Notice: This setting won’t take effect unless you save the config and reboot the
device
4.7.2 NAT Configuration
This page is for NAT configuration ,such port forward ,DMZ .
Network Address Translation (NAT) provides a mechanism for a privately
addressed network to access registered networks, such as the Internet,without
requiring a registered subnet address. This eliminates the need for host
renumbering and allows the same IP address range to be used in multiple
intranets. With NAT, the inside network continues to use its existing private or
obsolete addresses. These addresses are converted into legal addresses before
GW0220
Userguide 2.0 UK
18
packets are forwarded onto theoutside network.
Advance NAT setting. Maximum 10 items for TCP and UDP port mapping.
IPSec ALG: Enable/Disable IPSec ALG;
FTP ALG: Enable/Disable FTP ALG;
PPTP ALG: Enable/Disable PPTP ALG;
Transfer Type: Transfer type using port mapping.
Inside IP: LAN device IP for port mapping.
Inside Port: LAN device port for port mapping.
Outside Port: WAN port for port mapping.
Click Add to add new port mapping item and Delete to delete current port mapping
item.
4.7.3 NAT service configuration
4.7.3.1
Configure web browse port，the default is 80 port，if you want to enhance
system safety，you'd better change it into non-80 standard port；
Example: The ip address is 192.168.1.70 . you change the port value to 8090,
the accessing address is http://192.168.1.70:8090
But if the value is 0 ,that imply it can not be configured by web browser.
4.7.3.2
GW0220
Userguide 2.0 UK
19
Configure telnet port，the default is 23 port. You can change the value to others .
Example: The ip address is 192.168.1.70 . you change the port value to 8023,
the accessing address is telnet 192.168.1.70:8023
4.7.3.3
Enable RTP initial port configuration. It is dynamic allocation.
4.7.3.4
Configure the maximum quantity of RTP port. The default is 200；
Leased IPMAC correspondence table of DHCP.The table will display all
device getting ip address from GW0220 LAN port by DHCP .
The configuration on this page needs to be saved after modified and will go
into effect after restarting.If the Telnet, HTTP port will be modified, the port is
better to be set as greater than 1024,because the 1024 port system will save
ports.
※Set the HTTP port as 0，then the http service will be disabled.
4.7.4 Firewall
GW0220
Userguide 2.0 UK
20
Firewall setting page. User may set up firewall to prevent unauthorized Internet
users from accessing private networks connected to the Internet (input rule), or
prevent unauthorized private network devices to access the internet.
Access list support two type limits: input_access limit or output_access limit. Each
type support 10 items maximum.
GW0220 firewall filter is base WAN port. So the source address or input
destination address should be WAN port IP address.
Configuration:
in_access enable Enable in_access rule
out_access enable Enable out_access rule
Input/Output: Specify current adding rule is input rule or output rule.
Deny/Permit: Specify current adding rule is deny rule or permit rule.
Protocol Type: protocol using in this rule: TCP/IP/ICMP/UDP.
Port Range: port range if this rule
Src Addr: Source address. can be single IP address or network address.
Dest Addr: Destination address.can be IP address or network address.
Src Mask: Source address mask. Indicate the source is dedicate IP if set to
255.255.255.255. Otherwise is network ID
Des Mask: Destination address mask. Indicate the source is dedicate IP if set
to 255.255.255.255. Otherwise is network ID
Example:
Intention: Computer A can not ping computer B
Computer A connect with GW0220 LAN port
Computer A IP address is 192.168.10.2
GW0220 WAN port IP address is 192.168.0.187
GW0220
Userguide 2.0 UK
21
GW0220 LAN port IP address is 192.168.10.1
Computer B IP address is 192.168.0.200
GW0220 firewall config
4.7.5 QOS 802.1p Configuration
QoS Control based on 802.1p for different IP users. The QoS is used to mark the
network communication priority in the data link/MAC sub-layer. GW0220 will
sorted the packets using the QoS and sends it to the destination. QoS provides
service classes for accessing traffics in Internet.
DiffServ replace IP type of service . the field change to DS field . It take IP
service infomation that is necessary. It is strict three layer technology, it do not
involve the low layer tranfer technology
GW0220
Userguide 2.0 UK
22
4.7.6 SIP2 and STUN configuraton
To show the phone whether has been registered on public server or private server.
To show STUN working state
4.7.6.1 SIP STUN Configuration
STUN can support SIP terminal's penetration to NAT in the inner-net. In this way，
as long as there is conventional SIP proxy and a STUN server placed in the public
net, it will do; but STUN only supports three NAT modes：FULL CONE, restricted,
port restricted.
IF you have stun server .please input stun server address here.
The STUN server default port is 3478
The unit is minute. if you have STUN server .please input interval time for STUN`S
detection on NAT type.
GW0220
Userguide 2.0 UK
23
Configure enable/disable SIP STUN；if you have stun server .please enabe the
option.
4.7.6.2 Private server(SIP2) configuration.
Specific configuration parameter has the same meaning with public server.
Configure permit/deny private server register；；；；
Note: about how to use SIP2 ,Please refer to the Dial peer chapter.
4.7.7 Digital map configuration
4.7.7.1 Fixed digital map
End With “#”: Checked : # for the end of dialing. User dial 200300# .phone
send 200300 to server immediately . server receive 200300
Unchecked : # like digital number .Example: User dial
GW0220
Userguide 2.0 UK
24
#1966 , sever receive #1966
Fixed Length: When the length of the dialing match, the call will be sent.
Timeout: Specify the timeout of the last dial digit. The call will be sent after
timeout
End with “#” , Fixed length , Time out these three option are not repulsion
4.7.7.2 User define flexible Digital map table
Digit map is a set of rules to determine when the user has finished dialing. Digital
Map is based on some rules to judge when user end their dialing and send the
number to the server.With digital map, users don’t have to press ‘#’ key or
"call"key after dialing. If the number dialed matches some item in the digital map
table, or it doesn’t match with any item, this number will be sent out immediately.
It is not like using dial peer . Using digital map won’t change the number dialed,
the number sent is the same as the number dialed.
X Represents any one number between 0 and 9.
Tn Represents the last digit timeout. here [ n ] represents the time from 0~9
second, it is necessary. Tn must be the last two digit in the entry. If Tn is not
included in the entry, we use T0 as default, it means system will sent the
number immediately if the number matches the entry.
. (Dot) represents any number and no length limit.
[ ] Number location value range . It can be a number range(such as [1-4]), or
number is separated by comma such as [1,3,5],, or use a list such as [234]
Example:
[1-8]xxx Any 4 digits number between 1000 and 8999 sending out immediately
9xxxxxxx any 8 digits number starting with 9 sending out immediately
911 after finishing dialing 911 ,it will send out immediately
99T4 after finishing dial 911, it will send out in 4 second
9911x.T4 any more than 5 digits length starting with 9911, sending out in 4
second .
Using digital map can be combined with dial peer . First digital map will
GW0220
Userguide 2.0 UK
25
determine when the user finished dialing, then convert this number to the number
actually sent according to "dial peer table ".
When user dial 2887 or 98765432、 911 、99 、9911234，they will send out
immediately. (digital map with dial peer)
4.7.8 Call Service Configuration
Value added service configuration

