  • Outbound access To control outbound access you can use the outbound command. You can use the PIX to construct access lists that will prevent outgoing traffic from traveling from a specific port to a specific IP, or to a specific service. The outbound command will create an access list, and the apply command applies that access list to an interface. The PIX allows all outgoing connections unless you explicitly deny them. You should deny all outbound connections and selectively permit what you want. To use the outbound command, use the following syntax: ...

  • As of November 8, 2010, Manually entered IP addresses are no longer supported on campus if the device is capable of using DHCP. This is true for normal dynamically assigned IP's and Static IP's. All NEW devices added to the network must be set to receive their network address via DHCP (Dynamic Host Configuration Protocol). This is the default setting for campus PC and Mac workstations and most printers. No user action is anticipated. There is no change or downtime expected for the vast majority of campus workstations or devices. We have made great efforts to put exceptions in place...

  • IP for 3G In this final chapter, it is appropriate to revisit the theme that started the book. Chapter 1 outlined some of the reasons why IP should be introduced into 3G networks; this chapter will explain in greater detail the technicalities of how IP could be introduced. One result will be that a network is developed that is much more faithful to the original ‘Martini’ vision than current 3G incarnations.

  • In these exercises, you will explore some basic multicast concepts via simple IP multicast applications that have been in usage for several years and are known as Mbone tools. The Mbone was the original implementation of IP multicast on the Internet. In these exercises all the hosts (your PCs) are connected to the same LAN—no multicast routing is needed at this stage.
