8.Specify Peer IDs
Peer IDs enable the routers to identify each other when they exchange secret key information. By default, the Peer IDs are the router IP addresses. This does not work when one (or both) routers are behind a separate NAT device, because the NAT device changes the IP addresses.
Towards the bottom of the Advanced Settings page, enter a local ID (to identify this router) and a remote ID (to identify the router at the other end of the link). It does not matter what text you use as the IDs, so long as each ID is different.
Then click the OK button.
