Netopia Netopia ISDN Router, R310

Virtual Private Networks (VPN) 10-19

■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 port 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 service for troubleshooting. Since the Netopia R310 is capable of serving

Telnet and HTTP, we recommend using these services instead of Ping.
