Netgear FVS336Gv2 – ProSafe Dual WAN Gigabit Firewall with SSL & IPSec VPN 참조 매뉴얼

When you create inbound and outbound firewall rules, you use firewall objects such as 
services, groups, schedules, QoS profiles, and bandwidth profiles to narrow down the firewall 
rules:

Services. A service narrows down a firewall rule to an application and a port number. For 
information about managing customized services, see 

280.

Service Groups. A service groups narrows down a firewall rule to a group of services. 
For information about managing service groups, see 

284.

IP groups. An IP group is a LAN group or a WAN group to which you add individual IP 
addresses. You can narrow down a firewall rule to such an IP group. For information 
about managing IP groups, 

Schedules. A schedule narrows down the period during which a firewall rule is applied. 
For information about managing schedules, see 

QoS profiles and priorities. A Quality of Service (QoS) profile defines the relative 
priority of an IP packet for traffic that matches a firewall rule. 

For information about creating QoS profiles for IPv4 firewall rules, see 

For information about predefined QoS priorities that are available for IPv6 firewall rules, 
see 

298.

Bandwidth profiles. A bandwidth profile allocates and limits traffic bandwidth for the 
LAN users to which an IPv4 firewall rule is applied. For information about creating 
bandwidth profiles, see 

Services are functions performed by server computers at the request of client computers. 
You can configure up to 124 custom services.
