Questions about ports and LANs.

Let me try to explain this the best that I can. My company that I work for installed digital camera systems with DVR capabilities. The installers set the systems up on LAN that are connected to the Internet at all times. You don't have to "dial in " to the internet, you just turn the systems on and the internet is on, no passwords needed. Each store location has a static IP addy so that the company headquarters is able to watch the stores remotely. Since the store systems are connected to the internet at all times, and they have no firewall and no virus protection, they are all infected with numerous amounts of spyware, trojans, and viruses. Alright, let me try to get to my question(s). Is there anyway to make the modem become active only when my company needs to dial in to a specific location to view the cameras? If not, is there a way to make only one port open for the company? The port that the client software uses is port 2002, it is the same for every system company wide. How can I make only that one available? What are my options? If there is any questions, I will try to answer them with the best of my computer illiterate ablities.

Thanks

wtf are they hooking unsecure hosts directly to the internet. first patch and fix those machines and install or turn on some sort of firewall. There is no reason they couldnt put those boxes on a private address and use a vpn or route the traffic appropriately. They are just asking for trouble.

What is is virtual tunnel? A technology that enables one network to send its data via another network's connections. Tunneling works by encapsulating a network protocol within packets carried by the second network. For example, Microsoft's PPTP technology enables organizations to use the Internet to transmit data across a VPN. It does this by embedding its own network protocol within the TCP/IP packets carried by the Internet.
Tunneling is also called encapsulation.


How do I set up the VPN? Short for virtual private network, a network that is constructed by using public wires to connect nodes. For example, there are a number of systems that enable you to create networks using the Internet as the medium for transporting data. These systems use encryption and other security mechanisms to ensure that only authorized users can access the network and that the data cannot be intercepted.

sounds like your company needs to hire or contract out someone who knows what they are doing if they are putting these up all over.

Your company needs to spend a few hunderd bucks and have someone come in and clean it up, or hire someone full time.
