To remain connected, you must forward or map a port. Port forwarding or mapping is the act of making your local computer accessible to others through remote Internet access. In the case of uTorrent, port forwarding allows others (your peers) to access your uTorrent through a defined port.
VPN uses strong encryption to protect your traffic from being compromised. VPN is the safest method because it hides your true IP, thus your entire Internet connection. When you connect to a third-party VPN, you create a tunnel from your computer to the VPN server. The tunnel bypasses anything on the way, such as hackers, ISP monitors, etc. A popular VPN supporting P2P connections is OpenVPN.
how to change port of utorrent
Hi ! I changed my internet for a better speed and i have this problem with ports ,that is driving me crazy....I have to change like 20 -30 ports till i find one that works and sometime after 1 2 hours i have to search again for ports because the old one doesn't work anymore . I made the forward port in my router and in my windows 7 and still doesn't work . Any help pls? i want a port that works every time if it's possible.
Set and forward the listen port to be a "well known" port number, these are the ports that have been assigned to be used for specific services or daemons, and as such are less like to be blocked. Provided nothing on your local network is running any of these services you can use them, though be aware that your router possibly has a management interface running on port 80 (HTTP), also avoid using ports that are designated for SQL servers (1433 - 1434) and 3306 as these ports are under constant attack and you may find a DoS (Denial of Service) attack hitting your IP while the 'crackers' try to "break" the SA account password.
that list of ports is way over my knowledge ....i don't know what to pick and try on utorrent. So i think i will let it go and change 20 -30 ports till i find one that works for every torrent i download . Ty for your time .
I trust u but i don't understand why on a random port works fine (on any hour of the day) and the next day on the same port doesn't work . It's strange .....u think my isp is blocking random ports ? and this random block is on timer? why can't i find a port that works every time ?
ISPs use autonomous systems that do stateful packet inspection then record the destination port and the volume of data travelling to it, then if and when it reaches a trigger point throttling or blocking will be applied to that port.
Preferences > Connection in µTorrent. The error means another application is using the port you were attempting to use, so switching it is probably the only thing you can do. You're gonna need to forward this new port too.
Like I said, the listening error means you need to change the port to something else, as the one you're trying to use for listening for incoming connections is already in use. And yes, the OS should be selecting unused outgoing ports for you, so that shouldn't be a problem. You only need to worry about the port for incoming connections.
i changed ports in router, fw and ut. then i found in the advanced part of ut options> Web UI > connectivity. in the small box is a green check mark and an alternative listening port number entered. i used the same i use for port forwarding. i get the red button.
When you change the settings and get a yellow triangle this is a good sign. I will tell you that when I get the red circle it is because I have specified something in advanced that is not correct such as net.bind_ip for my wired NIC when it is not plugged in.
I tried using the guide DreadWingKnight gave me and I'm still getting an error. I just tried uninstalling and reinstalling and on start up it said "Target machine actively refusing connection.", there is still a red circle with an exclamation point in it in the lower right corner that when you mouse over it says "Listen Error: You should change the listen port.", and the torrents are not downloading anything. Any other ideas?
To change the incoming TCP port on uTorrent for Android: Open the uTorrent app. Tap on the Menu key > Settings . Tap on Incoming Port . Increment the port number by 1 and check if you are still experiencing connection...
2. When port forwarding is activated, the VPN app sends a request to the VPN server to open a random port that will forward traffic from the internet to the app. The active port number used for this is shown in the information panel at the top of the main app window when you connect to one of our P2P VPN servers.
Do I have to add something in the Source Net field, or just leave it blank? I've applied the settings (Apply Settings) and rebooted the router (Administration, Management, Reboot router) but I still don't get a check mark (pass) on the port test. I also tried changing the Source Net to 0.0.0.0 but to no avail.
I've also checked the Windows Firewall settings. Two exceptions were added when uTorrent was installed, one for TCP and one for UDP. I also tried adding a port exception manually. I even tried disabling the firewall but to no avail.
