Enter the Remote IP Address and Remote IP Mask for the host to which you want to tunnel.

Note: A peculiarity associated with VPNs is that when a foreign agent has NAT applied to a Connection Profile 
set for ATMP data link encapsulation, the home agent and devices behind it, cannot Ping the foreign agent's 
tunnel end-point IP address. This is because ICMP packets have no por t association, and thus will be discarded 
rather than being processed by NAT.

Ordinarily, Ping is an excellent troubleshooting tool, but it will not be effective in this circumstance. Instead, use 
another TCP- or UDP-based network ser vice for troubleshooting. Since the Netopia R310 is capable of ser ving 
Telnet and HTTP, we recommend using these ser vices instead of Ping.
