Which computers can communicate to each other?
Network technologies allow two or more computers to connect with each other. The most common of these technologies include Local Area Network (LAN), Wireless Area Network (WAN), the Internet via client servers and Bluetooth.
What type of address allows one computer or device to communicate with another one across two or more different networks?
An IP address, or Internet Protocol address, is a series of numbers that identifies any device on a network. Computers use IP addresses to communicate with each other both over the internet as well as on other networks.
How do I connect two computers on a private network?
If you have two PCs that you want to network but no router, you can connect them using an Ethernet crossover cable or establish an ad-hoc wireless network if they have Wi-Fi hardware. You can do anything you could on a normal network after hooking them up, including sharing files and printers.
How can two computers in different network communicate?
Under normal, non-hacker circumstances, the NAT routers at each end would need to have port forwarding enabled for each PC’s private address, or the routers would need to be using one-to-one NAT, to enable the two PCs to communicate via the public addresses. You could also use a VPN between the two PCs to get around the NAT problem.
Can you use two hardware firewalls on one network?
But, I heard you can use two firewalls if the first one is a software firewall and the second is a hardware firewall, so by that clearly we can use a hardware and a software firewall together. But can you use two hardware firewalls on one network?
Which is behind the first firewall and which is the second?
Behind the first is the DMZ with “honey pot” which monitors traffic, has the Email Proxy, Browser Proxy, and the Internet servers; all SE Linux. Honey Pot information helps in creating the Black List for the second firewall. Behind the second firewall is the Intranet servers, printers, and low security (Windows) computers.
What are the advantages and disadvantages of two firewalls?
There are both advantages and disadvantages having two firewalls. While firewalls are not commonly exploited, they are prone to denial of service attacks. In a topology with a single firewall serving both internal and external users (LAN and WAN), it acts as a shared resource for these two zones.
