Netopia R910 - Manual (Page 97)

Virtual Private Networks (VPN) 10-97
■ 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 Router is capable of ser ving
Telnet and HTTP, we recommend using these ser vices instead of Ping.
