The Remote Tunnel Endpoint field accepts either an IP address in the familiar dotted–quad notation a.b.c.d 
or a hostname to be resolved using the Domain Name System (DNS).
When the Remote Tunnel Endpoint is an IP address, it will drop IKE packets if they are not sourced 
from the Remote Tunnel Endpoint IP address.
When the Remote Tunnel Endpoint is a hostname, there is no check on the source address of the packet; 
hostnames are used/resolved only for initiating outgoing connections.
Multiple Network IPsec
Netopia Firmware Version 8.6.1 offers an enhancement to IPsec VPN tunnels allowing multiple network 
suppor t. This feature enhances your Netopia Router’s Vir tual Private Networking functionality.
This feature allows you to define many local and remote network ranges for a given IPsec VPN profile. Each of 
these ranges has its own IPsec tunnel. However, each tunnel has a common tunneling endpoint and encr yption 
policy. This is useful, for example, for branch office management of multiple IP subnets over an encr ypted VPN 
tunnel. The following diagram illustrates this feature:
