4.2.4.4 Editing an Address Mapping Rule
To edit an address mapping rule, click the rule’s link in the NAT Address
Mapping Rules screen to display the screen shown next.
Type:
1-1: One-to-one mode maps one local IP address to one global IP address. Note
that port numbers do not change for the One-to-one NAT mapping type.
M-1: Many-to-One mode maps multiple local IP addresses to one global IP
address. This is equivalent to Many to One (i.e., PAT, port address
translation). M-M Ov (Overload): Many-to-Many Overload mode maps
multiple local IP addresses to shared global IP addresses.
MM No (No Overload): Many-to-Many No Overload mode maps each local IP
address to unique global IP addresses.
Server: This type allows you to specify inside servers of different services behind
the NAT to be accessible to the outside world.
Local Start IP:
This is the starting Inside Local IP Address (ILA). Local IP
addresses are N/A for Server port mapping.
Local End IP:
This is the end Inside Local IP Address (ILA). If your rule is for all
local IP addresses, then enter 0.0.0.0 as the Local Start IP address and
255.255.255.255 as the Local End IP address. This field is N/A for One-to-one
and Server mapping types.

Global Start IP:
This is the starting Inside Global IP Address (IGA). Enter 0.0.0.0
here if you have a dynamic IP address from your ISP.
Global End IP:
This is the ending Inside Global IP Address (IGA). This field is
N/A for One-to-one, Many-to-One and Server mapping types.
Server Mapping Set:
Only available when Type is set to Server.
Select a number from 1 to 10 from the drop-down menu to choose a server set
from the NAT
- Address Mapping Rules screen.
Edit Details: Click this link to go to the NAT - Edit Port Mapping rule screen to
edit a server set that you have selected in the Server Mapping Set field.
4.2.5 Security
Inbound directions of Packet Filter rules prevent unauthorized computers or
applications accessing your local network from the Internet.
You can choose all filter rules by yourself, and the security is offer to some
sections: Telnet, FTP, TFTP, Web, SNMP, and Ping.
4.2.6 Dynamic DNS
42
Page 43 / 66
The Dynamic DNS function allows you to alias a dynamic IP address to a static
hostname, allowing users whose ISP does not assign them a static IP address to
use a domain name. This is especially useful for hosting servers via your ADSL
connection, so that anyone wishing to connect to you may use your domain
name. It rather than uses your dynamic IP address which changes from time to
time. This dynamic IP address is the WAN IP address of the router, which is
assigned to you by your ISP.
You will first need to register and establish an account with the Dynamic DNS
provider using their website, for example
Active:
Select this check box to use dynamic DNS.
Service Provider:
Select the name of your Dynamic DNS service provider.
Host Name
: Type the domain name assigned to your Planet ADE-3400/4400 by
your Dynamic DNS provider.
E-mail Address:
Type your e-mail address.
User:
Type your user name.
Password:
Type the password assigned to you.
Enable Wildcard:
Select this check box to enable DYNDNS Wildcard.
4.2.7 Time Zone
The router does not have a real time clock on board; instead, it uses the Simple
43
Page 44 / 66
Network Time Protocol (SNTP) to get the current time from an SNTP server
outside your network. Choose your local time zone. After a successful connection
to the Internet, the router will retrieve the correct local time from the SNTP server
you have specified. If you prefer to specify an SNTP server other than those in
the drop-down list, simply enter its IP address as shown above. Your ISP may
provide an SNTP server for you to use.
Time Server:
Use Time Server when Bootup:
Select the time service protocol that your time
server sends when you turn on the Router. Not all time servers support all
protocols, so you may have to check with your ISP/network administrator or use
trial and error to find a protocol that works. The main difference between them is
the format.
Daytime (RFC 867)
format is day/month/year/time zone of the server.
Time (RFC 868)
format displays a 4-byte integer giving the total number of
seconds since 1970/1/1 at 0:0:0.
The default,
NTP (RFC 1305),
is similar to Time (RFC 868).
Select
None
to enter the time and date manually.

Time Server IP Address:
Enter the IP address of your time server. Check with
your ISP/network administrator if you are unsure of this information.
Time Zone:
Choose the time zone of your location. This will set the time
difference between your time zone and Greenwich Mean Time (GMT).
Daylight Savings:
Select this option if you use daylight savings time. Daylight
saving is a period from late spring to early fall when many countries set their
clocks ahead of normal local time by one hour to give more daytime light in the
evening.
Start Date:
Enter the month and day that your daylight-savings time starts on if
you selected
Daylight Savings
.
End Date:
Enter the month and day that your daylight-savings time ends on if
you selected
Daylight Savings
.
Calibrate system clock with Time Server now:
Click this button to have your
Router use the time server (that you configured above) to set its internal system
clock. Please wait for up to 60 seconds while the ADE-3400/4400 locates the
time server. If the ADE-3400/4400 cannot find the time server, please check the
time server protocol and its IP address. If the IP address was entered correctly,
try pings it to test the connection.
Date
Current Date:
This field displays the date of your ADE-3400/4400.
Each time you reload this page, the router synchronizes the time with the time
server.
New Date (yyyy-mm-dd):
This field displays the last updated date from the time
server. When you select
None
in the
Use Time Server when Bootup
field, enter
the new date in this field and then click
Apply
.
Time
Current Time:
This field displays the time of your router. Each time you reload
this page, the ADE-3400/4400 synchronizes the time with the time server.
New Time:
This field displays the last updated time from the time server.
When you select
None
in the
Use Time Server when Bootup
field, enter the
new time in this field and then click
Apply
.
