Using a public 802.11 access point with SC

Post by Shaba1 »

I would like to use ultravncSC to do remote support. But I am often away from home using a laptop connect to the Internet true a wireless router which I do not control. Thus I cannot open a port for the vnc listener on my end. As I understand it the SC/winvnc.exe part contacts the viewer listening on port 59xxx.

Since most wireless routers act as firewalls also they would block incoming connection. Am I correct. NAT2NAT SEEMS like it would be a solution but as I understand it that does not work with SC but only with the standard Ultravnc program. As and aside I read the instructions on NAT2NAT and I understand you need a machine on the internet somewhere to server during the intial contact. That is the NatHelper. But when I look in the links for NAT2NAT I see download links for NSC.EXE and NVC.EXE but nothing for the NatHelper. Where is that program that would run on the NatHelper machine.

Thanks

The current NAT2NAT test use uvnc.com as NH server(public).

After Rel1.00 i will attack NAT2NAT again, so you can run your own server
and specify the NH in NSC and NVC. But current uvnc.com is hardcoded

Thanks Rudi. But that does not address the other part of my question. Can NAT2NAT be used with SC? The people I help are not knowledgeble enough to be able to download and install UVNC that is why SC is such a good option for me.

Yes...No

NSC connect to 5900
NVC listen to 5900

If you run NVC + SC and use port 5900 and use the NSC on the listening viewer(5900) it would work.
(Using the viewer connector on the SC and the server connector on the viewer)

But the whole setup would NOT be production ready as the user would needed to wait for green and run 2 seperate applications.

If you dare, you can also set up a repeater II (v1.02) to a computer, that is on public internet (yor office ip, DMZ, ports 5500 and 5901 forwarded). You and your customer can then connect to repeater that pass traffic to each other.

the only issue is that with repeater II there is no way to restrict connections only for you/your customers, if someone want to use also your repeater machine. In your case firewall rules don't apply as you take viewer connections from unspecific ip's

ok that was the only part of that I did not understand. Also would that not negate using SC. I like SC because the customer does ot have to understand a thing just download and click open
