Solve Network Connection Problems

When it comes to connecting to a network or the Internet, your connection method can change on a daily basis. If you’re well-traveled, your connection may even change on an hourly basis. Considering all the possibilities, it’s a bit surprising that problems don’t crop up more often than they do. We list some of the more common problems and a few ways to tackle them. DHCP Connections The most common wired Ethernet configuration, for home and work, is a DHCP (Dynamic Host Configuration Protocol) server that automatically assigns IP (Internet Protocol) addresses. This is perhaps the simplest connection method, as well as the least likely to cause problems. When you connect to an Ethernet network with DHCP, all of the essential properties are automatically configured for you.

Network design and defense

Computer network design can vary wildly from one corporation to the next. That said most networks follow the same design principles. By design principles I mean there is generally a demilitarized zone of DMZ where servers such as the mail, dns, and web server are found. This DMZ is kept relatively unprotected, and in turn is firewalled off from the rest of the internal network or intranet. This DMZ is there for good reason as services which companies have to offer like their web and email server are accessible via the Internet. If they are accessible then they are vulnerable to attack. We all know that there is a tremendous amount of “white noise” aka port scans, bot activity, and so on seen on the Internet at any given time.

Creating Networks with ISA 2004 (Part 2)

In part one of this article series we focused on network creation and network relationships. In this article we will focus on advanced network design and network flow within ISA 2004. We have already established in the previous article that the ISA server is used to divide networks and that networks are able to be defined and policies assigned to each network in form of a defined rule base for each network. Contrary to sensationalist belief, the DMZ and networks like it are still alive and well and have a place in networking. In fact the very people that say that the DMZ is dead are the ones that are paranoid about publishing servers that reside on the internal network and for this reason prefer to have an extremely secure back to back firewall scenario in place that offers highly secure access. This in itself is an advanced type of …
