How Can I Modify the Route Table?
A number of ways exist for modifying the route table. There are a variety of GUIs, such as the Microsoft Routing and Remote Access control, for example, but our preference is to use the basic route command from a standard command prompt. It is the standard method for accomplishing routing tasks, and it tends to remain very similar across most operating systems and platforms.
The most common modifiers are shown in Table 1.
