Port Redirection etc

[OldNick]

I have just tried a couple of the Echo Server systems that are around. They simplify things but seem very slow.

I also tried running a VPN programme,and while I could connect, I could not work out how to use UVNC over it.

So I come back to direct control with UVNC, I guess.

I have read and tried to digest all the stuff about Port redirection, including the Port Forward site. Unfortunately that did not have my router. I tied looking at close models, but they looked quite different.

So I opened up my router's control and did Port Redirection.

Since UVNC uses 5900, I redirected a heap of ports to that.

In my Router (Draytek 2910) I redirected several hundred port numbers to 5900.

I also opened a heap of ports.

But then when I used GRC's tests, I found that any port I could test was in Stealth mode; none are opened according to the Net. In fact my PC did not exist!

Where to now?

Are there certain ports I should aim at? Is my ISP blocking all these ports?

I have tried it with and without firewalls, both software and router.

It would be a waste of time talking to my ISP, and I really have no choice of provider. Full stop. :-<

Any help greatly appreciated. I am lost.

Well.....31 other people also seem completely unaware of how to fix this.

Thanks folks

You should be forwarding ports to the LAN IP the machine running the server not doing whaevre confusing stuiff you seem to be doing...

To be honest I cant quite understand some of the action you taken though I undewrstand the problem.

And as to all your other comments I have to say please understand this is a free forum where people dedicate theire free time to help other for free.... so if you want private help for a fee I can help via remote.

hardware firewall could be disabled for test
software firewall coulbe be disabled for test

testing port if open or closed

connecting to UltraVNC Server
winvnc must started and listen port 5900 before start the test port for have an answer by ping or grc port probe
https://www.grc.com/x/portprobe=5900

or

UltraVNC server connecting to UltraVNC viewer ?
(reverse mode, aka call back)
vncviewer must started and listen port 5500 before start the test port for have answer by ping or grc tester
https://www.grc.com/x/portprobe=5500

I have tried opening/fprwarding ports on the router. Nada. My confusing stuff I am doing is because I am completely confused. That's why I am asking for help. I have yet to see a single place that explained step by step how to do this, unless it sends me to a dozen other places that still do not lay it out.

I spend a lot of time for free on many other forums, helping others. I hate to see some poor guy floundering around getting no answers, or those that do not help.

if port redirect not work, policy of your isp,

you can choose et set another port on winvnc
and then, never forget, vncviewer remote::40000

did you checked firmware of your firewall ? newer is not mean alway better sometime is worse.
tested another router, ?
do not confuse NAT and firewall
both need to be opened the port requested and require forward for success.
some firewall need allow outgoing and ingoing rule for success.

if redirect port fail, mean only outgoing connection allowed by your isp or any other reason.

only third solution as vnc related product can help you.
but you don't like because is slow.
What we can do except give you a magic wand ?
We are human, we don't know everything

did you try third solution below:
[topic=5612][/topic] if this solution fail, would be really strange.

I did try the "connect to office computer", but I am stuck at a certain point.

I reckon it's all blindingly simple, but something is giving me a blind spot.

I can't tell if my ISP is blocking stuff, because I am not sure if I am even getting that far.

Perhaps if I lay out my specific instance.

I have no firewalls running either H/W or S/W, for testing purposes. I will worry about _those_ later!

My router shows the following.

---Mode: (Single or range)
I chose single
---Service Name Text)
I entered "Service Name"
---Protocol : TCP or UDP
I entered two entries, one for TCP and one for UDP as you suggsesed in your link.
---Public port
????
---Private IP
Do I enter my router's address 192.168.1.1 or my PC's address on the router 192.168.1.10?
---Private port
?????

Maybe that makes it clearer where I am getting stuck.

Thanks

Sorry. I missed a point. I cannot try another router this one is the only one that allows me to connect using the MODEM I have (no choice: Wireless BB)

Here is my final setup (which does not work)
---Mode: (Single or range)
I chose single
---Service Name Text)
I entered "Service Name"
---Protocol : TCP or UDP
I entered two entries, one for TCP and one for UDP as you suggested in your link.
---Public port
5900
--- Private IP
192.168.1.1
---Private port
5900

Thanks again

I hope it's all right to join in on someone else's conversation. But I sense your frustration, and I just got it working myself. If I sound too simplistic, forgive me, I'm going to try to avoid confusion, because I think you can get it to work, too.

I'll make a couple assumptions: I'm guessing you want to control a computer that resides across the Internet behind another router, using a computer you have ready access to, perhaps your home computer. You should also have gotten the little blue UltraVNC eyeball icon to appear next to your taskbar clock on the computer you want to control, the one across the Internet. Also, the computer you want to remote control can actually browse the Internet. (If you want to control one computer in your home with another computer in your home, both connected to the same router, then things have gotten way too complicated - you need no ports open for that. See below)

I have an Ultravnc connection working between one of my boss's computers and my home computer. In fact I'm typing this thru the Ultravnc connection, just to try it out. Both are behind routers, and I was permitted to get into my Boss's router to open ports.

