E Series firewall filter is the base WAN port. So

the source address or input destination address

should be the WAN port IP address.

FIREWALL CONFIGURATION

In_access Enable: Enables the in_access rule.

Out_access Enable: Enables the out_access rule.

Input/Output: Select rule type input rule or

output rule.

Deny/Permit: Select rule type deny rule or permit

rule.

Protocol Type: Protocol used in this rule: TCP/IP/

ICMP/UDP.

Port Range: Port range selections are more than,

less than, equal, or not equal.

Src Addr: Source address. It can be a single IP

address or a network address range.

Des Addr: Destination address. It can be an IP

address or a network address range.

Src Mask: Source address mask. Indicates the

source is dedicated IP if it is set to 255.255.255.255.

Otherwise, this is the network ID.

Des Mask: Destination address mask. Indicates

the source is dedicated IP if it is set to

255.255.255.255. Otherwise, this is the network

ID.

3.5.6 VLAN CONFIGURATION/QOS

CONFIGURATION

The E Series phones implement Virtual LANs

and Quality of Service (QoS) within this section

of the menu. The QoS is based on the 802.1p

protocol. The QoS is used to mark the network

communication priority in the data link/MAC sub-

layer. An E Series phone will sort the packets

using QoS and send it to the destination.

VLAN Enable: If enabled the traffic over the WAN

port (and the bridged LAN port) will separate

voice, signaling, and data transmission. This

is an essential security feature in hospitality

environments to separate voice on one Virtual LAN

and guest data traffic on a second Virtual LAN.

VLAN ID Check Enable: VLAN ID is the

identification of the Virtual Local Area Networks.

DiffServ Enable: If enabled the VLAN service

indicates to use the DSCP mode (DiffServ Code

Point) to differentiate three layers of QoS (Quality

of Service).

802.1P Priority: QoS (Quality of Service) is based

on the 802.1p protocol. QoS is used to tag the

packets with a Priority number (0–7 with 7 being

highest priority and 0 being lowest). Usually

voice packets will be tagged in order to ensure

that voice quality will be preserved. This tagging

happens in the Layer 2 data link/MAC sub-layer.

An E Series phone will sort the packets using QoS

and send them to the destination.

Voice VLAN ID: Is used for establishing a secure

separate Virtual LAN for Voice signaling and

traffic to the voice server. The value ranges are

0–4095. Default value is 256.
