I just download UltraVNC. How do I connect to my home PC, from work, if my home PC is behind a reuter?

Question

My IP is assigned as 192.168.1.2

How could I connect to my PC from work? Any help?

Answer 1

You have to know the WAN address going into your home.  It probably changes once in a while so it's not something that will always be the same.  You can google "what is my ip" and find out what your WAN IP address is.

Then you need to forward ports in your router to the computer you want to connect to.  The port(s) you need to forward are explained on the VNC website, plus it has external links on how to handle configuration of port forwarding on your router.

Answer 2

Use hamachi, its a virtual private network and it works behind routers and firewalls, also any computer on it will be given a unique ip address starting with 5.x...etc ;)

Answer 3

192.168.1.2 is a private ip, which means you are behind a NAT.

Traditional way:

1. setup a dynamic DNS through http://dyndns.com, or use a software to track your home dsl ip address (usually it will change once a month).

2. setup port-forwarding on your router. Basically forward the tcp port 5900 to your pc's private ip 192.168.1.2. See http://www.portforward.com/ . Be aware that once you do that your vnc server will be exposed to the whole internet. You need to chose a strong vnc password.

3. when you access your vnc at home, you must provide the dynamic dns name or the public ip address of your home network.

Easier way:

Use Gbridge ( http://gbridge.com ). It is a free software. It has built-in ultraVNC that runs on top of a google based VPN, so it is much safer. It can penetrate NAT automatically. It is very easy to use. You only need to install gbridge on both of your machines and give each machine a name, and setup a password on the pc you want to control (click Desktopshare Icon and select "test Gbridge DesktopShare"). It would handle the rest (you would also use your google account name to help identify yourself). You do not even need to keep track your home machine's IP address! No port forwarding needed either. You just see your other machine from gbridge window and connect to it. You can even chat with your friends and send invitation to them so they can see (and control, if you allow) your desktop together with you.

Gbridge has build-in microsoft remote desktop (RDP) support. If your destination pc has RDP (xp pro or vista business/ultimate), Gbridge will help RDP to penetrate the NAT/firewall. No ip address, port forwarding hassle as well! RDP has much better performance than plain vnc.

Gbridge also provides other cool features such like folder sync, file backup, private file share among your computers or friends, which are fun to explore!