There were no changes necessary on my home router. All these changes had to be made on the router connected to the computer I was trying to remote contol, my boss's. You should do the same, set up the ports on the router connected to the computer you want to remote-control. This is the computer with the UltraVNC server (little blue eyeball) installed and running, not the one where you are sitting comfortably at home running the viewer.

I set up mine almost like you set up yours, with one exception:

On my boss's router, I set up the port as follows-

---Mode: (Single or range) single

---Service Name Text: Ultravnc5900 ( you can call this whatever you want, it doesn't matter)

---Protocol : (TCP or UDP) my boss's router allows both to be entered at once, so I chose BOTH. ( you may have to open two ports, one for TCP and one for UDP, but try one OR the other, perhaps TCP first, maybe your router doesn't like two different settings on the same port [I'm just guessing there])

---Public port 5900

---Private port 5900

--- Private IP 192.168.???.??? (this is the difference - you have to enter the ip address of the computer you are trying to remote-control here. 192.168.1.1 is very likely your router or your modem, and will not work. To get this address, go to control panel -> Network connections -> right-click on the 'Local Area Connection' or 'Wireless Network Connection' that is connected to your router, and choose 'Status'. On the box that pops up, choose the 'Support' tab. Copy down the 'IP Address' shown in the box. Enter this ip address in the 'Private IP' textbox on the router.)

Save everything and close off the router control window.

Now, you also need to know the Internet IP address of the computer you want to remote-control. On that computer (not the one you will be using at home), open you web browser and go to http://checkip.dyndns.org This site will show you the IP address the Internet uses to connect to the network that your remote computer is connected to. Copy down this number.

When you start your Ultravnc Viewer on your nearby computer, enter the Internet IP address, followed by two colons and the port number:

123.456.789.123::5900

(The 123.456.789.123 should be replaced with the Internet IP address given to you by checkip.dyndns.org) Don't forget TWO colons.

If you eventually get to an UltraVNC logon window asking for user name and/or password, you're in! You just need the correct user name / password, and you should get thru. I had to use the password for the user account I was logging on with, not the password I entered into the UltraVNC server setup window. Try both.

If you want to remote control a computer that is connected to the same router as the computer you want to sit in front of, then you do not need to fool around with the ports. Get the IP address from the 'Local Area Connection' or 'Wireless Network Connection' on the computer you want to remote control (see above), and enter this IP address in your UltraVNC viewer, without colons or prt numbers.

Dynamic IP addresses can break all this. I've noticed that if the power goes out, my network or Internet IP addresses may change. If your remote controlled computer's 'Local Area Connection' or 'Wireless Network Connection' IP address is dynamic, it might change, and your UltraVNC connection may not work. This one may be rather easy to make static, that is, unchanging. If the ISP for your remote-controlled computer's network gives it a dynamic Internet IP address, then the number returned by checkip.dyndns.org could change, too, sometimes without warning, and as I've seen, after every power outage. Search the forums or the Web on how to change to static IP addresses.


(BTW, after I installed the UltraVNC server on my boss's computer, I did not notice the Blue eyeball icon in the system tray next to the taskbar clock, even tho I told the installer to start the Ultravnc service. I had to go to start menu -> All programs -> UltraVNC -> UltraVNC server -or- Install Ultravnc service (I don't remember which one - see the installation help if you aren't getting the blue eyeball to appear)


Hope all this helps.

[OldNick]

Phoooh!

Ok. I will will read what you have said, and digest.

It may take a bit; there is a lot there that goes against what I have already seen.

Nick

[scottgus]

OldNick,

Hope it works. I know there's a lot to say on the web about this port stuff. What I did worked for me. It might not work for you, but we can only try. Just remember all the port numbers, router changes, IP addresses, UltraVNC server installation, etc., have to be done on the computer you want to remote-control, not the computer you're going to be sitting in front of. The only thing you should have to do on the computer you will be sitting at is run the UltraVNC Viewer, and type in the address and port of the remote computer, then the user name and/or password.

Hang in there.

(Benjamin Franklin said, "If we don't hang together, we will all hang separately.")

[OldNick]

AH. There's the rub.

(Actually I thought I had to do it on both machines)

Having to set up port redirection etc on every machine I want to remote control is exactly what I _don't_ want! I want the other end to see the whole thing as simple as possible. Each of them may have a completely different setup

What I am trying is an echo server on my own machine. But it does require that I set my own machine up right to allow server traffic.

[redge]

> and one for UDP as you suggested in your link.

any vnc won't use UDP port, don't open it for nothing.


> What I am trying is an echo server on my own machine. But it does require that I set my own machine up right to allow server traffic.

echo server must be accessible from both partners (viewer and server and must be on DMZ
echo server is not part of ultravnc and require echovncviewer part of echovnc
support of echovnc is not on ultravnc forum !
uvnc repeater is part of uvnc.

[OldNick]

I give up.

I'll leave it there. Sorry

Nick
