Hi guys, I've been using uTorrent for a while now and never seen a green icon down the bottom of the windows so I figure it's time for me to finally do a proper port forwarding this time. I'm using a D-Link DSL-504G router put in by Xtra, it provides internet connection for two computers.

I've checked out portforward.com before but the instruction's on the same model router is not that straight forward. Lost connection twice trying to establish a static IP (a necessary procedure if I want port forwarded for uTorrent?) and Xtra was trying to sell me a static IP (that's not what I read...)

I've done some captures of my D-Link router setup page (below), in the 3rd image under the "Port Forwarding" section I put "10.1.1.2" as my private IP, didn't touch "Protocol Type", "Private Port" left it as 0, and filled in my uTorrent port in the first blank area after "Public Port" and changed "Any Port" to "Single Port".

Saved and rebooted the router and... it didn't work.

We're with Xtra and the maximum download speed I've ever seen for uTorrent's about 90kbps (early morning, multiple good seed torrents). So questions for you guys who've done the port forwarding properly for uTorrent - what is your max speed? Much improvement?

Would be good if someone could walk me through this complicated task, say on MSN/Skype or even phone maybe? Just that I disconnected myself trying more than once and once the internet's gone the communication's lost too.

Much appreciated

The public port (WAN side) value and the private port (LAN side) value are the SAME value, i.e., both should be set to uTorrent port.

Hi there, thanks for the reply.

I tried what you suggested and then did a port test via uTorrent and the port's still not showing as properly forwarded. Could this be because I haven't set up the "Static IP"?

That seems to be the difficult part... so if someone's done it before (and they're on broadband with Xtra) I'd like to hear from you.

Cheers

Step 1: Change the router's DHCP server pool range to something like 10.1.1.50 to 10.1.1.99. Go Tools/System/Save and Reboot. Then reboot PCs and make sure that they have addresses in the new range (I haven't read the router manual)

Step 2: Configure PC with static IP address, Control Panel/Network Connections/Local area Connection Properties/TCP/IP Properties etc.

IP address 10.1.1.2
Subnet mask 255.0.0.0
Gateway 10.1.1.1 (this is the router's address)
DNS servers 202.27.158.40 and 202.27.156.72 (router's address of 10.1.1.1 should work also).

Hi Ross, Thank you for your reply again.

I've read your instruction carefully and would like to give it a go. I thought I knew about computers pretty well but these networking stuff are totally beyond me. No wonder I feel puzzled - I don't actually know what DHCP stands for hehe. (Dont worry, will look it up myself).

Now, I can follow your instruction, do I put in exactly the numbers you've given me? The only reason I haven't done it yet is because we've got more than one computer connected to the router I don't want my flatties jumping mad at me if I somehow disconnected them for the night :)

So after step 1, how do I go about making sure the PC's got the addresses in the new range? And I assume after Step 2, I reboot and my pc would have a static IP address? Then I go into the Port Forwarding section of the router again to put in my uTorrent port?

Many thanks
John

Would like to know that if I've got 3 PCs in the house sharing the same router, would it be ok just to set up static IP/port forward for one single computer or do I have to do the whole lot?

Also could you explain why DNS servers being 202.27.158.40 and 202.27.156.72 please?

Thank you so much

The DNS servers quoted are Xtra DNS servers. The router should display this information on the status page along with the current public IP address. Using the router address may also work. Use ipconfig (see below) to determine current DNS server address as assigned via DHCP to PC. The gateway address is the router's IP address (10.1.1.1 by default for this router).

I would experiment with port forwarding re: uTorrent on one PC first. If you want to forward a port to each PC then you have to use a different port on each PC/uTorrent client.

DHCP address pool obviously needs to contain at least 3 addresses if all 3 computers require DHCP leases but no harm in a range of 50 or so. Addresses outside this DHCP pool can be used as static addresses.

N.B. To determine currently assigned IP address type "ipconfig /all"  (don't type the quotes) at shell prompt.

Thanks Ross I've just successfully port forwarded for my PC. Won't worry about others at the moment.

Thank you for the DNS server values as it wasn't in the ipconfig /all window and I tried using the router address it just wouldn't work and disconnect me from the net.

Also I didn't do anything specified in your "step 1" but yeah it worked out and I've got the specific port forwarded correctly. I haven't done a reboot to the computer yet but since I'm on a static IP addy now the port should still be forwarded once rebooted?

Also, is it true that I'm more vulnerable now as I'm using this static ip as opposed to dynamic ones? What measures would you recommend if that's the case?

Cheers

Externally, static IP addresses can make you more vulnerable, but you don't have an external static IP address.
A quote from dclark - an admin at portforward.com:
The static ip address you need to setup for port forwarding, needs to be setup on your computer.  It is actually a static ip address that your router uses to send data to your computer.  Your ISP really as nothing to do with that ip address.  When your computer uses dynamic ip addressing (DHCP), it gets it's ip address from your router as well.  Changing from a dynamic to a static ip address is really only visible to computers that are on your local area network, and not from the internet.  So it brings about absolutely no change in security risk.

and

The chance of you getting hacked through your open ports is very very small.  It's not something you really even need to be worried about.  You are much more likely to download some file through Azureus that has a hidden trojan in it.

Basically the best way to protect yourself is firewalls and antivirus: XP SP2 has a built-in firewall that seems to be fairly decent and AVG makes a pretty good free anti-virus program. ZoneAlarm is a good free software firewall solution as well, if you need it. Also, make sure you have the latest versions of BitTorrent/Azureus/whatever, because with open ports, your computer is only as hackable as the program that uses the open port.

In summary: you'll be fine - just have the latest software and antivirus and firewall.

Thanks mate for getting back with all the details, it's certainly good to know setting up a static ip doesn't impose too much danger to my pc at all.

Yep I've got NOD32 running with always the latest definitions, as well as Ad-Watch, paired with Comodo (which I find comparatively easier to use than ZoneAlarm and it's free). Use Spybot and AVG as on demand scanners regularly. Used to use Spyware Doctor as well but it's become so bloated and a resource hog.

Cheers and have a nice weekend

Check out www.portforward.com - very useful site, shows you how to set up port forwarding for different applications and devices Smile