Number IP table configuration
Function of number IP table is one way to implement the phone's calling online,
and the calling of the phone will be more flexible by configurating the number IP
table. For example, user know the other party's number and IP and want to make
direct call to the party by point-to-point mode： the other party's number is 1234，
make a configuration of 1234 directly ,then the phone will send the called
number1234 to the corresponding IP address； Or set numbers with prefix
matching pattern，for example, user want to make a call to a number in a certain
region（ 010），user can configure the corresponding number IP as 010T―
protocol― IP，after that, whenever user dial numbers with 010 prefix( such as 010
－62201234),the call will be made by this rule.
Bases on this configuration，we can also make the phone use different accounts
and run speed calling without manual swap. When making deletion or
modification, select the number first and click load, then click Modify and complete
the operation.
Display of calling number IP image list.
Click Add，the following figure will be shown at the lower part of the page.
GW0220
Userguide 2.0 UK
31
It is to add outgoing call number, there are two kinds of outgoing call number
setup： One is exactitude matching，after this configuration has been done, when
the number is totally the same with the user's calling number, the phone will make
the call with this number's IP address image or configuration; Another is prefix
matching（ be equivalent to PSTN's district number prefix function），if the previous
N bits of this number are the same with that of the user's calling number(the prefix
number length)，then the phone will use this number's IP address image or
configuration to make the call. When configurating the prefix matching, letter "T"
should be added behind the prefix number to be distinguished from the exactitude
matching.
Configure the calling line route： SIP and lifeline for selecting.
Configure destination address，if it is point-to-point call，then input the opposite
terminal's IP address, it can also be set as domain name and resolved the specific
IP address by DNS server of the phone. If no configuration has been made, then
the IP will be considered as 0.0.0.0. This is an optional configuration item.
Configure the other party's protocol signal port, this is optional configuration item：
when nothing is input, thenthe default of sip protocol is 5060；lifeline required no
configuration of this item, shown as 0.
GW0220
Userguide 2.0 UK
32
Configure alias，this is optional configuration item：it is the number to be used
when the other party's number has prefix；when no configuration has been made,
shown as no alias.
Configure suffix，this is optional configuration item：it is the additive dial-out
number behind the number; when no configuration has been made, shown as no
suffix；

SIP1 server receive07558309
user want to dial PSTN（010 6228）by SIP1，
while actually the called number should be
86106228，then we can configure called number
as 010T, then rep ：8610， and then set the
replacing length as 3. So that when user make a
call with 010 prefix, the number will be replaced
as 8610 plus the number and then sent out.
Relace the number that user dialed before
sending to SIP1 server.

7.2.1 Basic structure
User may use telnet command to access and manage gateway.
GW0220 adopts tree structure for telnet. Every node contains its sub-nodes or
local command. User can type “help” or “?” whenever to see sub-nodes and all
local command under current node.
Besides local command, there are some global commands can be used in each
node.
7.2.2 Basic command
GW0220
Userguide 2.0 UK
47
Logout: exit telnet mode.
Write: save current settings.
Type sub-nodes name in current node to switch to sub-node.
Type “!” or “exit” in current node to return to parent-node.
Type “help” or “?” can see all sub-nodes and all local command under current
node, every help item has comments such as <command> or <node> to
distinguish sub-nodes and local command. Type “help” or “?” in command can see
all parameters using in this command.
When typing node name or command, user no need to key the full name, use TAB
button will make it more efficient.
There are two types in command parameters: optional and required. “required”
parameter use “-” as prefix and “optional” use “_” as prefix. User may type “-” or “_”
then press TAB button for complementarily.
