Quick port question?!?!?

Post by ace81748 »

got a quick question in regards to port forwarding.

The instructions state:
The following ports will need to be forwarded to the IP address of the computer running the repeater:

* 5901
* 5500

Is 5901 public and 5500 private?
Is this two separate entries?

Here is a screen shot of my port forwarding interface.

Thanks!

You'll have to enter 5901 and 5500 as seperate lines.

First enter:

ChunkVNC, 5901, 5901, 5901, 5901, TCP, repeater.ip.address
Click apply.
Do the same for port 5500.

Good luck.

Hi,
This is where I'm now, so I need some answers, please:
1-I'm running (chunkvnc) on the same PC. (Viewer, Server, Repeater),
2- I'm not behind a router, only connected to the DSL provider modem,
3-I have a static IP (No-IP),
now:
4-how can I check ports are open (5500,5901),
5-do I still have to edit \Viewer\bin\chunkviewer.ini file after compiling and put in local IP address (192.168.xxx.xxxx) instead of the WAN address,
6-Do I compile with the static (No-IP) address,
Thanks,
Jorge.

1. Obviously you won't be using the both the Viewer and Server from that PC other than testing.

2. The DSL Modem is in all likelihood ALSO a router, especially since you mention the 192.168.x.x addressing that the DSL modem/ROUTER is providing you.

3. Technically you have dynamic DNS service from No-IP.com because you have a DYNAMIC, not static IP address. But we know what you meant. :)

4. It's easy to check open ports with a service like ShieldsUp (easiest to Google it). supercoe usually recommends a different probing service. You just access the web site from the PC you think has the open ports.

5. You only have to change the INI files to use the local address (for viewer/server use within your local network) if you find your particular router doesn't relay requests for your public address back inside to the repeater for you (DNAT). Just try pinging your public IP address and see if it works. (A better test, if you can, is to try to telnet to the repeater on its public IP address and service port from another machine on the LAN.)

6. Yes, for normal use from the the outside, you'd want to compile with the No-IP provided NAME (not IP address) of your repeater/dynamic public IP address.

I assume you've configured your DSL modem/router or some local software to do the required No-IP dynamic DNS updates (as your IP address changes)?

As to port forwarding, you will in all likelihood have to get into your modem/router's interface and configure it. Look up the model number for a manual if you need to. Nothing's going to reach a private 192.168.x.x address from the outside unless you specifically port forward or DMZ.

Thanks for your reply B,
But there are some things I don't understand:
1- why I won't be using both the Viewer and Server from that PC other than testing..?
2-the dsl modem from my ISP (QWEST), doesn't have the port forwarding support, then how can I do this..?
3- with ShieldsUp, port 5500 shows :fcp-addr-srvr1(Stealth) and 5901 dont't show protocol and application, (only Stealth).
Thanks,
Jorge.

1. Because there's no reason you'd ever want to remote control or view the same machine you're sitting at. It just results in a cascading screen redraw.

2. If that's really true, you can't.

3. That's not good. But it's as expected, without port forwarding.

You haven't mentioned your DSL modem/router model, so I can't help you get into it. Usually its address is 192.168.x.1 on your local network.

One old QWest modem/router has a hack linked off http://www.dslreports.com/faq/11981

It would be surprising and sad if they were still disallowing simple things like port forwards. Good luck.

"Let me Google that for you."

First hit is QWest's own help page on this modem/router.


http://www.qwest.com/internethelp/modem ... index.html


The Advanced page has a "Port Forwarding" tutorial.

B,
I try but, with ShieldsUp, port 5500 shows :fcp-addr-srvr1(Stealth) and 5901 (Stealth) Unknown Protocol for this port (protocol and application), so maybe my ISP is blocking the ports..?
Thanks,
Jorge.

That's certainly possible. But you can pick any set of alternate ports you want, if necessary. They can't block them all. (Well, they could, but that would be a little excessive.)

More likely your port forwarding isn't configured properly. Give it another try. At the least, once you've turned on port forwarding, those ports should show as "closed" instead of stealth.

Once the remote test can actually reach the WinVNC service, the ports should come up as "open".

Also make sure you can actually reach the WinVNC machine from another machine in the LAN. You can use the loopback functionality to "view yourself" as another test.
