Re: No-IP and Real VNC on multiple PC's
I've done this before, although only with two pc's behind the same router. For example, the router is set up to forward port 5900 to pc1, with the ip of 192.168.1.50 and port 5901 to pc 2 with the ip of 192.168.1.51. PC1 is set in vnc to listen on port 5900 and pc2 is set to listen on port 5901. You set this on the connections tab of the options for the vnc server on each pc. If I want to connect to pc1, I run the vnc client ( from work ) to the No-ip address:5900, if I want to connect to pc2, it's the No-ip address:5901. I don't know what the port range is that's allowed for the vnc server, but trial and error would seem to be a good way to find out, if the manuals don't say anything about it. You could run the client on one of your 8 pcs and connect to each of the others on different ports. - Original Message - From: Roberto Meza roberto_mez...@hotmail.com To: christop...@custommade.org.uk; vnc-list@realvnc.com Sent: Friday, September 25, 2009 9:38 AM Subject: RE: No-IP and Real VNC on multiple PC's Dear Christopher: I have only one rounter, a 2Wire 2701HG-T.

All have Real VNC software installed and the No-IP utility. Do I need multiple free No-IP accounts and multiple hosts? If the hosts are on physically separate Internet connections then yes, you'll need a no-ip hostname for each of them and you may still need to establish port mappings for each device if they're each behind a separate firewall/router. If they are on the same connection behind one NATting router/firewall, you will need to configure port forwarding for each machine and map a public port for each device. In that case, one no-ip hostname will suffice. (For example, my home network has two machines with VNC on - I might have my router configured to forward connections from port 4000 to port 5900 on machine 1, and public port 5000 to port 5900 on machine 2. Then I just connect to 'myhostname.tld:5000' in the VNC viewer connection box to establish a connection - provided port forwarding is operational on the network then it 'just works' :) ___ VNC-List mailing list VNC-List@realvnc.com To remove yourself from the list visit: http://www.realvnc.com/mailman/listinfo/vnc-list ___ VNC-List mailing list VNC-List@realvnc.com To remove yourself from the list visit: http://www.realvnc.com/mailman/listinfo/vnc-list
RE: problem with vnc server in the domain
I was thinking not necessarily with the hardware, but possibly something configured differently on your pc from the other computers. If you're working with your IT people, I'd ask them if they could run a network monitor to see what packets and protocols are reaching your machine and what's responding on it. Connection problems are most often an operating system or configuration problem from what I've seen before. Especially if other clients that are on your network are having problems connecting to your pc.

RE: How to connect to LAN from outside.
There are a few things involved here. You are dialing out from your pc trying to connect to another pc, but there are two firewalls between the two computers. 1. You have to make sure the port used by vnc is not blocked by either firewall. 2. The firewall is what has the ip address that you are connecting to. The ip address of the computer behind the firewall might not be the same as the address of the firewall. For example, I have a dsl connection. The ip address of my dsl modem is 129.234.21.50. The ip address of my computer that is behind the firewall is, however, 192.168.1.20. In order to make this work I have to have port forwarding set up on my dsl modem so that anything coming into it using the vnc port is redirected to my computer. When I run vnc from outside my network, I connect to the ip address that is owned by my dsl modem, and that port goes through it to connect to my computer. To tell whether this is your problem or not, you'd need to check the ip address on the computer and make sure whether it is the same address you are trying to connect to from the other end.

I think I got what you means. What I have to do is 1. Port forwarding the port for VNC Server in the firewall. Yes. Any packets that come in on the vnc port have to go to the computer that you really want to connect to. 2. To connect to other PC, I need to enter the DSL modem IP Address for that PC. For you information, there are 10 PC behind the firewall and Modem. What I need to do is use the IP Address for the DSL Modem like 219.94.72.177. To access to certain PC behind the Firewall and Modem, I need to add the port behind the IP Address for the DSL Modem like 219.94.72.177:56. Lets say I set the Port 5900 to the Firewall, means the Port for VNCServer for the PC should be 5956 right? So I need to dial up the IP Address 219.94.72.177:56 to access to the computer? In your case, the firewall is doing the dialing through your modem and it is getting the ip address for your network. That address is what you'd be connecting to from outside. I'm not sure if it will work to be able to connect to each pc separately that's behind your firewall. In my case I have only one pc at home that I need to connect to, so port 5900 is forwarded to only one pc. If you set the vnc server to listen on a slightly different port on each pc, for example, 5901, 5902, 5903, etc. you could try having each one of these ports forwarded to a different internal ip address, but never having done that, I can't be sure it would work. I'm doing right? The way to tell that you're doing it right is when it actually works.
