Nortel Business Secure Router 252 Configuration — Basics

Type Select one of the following port mapping types.

1. One-to-One: One-to-one mode maps one private IP address to

one virtual IP address. Port numbers do not change with

one-to-one NAT mapping.

2. Many-to-One: Many-to-One mode maps multiple private IP

addresses to one virtual IP address. This is equivalent to SUA (for

example, PAT, port address translation), Business Secure Router's

Single User Account feature.

3. Many One-to-one: Many One-to-one mode maps each private

IP address to a unique virtual IP address. Port numbers do not

change with many one-to-one NAT mapping.

Private Starting IP

Address

When the Type field is configured to One-to-one, enter the (static)

IP address of the computer on your Business Secure Router's

LAN that is to use the VPN tunnel.

When the Type field is configured to Many-to-One or Many

One-to-one, enter the beginning (static) IP address of the range

of computers on your Business Secure Router's LAN that are to

use the VPN tunnel.

Private Ending IP

Address

When the Type field is configured to One-to-one, this field is N/A.

When the Type field is configured to Many-to-One or Many

One-to-one, enter the ending (static) IP address of the range of

computers on your Business Secure Router's LAN that are to use

the VPN tunnel.

Virtual Starting IP

Address

Virtual addresses must be static and correspond to the remote

IPSec router's configured remote IP addresses.

The computers on the Business Secure Router's LAN and the

remote network can function as if they were on the same subnet

when the virtual IP address(es) is on the same subnet as the

remote IP addresses.

Two active SAs can have the same virtual or remote IP address,

but not both. You can configure multiple SAs between the same

virtual and remote IP addresses, as long as only one is active at a

time.

When the Type field is configured to One-to-one or

Many-to-One, enter the (static) IP address that you want to use

for the VPN tunnel.

When the Type field is configured to Many One-to-one, enter the

beginning (static) IP address of the range of IP addresses that you

want to use for the VPN tunnel.
