Understanding Connection Types - Symantec 460R - Gateway Security Administrator's Manual

Understanding connection types

To connect the appliance to an outside or internal network, you must understand your connection type.
First, determine if you have a dial-up or broadband account. Typical dial-up accounts are analog (through a
normal phone line connected to an external modem) and ISDN (through a special phone line). Typical
dedicated accounts are broadband cable, DSL, T1/E1, or T3 connected to a terminal adaptor.
Table 3-2
Once you have determined your specific type of connection, refer to the appropriate configuration section
later in this chapter.
Note: Connect only RJ-45 cables to the WAN ports.
