UltraVNC problems over WAN

I set up UltraVNC server on my machine. Now the problem is that I live in a college apartment complex with a LAN network. So accessing the router to forward ports is out of the question. Now I can access my Computer through my roomates computer, because we are in a LAN, but from a WAN i am hopeless.

One reason I see is that the IP address that I have set in my server is my machine IP address. Which only the router can see. Atleast that is what I think it means because ipconfig gives me (this is the one on my UltraVNC server) a different ip address, then what places like whatismyip.com sees.

Any suggestions?
 
if your ip address is in the following ranges you are behind a NAT device and will need static translations to access your computer from the outside.

10.x.x.x
172.16.x.x - 172.31.x.x
192.168.x.x

To make your computer accessible without port forwarding you can use a remote access proxy service on the web.
 
Unreal, thanks for the quick reply and yes my IP is in one of those ranges. So how do I go about doing the static translation or the Remote Access Proxy.
 
Well you need access to the router doing the NAT translation. Either in house or at the ISP level. Sounds like this isn't possible, as you will need a public ip/port for your machine.

There are lots of remote access proxies out there on the web. Do a search for gotomypc and you will find one there.

Basically your home pc has a connection to a server on the internet. For you to access your pc at home you simply access that proxy server on the internet (the one your pc has a connection to) and it allows you to connect by acting as the middle man.
 
alright, I went to gotomypc.com, unfortunetly you have to pay for that. So I did a search for proxy servers and came up with alist of a bunch of anonymous and unanonymous servers. Now how do I use the IP of these servers to benefit me?
 
Sorry I didnt mean to confuse by suggesting using a web browsing proxy server. I meant that the servers act as a proxy to your box internally.

You probably wont find one that is free.
 
So they only way I can use UltraVNC is basically but contacting my isp and telling them to somehow give me a static IP address? Do most ISP's charge for this.

Would port forwarding work in this situation?
 
Yes they will charge you. They may or may not allow it depending on their policies.

Most ISPs wont open the entire port range for a public IP (for obvious reasons), they will open particular destination ports for that IP.

Just let them know what ports you need opened for VNC to work.

Who knows, maybe you will get lucky and they won't charge you.
 
I think the only way it will work for you is to find a friend with a computer on the internet that he has control of.

He can run the UltraVNC Repeater on it in Mode II and then you can have you machine at the college connect to the Repeater PC in listen mode and then you can connect from anywhere on the internet to the Repeater PC address and tell it to connect to ID:xxxx.

Go to the "add-ons" section of the UltraVNC webpage and check out the info on the repeater.

Again, Mode I won't work in your case since you don't have control over the router at the college.

Take a look at the info and see what you think.
 
Alright I looked at the repeater and looks like I can make it work.......because my bros computer is connected directly to the net. So, am I even running a server on my college computer with this method? Also, If I understand my computer (college), will be connected to the internet computer all the time for me to remote access my college computer from anywhere.
 
Well I went over to a different lan and tried a NAT to NAT connection and got it to work. Now I am just hoping a Internet to NAT will work the same way. Only problem is that I have to use the very low quality setting on the viewer and every thing looks like complete A$$. Hopefully installing the video driver should fix the problem.
 
Maybe you can explain your network setup in a little more detail. You said you live in a college 'apartment' complex with a 'LAN'. Did you install some form of "cable/ DSL router" or does your uni provide you with the class c IP address (see ranges above)? If the former, you should be able to access your router and change the settings that you need to adjust. If it is the latter, you do need to run something on a computer with a public IP.
 
As for Drizzt's question. Yes I live in a college apartment with a LAN. Only thing I had to do was plug in my network cable to the RJ-45 outlet in the wall. I cannot see or access any router.

and for YeOld yes I am using their nat to nat plugin right now. It does its job but it needs a lot of work. It destroys the connection everytime. The file transfer also makes the connection crash. I am positive its the nat-to-nat causing these problems, because if I connect to my computer within my LAN, everything is smooth as silk and file transfer and all work perfectly.
