7.6 Configuring Address Mapping

Ordering your rules is important because the BIPAC-5100/5100W applies the rules in the order

Page 52 / 86

52

that you specify. When a rule matches the current packet, the BIPAC-5100/5100W takes the

corresponding action and the remaining rules are ignored. If there are any empty rules before

your new configured rule, your configured rule will be pushed up by that number of empty rules.

For example, if you have already configured rules 1 to 6 in your current set and now you

configure rule number 9. In the set summary screen, the new rule will be rule 7, not 9. Now if

you delete rule 4, rules 5 to 7 will be pushed up by 1 rule, so old rules 5, 6 and 7 become new

rules 4, 5 and 6.

To change your BIPAC-5100/5100W’s address mapping settings, click NAT, Select Full

Feature and click Edit Details to open the following screen.

The following table describes the labels in this screen.

LABEL

DESCRIPTION

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. You can only do this for

Many-to-One

and

Server

mapping types.

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.

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 SUA (i.e., PAT, port address translation), Billion's Single User

Account feature that previous Billion routers supported only.

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.

Chapter 8

Dynamic DNS Setup

802.11b is only supported for the BIPAC-5100W

This chapter discusses how to configure your BIPAC-5100/5100W to use Dynamic DNS.

8.1 Dynamic DNS

Dynamic DNS allows you to update your current dynamic IP address with one or many

dynamic DNS services so that anyone can contact you (in NetMeeting, CU-SeeMe, etc.). You

can also access your FTP server or Web site on your own computer using a DNS-like address

(for instance myhost.dhs.org, where myhost is a name of your choice) that will never change

instead of using an IP address that changes each time you reconnect. Your friends or relatives

will always be able to call you even if they don't know your IP address.

First of all, you need to have registered a dynamic DNS account with www.dyndns.org. This is

for people with a dynamic IP from their ISP or DHCP server that would still like to have a DNS

name. The Dynamic DNS service provider will give you a password or key.

8.1.1 DYNDNS Wildcard

Enabling the wildcard feature for your host causes *.yourhost.dyndns.org to be aliased to the

same IP address as yourhost.dyndns.org. This feature is useful if you want to be able to use,

for example, www.yourhost.dyndns.org and still reach your hostname.

8.2 Configuring Dynamic DNS

To change your BIPAC-5100/5100W’s DDNS, click Dynamic DNS. The screen appears as

shown.
