I need a solution to a LOCAL network desktop viewer. I'm currently using the built-in server ability from UltraVNC so a LAN only PC can go to http://ip:port (of a dual network card PC) and view the desktop, then use that PC to get online.

The reason being there is no internet allowed on school grounds. This is a pure backhaul solution so that all traffic is merely local to my network and nothing is public until an offsite PC with a public IP is used to browse.

Java continues to be a nail biting solution which is simply not reliable enough with mobility coming into play.

Is there a GOOD client/server viewer I can do over a simple backhaul bridge?
 
Use the built in remote desktop (RDP) client in windows. You need pro or server version of windows to enable the ability to remote into the system (Or a hack).
 
I don't have pro or server. I don't want to use an actual hack.

The end user will be hard wired with a private IP. Multiple laptops will be used but none at the same time (so they will have the same static private IP).

The laptops will be running W7 and up while the server is a simple W7 ordinary PC.
 
Wait, so you want a PC to have a net connection out, and use laptops to remote into that once PC to use a net connection, but prevent the laptops from having access out?

Create a vlan and put laptops on that vlan, then a dual nic in the main unit, one for the private network for local remote access, the other jacked into the outside. Done.

Or is this in attempt to bypass network security and break laws/rules? Then in that case the above plan will not work since you need to own physical access to that switch. Piggy backing on a private lan to an unauthorized open access point will get you in deep shit.
 
I'm not breaking any laws or rules. I run an ISP. Internet connections on school premises is not allowed because the students may want to look up (or download) sketchy stuff.

So, I have a backhaul bridge in place in which they will use a fake IP address. The laptop(s) hard wired with this fake address must type the url (fake IP address) of the *server* which has a built in remote viewer over the web that allows private IPs only to use for connections (ONE in particular that will be used at the school location).

The current viewer written is java is unsatisfactory. I'm looking for a better solution. I agree schizrade, but options are limited. I'm not too familiar with larger vlans or vpns but I'm sure they would be a large help.

Thanks,
Chris

It just seems you are going at this in an overly complicated way.

If you have a single point out, just create a wifi network with a NAT on the main box. The WAP's allow remote access to the network, and thus access to the box (using MS RDP or a remote desktop server (terminal services) for multiple simultaneous users) and once in the user simply browses the net.
 
@SRTie4k I have team viewer but I can not use the internet. Does it work via LAN only?

@schizrade I can not have internet at the location ... period.


I understand it is over complicated, but no means no. No public internet access to anyone period. Perhaps I should enforce a new policy to the school with a disclaimer. I'm not comfortable using a browser window for reliable and secure browsing.
 
RDP should work fine for this. and routes can be created to allow for this and this only to work.

Who says what I proposed would be public? Granting use of said resource would require granting access to the LAN (via wire of wifi) on a per machine basis, then credentials to access the end unit for browsing via AD/LDAP.

I guess none of us know what exactly you are trying to accomplish. "No means no", so what are you trying to get around? If there is no internet access at school, why are you trying to pipe a single hole to the net?
 
Again looking at your OP, you want to punch a hole to the outside with a single machine and restrict access to that machine running segregated from the school lan, which is fully possible with a segregated vlan, which is simple enough if you have access to the switches. Otherwise you need to create a separate physical network and ride on top of that to allow access to the machine that is running a NAT to the net.

Wait... what?
You want a single device to have access to the internet, and to be accessible by the laptops, yet you cannot have internet at the location.
How do you get a device to have an internet connection without an internet connection?

As described above.

Vlan if you have access to the switches and a box with a dual nic. You don't even need to setup a NAT.

I think he is selling internet access through a rigged up portal ("Running and ISP"). Since he has no real access to the network, I have to assume he does not have permission to do this, which makes what he is trying to do difficult without getting sniffed out. He only has 2 static IP addresses (likely assigned by the school's IT dept) and wants to setup a communication between those 2 IP addresses (changing the laptop IP's among 1 IP address) to a internet portal, but without getting caught doing so. I assume RDP (among others) is blocked on the LAN and the only solution he can find that works sucks.

Am I getting it right OP? ;)
 
schizrade:

1) I have no physical tie with the school network. They sign government contracts.
2) There is no NAT, it is a bridged network from end to end on the school's side.
3) No one is being paid anything, this is so the football team can watch recorded HD video stored on the server.
4) There is no 'rigged up portal' (see #1)
5) I am running an ISP.
6) I have more than 2 IP addresses.
7) I have exclusive network access.
8) A more efficient method is needed.
9) Sniffing can be ruled out...I'm not looking to incriminate myself on my own network by doing legal activity LOL

Q. How do you get a device to have an internet connection without an internet connection?
A: The local network sends local traffic between point A and point B. It sends a representation of a screen from one computer to another over a private IP. Only the server has 2 network cards and it resides outside of school property.

Please understand a bridged backhaul is not internet. It is a peak into a local network. If I assign a laptops NIC a private IP address it does not have internet. If I were to assign a public IP then it would have internet (this is what I have to avoid).

Sorry for the misunderstanding. Nothing illegal, fancy or fluffy. Just a local remote viewer over a lan.

wat?

for someone who's running an ISP you sure don't seem to understand the basics of routing
