When the local IP address is a single address, type it a second time here.

When the local IP address is a range, enter the end (static) IP address, in a

range of computers on the LAN behind your NBG420N.

When the local IP address is a subnet address, enter a subnet mask on the

LAN behind your NBG420N.

Local Port Start 0 is the default and signifies any port. Type a port number from 0 to 65535.

Some of the most common IP ports are: 21, FTP; 53, DNS; 23, Telnet; 80,

HTTP; 25, SMTP; 110, POP3.

Local Port End Enter a port number in this field to define a port range. This port number must

be greater than that specified in the previous field. If Local Port Start is left at 0,

Local Port End will also remain at 0.

Remote Policy Remote IP addresses must be static and correspond to the remote IPSec

router's configured local IP addresses. The remote fields do not apply when the

Secure Gateway IP Address field is configured to 0.0.0.0. In this case only the

remote IPSec router can initiate the VPN.

Two active SAs cannot have the local and remote IP address(es) both the

same. Two active SAs can have the same local or remote IP address, but not

both. You can configure multiple SAs between the same local and remote IP

addresses, as long as only one is active at any time.

Remote Address For a single IP address, enter a (static) IP address on the network behind the

remote IPSec router.

For a specific range of IP addresses, enter the beginning (static) IP address, in

a range of computers on the network behind the remote IPSec router.

To specify IP addresses on a network by their subnet mask, enter a (static) IP

address on the network behind the remote IPSec router.

Authentication

Method

My IP Address Enter the NBG420N's static WAN IP address (if it has one) or leave the field set

to 0.0.0.0.

The NBG420N uses its current WAN IP address (static or dynamic) in setting up

the VPN tunnel if you leave this field as 0.0.0.0. If the WAN connection goes

down, the NBG420N uses the dial backup IP address for the VPN tunnel when

using dial backup or the LAN IP address when using traffic redirect.

Otherwise, you can enter one of the dynamic domain names that you have

configured (in the DDNS screen) to have the NBG420N use that dynamic

domain name's IP address.

The VPN tunnel has to be rebuilt if My IP Address changes after setup.

Local ID Type Select IP to identify this NBG420N by its IP address.

Select Domain Name to identify this NBG420N by a domain name.

Select E-mail to identify this NBG420N by an e-mail address.
