touch anything of Vista unless you are using Vista on your comp. It is designed differently from XP and will be like you are installing Mac utilities on your Windows system.

DirectX9a is almost 4 years old. You will have to get it from other gamers or older game software packages.

To check your LAN IP address, go to DOS box and type ipconfig /all. If this address is constant, then it is Static. My DLink will not port forward if my comp has not set LAN IP address static.
