Key Exchange Method: Select IKE or Manual from the drop-down list 
box. Manual is useful for troubleshooting when you have problems using 
IKE key management.

Pre-Shared Key: Type your pre-shared key in this field. Enter 8 to 31 
case-sensitive ASCII characters. Both routers which would build a VPN 
tunnel must use the same pre-shared key.

Port Mapping supports multiple ports to PVC and bridging groups. Each 
group will perform as an independent network. To support this feature, 
you must create mapping groups with appropriate LAN and WAN 
interfaces using the Add button. The Remove button will remove the 
grouping and add the ungrouped interfaces to the Default group.

Figure 59   The Port Mapping Screen

To create a new mapping group:

Enter the Group name and select interfaces from the available interface 
list and add it to the grouped interface list using the arrow buttons to 
create the required mapping of the ports. The group name must be 
unique. A maximum 16 entries can be configured.

Click Apply to make the changes effective immediately.
