How to setup UltraVNC SC for 2 support PCs on same network?

[Rudy]

We have 2 PCs which will give support to our clients.
Those PCs are on the same network.
So I want to setup UltraVNC SC with 2 supports:
support1 192.168.2.11 and support2 192.168.2.12.
What should I write in helpdesk.txt?
We don't have the static IP on the router (Belkin), but I registered domain
in no-ip.com.
What should be the LAN Port on the router and what Public Port for each PC?
How to run and setup viewer listening mode on both PCs? Can they both listen on the same port 5500?

Thanks for your help.

On your router you need to forward 2 different ports.

Router my.No-ip.com

router forward 5500 -> 192.168.2.11 5500
router forward 5501 -> 192.168.2.12 5500
You can tell to forward port 5001 to 5500 on 192.168.2.12

Set both viewers on listen on the standard 5500 port.

in helpdesk.txt
-connect my.No-ip.com:5500 -noregistry
-connect my.No-ip.com:5501 -noregistry

server-->No-ip.com:5500->192.168.2.11:5500
server-->No-ip.com:5501->192.168.2.12:5500

So on our router in virtual servers I will fill in as following?

192.168.2.11>TCP/UDP>LAN port 5500>Public port 5500>enable

and

192.168.2.12>TCP/UDP>LAN port 5500>Public port 5501>enable

And in helpdesk.txt put
-connect my.No-ip.com:5500 -noregistry
-connect my.No-ip.com:5501 -noregistry

But I don't know where to put that domain in our router and how to do
server-->No-ip.com:5500->192.168.2.11:5500
server-->No-ip.com:5501->192.168.2.12:5500

Can you please explain me more about the last: server-->etc. where to put it? Our router is Belkin F5D7632-4.

Thank you very much indeed

You don't need to.

When you have a noip.com dynalias there is a little tool that you need to
run on one of your PC. When that tool send the a network packet to
the global no-ip service, it tell the external (router) ip address.

Ping my.Noip.com ---> ping to the router.

SC server select 1-->No-ip.com:5500(router)->192.168.2.11:5500 (viewer)
SC server select 2-->No-ip.com:5501(router)->192.168.2.12:5500 (viewer)

So you said that I don't have to do anything?
Just to have No-IP DUC client running on one of the PCs that checks IP all the time and that's it?

So on router I will do port forwarding just to those 2 PCs with different public port and same LAN port and run No-IP DUC client on one PC?
Nothing else has to be done on the router right?

I didn't understand the following from you message:
Ping my.Noip.com ---> ping to the router.

SC server select 1-->No-ip.com:5500(router)->192.168.2.11:5500 (viewer)
SC server select 2-->No-ip.com:5501(router)->192.168.2.12:5500 (viewer)

What SC server are you talking about? I have got only SC listener installed and run it in listening mode.


Sorry, networking is something new for me so sometimes I don't understand some phrases.

But thank you really much for your help.

1) ping my.noip.com == ping ip_address router
You can do it in a dosbox to verify the ip adress.

2) SC server == the thing you create online and that use the helpdesk.txt

[Rudy]

Ok so just tell me. Is it what I have to do what I wrote in the previous message about that No-ip DUC client running and txt file configured as you wrote? Means on the router I don't have to put that domain anywhere just to do port forwarding for those 2 PCs.

Am I right?

Thanks.
