The device can be configured as a virtual server so that remote users accessing services
such as Web or FTP services via the public (WAN) IP address can be automatically
redirected to local servers in the LAN network. Depending on the requested service
(TCP/UDP port number), the device redirects the external service request to the appropriate
server within the LAN network.

IP Address Mapping

Rule Index:
Choose the rule number.
Rule Type:
One-to-one: This is the 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.
Many-to-One: This is the mode maps multiple local IP addresses to one global IP address.
This is equivalent to Many to One (i.e., PAT, port address translation).
Many-to-Many Overload: This is mode maps multiple local IP addresses to shared global IP
addresses.
Many-to-Many No Overload: This is the 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.

Public Start IP:
This is the starting Inside Public IP Address. Enter 0.0.0.0 here if you
have a dynamic IP address from your ISP.
Public End IP:
This is the ending Inside Public IP Address. This field is N/A for
One-to-one, Many-to-One
and Server mapping types.
Using port forwarding does have security implications, as outside users
will be able to connect to PCs on your network. For this reason you are
advised to use specific Virtual Server entries just for the ports your
application requires, instead of using DMZ. As doing so will result in all
connections from the WAN attempt to access to your public IP of the
DMZ PC specified
.
Attention
If you have disabled the NAT option in the WAN-ISP section, the
Virtual Server function will hence be invalid.
If the DHCP server option is enabled, you have to be very careful in
assigning the IP addresses of the virtual servers in order to avoid
conflicts. The easiest way of configuring Virtual Servers is to manually
assign static IP address to each virtual server PC, with an address that
does not fall into the range of IP addresses that are to be issued by the
DHCP server. You can configure the virtual server IP address
manually, but it must still be in the same subnet as the router.

4.3.3 ADSL
ADSL Mode:
The default setting is
Auto Sync-UP
. This mode will automatically detect
your ADSL, ADSL2+, ADSL2, G.dmt, G.lite, and T1.413. But in some area, multimode
cannot detect the ADSL line code well. If it is the case, please adjust the ADSL line code to
G.dmt or T1.413 first. If it still fails, please try the other values such as ALCTL, ADI, etc.
ADSL Type:
There are five modes “Open Annex Type and Follow DSLAM’s
Setting”, ”Annex A”, ”Annex I”, “Annex A/L”, ”Annex M” and “Annex A/I/L/M” that user can
select for this connection.

4.4 Access Management
4.4.1 ACL
Access Control Listing allows you to determine which services/protocols can access which
BIPAC 5102 Series interface from which computers.
You can configure the router for remote Telnet access or upload and download router
firmware and configuration files using FTP. To use this feature, your computer must have an
FTP client. And can use the BIPAC 5102 Series’s embedded web configurator for
configuration and file management.
ACL Rule Index:
This is item number
Secure IP Address:
The default 0.0.0.0 allows any client to use this service to remotely
manage the BIPAC 5102 Series. Type an IP address to restrict access to a client with a
matching IP address.
Application:
Choose a service that you may use to remotely manage the BIPAC 5102
Series.
Interface:
Select the access interface. Choices are
LAN
,
WAN
and
Both
.
