UVNC SC - Problem?? Router Question

[format19]

Hi,
I Have read throught the manuals etc and have followed the steps but not working for me.

I have an ADSL connection through a zyxel router with dynamic IP address and using NAT. Plugged into the router is my FreeSCO firewall with port forwarding and finally my laptop is plugged into the freeSCO box.

I have setup NO-IP account to track my ip address and is all working (if i type o1f-support.no-ip.biz into browser i get the login windo for my router)
I have created the SC exe file no problem, I have got two things setup an internal support and external support. the internal suport is just routing straight to my local LAN ip address and the external support routes to o1f-support.no-ip.biz on port 7500 (have also tried it with port 5500)

The internal support works perfectly whn i user the VNCViewer listening on port 7500.
I have set my NAT on the router to forward port 7500 to my Freesco box and have set the freesco box to forward port 7500 to my internal IP iddress.

When I start the VNCViewer listening on port 7500 and then on a customers PC (off site) also behind a zyxel router but no firewall, i fire up the sc exe file and select external support from the list it just minimizes to the task bar with a message about trying for 5 mns and then exits.

I have tried taking the freesco box out of the equation and plugging my laptop directly into the Router and setting the NAT to forward port 7500 to my laptops IP ut same thing happens.

Does the clients router have to have port 7500 forwarding to thier IP address aswell. Is there a way around this as I am dealing with customers with VERY limited knowledge of computers

Any ideas?

If you type into a web browser o1f-support.no-ip.biz:7500 should i get a login page (at the moment i just get this page can not be displayed)

ahhh!!!!

format19,


if you are not using a default port you need to use ":: instead of ":"


Stick with default ports till you get it working then modify them..

Having two firewalls is making this more complicated...

The zytel allows connections on port 7500? It then is setup to forward to the FreeSco firewall's IP? The FreeSco is setup to allow connections to port 7500? It then forwards the connection from port 7500 to an internal server? And that server is listening on 7500, or you forward to a different port?

Can you verify that any of this is working for you by checking the zytel logs and the FreeSco logs?

Are YOU able to test the connection from a remote location? Friend's house, work PC, something like that?

This is a tough one to diagnose remotely...

Hi Guys, Thanks for posting.
First Bevtech, I am not sure what you mean with ":" and "::" do you mean in the helpdesk.txt ie. o1f-support.no-ip.biz::7500
I Have tried the default port "5500" but when I couldnt get it to work some one suggested to change ports?

Anyway, I have tried to eliminate some things.
I disabled the windows firewall on my laptop

I Have used Azureus Nat Firewall tester to make sure I am getting in and out of the Nat/Firewall and it reports that Im getting through on port 7500