I'm not sure if this matters but "Enable UPnP port mapping" and "Enable NAT-PMP port mapping" settings were enabled in uTorrent. But on the DD-WRT router, the "UPnP Service" was disabled. I have now enabled it, and also removed the manual port fortwards I had added earlier. I applied the settings and rebooted the router. Now I can see "Teredo" in NAT, UPnP, Forwards. So it seems to be doing something, but I still get the yellow check mark in uTorrent when I do the port test. While typing this, another "Toredo" entry just showed up for the second computer (192.168.0.104).
I'm not sure I want UPnP enabled. Is it safe to have UPnP Service enabled? What kind of implications does that have? Does that mean the router will be dynamically accepting all connections on all ports as they come in? I still want to manually forward the port I want.
I have disabled the UPnP Service. After doing that, the entries in the "Forward" list (as seen on the screenshot above) were removed. Also, the yougetsignal.com website reports that the port is closed. At the same time, the built-in uTorrent port test reported that the port was still open. I don't trust that, it appears to be a false positive. So I rebooted the router, and now the port is reported as closed in uTorrent as well.
I currently don't have any port forwarding rules under "Port Forwarding". Where do I go from here? How do I manually set up a single port forward in DD-WRT without having to enable UPnP Service?
Now the built-in uTorrent port test says that the port is closed, but the web based port tester says it's open. I don't trust the uTorrent port test. So I'm pretty sure it's open now, not only because Yougetsignal.com says so, but because I got upload speeds of up to 500 KB/s and that's a good sign that there is outgoing traffic now.
While typing this I've also added a forwarding rule for the second computer and rebooted the router, and after starting up uTorrent on that machine (to begin port forwarding), it too now appears as closed in uTorrent but open on the web based port tester. It was showing up as closed at first, but I solved that by starting uTorrent activity. My guess is that the router was still blocking the port until I got some network activity going on.
Note how there's a small icon in the bottom right corner of uTorrent shows a green check mark. Whatever that means... This icon used to indicate that the port is open. At least that was the case in uTorrent version 1.6 or so. But now, if I click that icon I get to the port testing dialog, as usual, and if I do the port test I get a yellow check mark and a statement saying that the selected port is closed. Now what do you make of this?... at the very best it's an ambiguous and inconclusive result. If that tells us anything at all...
I don't know why it didn't work the first time. Looking back at it now, I see that have done everything correctly. Perhaps I forgot to click on the right buttons to get the changes properly registered with the router. There is sort of a "sequence" you have to go through. You first add the lines for port forwarding, then add the information, click Save once or twice, then Apply Settings, and then reboot. It's like a ritual.
You can forward the port using UPnP Service (see update 1 and 2 above). This is not really what I want, since I only need to forward a single port (OK, two ports at most). But I'll post a small step by step guide here in case someone else finds it useful.
Start uTorrent and wait a few minutes. If you have the NAT page open in the router interface you will see when the uTorrent port is successfully forwarded. You can then try running the port test in uTorrent.
Yes, they definitely are. You must be sure that the two PCs you're connecting are at those exact addresses, i.e. you didn't accidentally reverse their IPs, and they are either static IPs, or their MACs are hardcoded in the DHCP server configuration. This is to ensure they don't change.
You can test this using a program such as netcat for Windows, connecting to TCP port 31090 on 192.168.0.103 from 192.168.0.104 and then repeating in the other direction. If connection succeeds, then the PCs are configured correctly (it is possible that a firewall setting allows connecting from the intranet but not from the internet, thus rendering inter-computer testing meaningless; however, I consider this possibility as remote).
You can also use winpcap (www.winpcap.org) while you run the uTorrent check, to verify that indeed UDP and TCP packages are being sent to the PC (you'll run both uTorrent and winpcap from the same PC you're testing). If you don't see incoming packets, either there's a problem on the DD-WRT (their page says such might be fixed by hard resetting), or your ISP is filtering uTorrent traffic, or the testing site isn't functioning properly. You can verify the filtering hypothesis by having your own machine portscanned. 2ff7e9595c
