Security
A typical VPN IPSec Tunnel pass through is diagrammed below:
☛ NOTE:
Typically, no special configuration is necessary to use the IPSec pass through
feature.
In the diagram, VPN PC clients are shown behind the Netopia Gateway and the
secure server is at Corporate Headquarters across the WAN. You cannot have
your secure server behind the Netopia Gateway.
When multiple PCs are starting IPSec sessions, they must be started one at a
time to allow the associations to be created and mapped.
VPN IPSec Tunnel Termination
This Netopia service supports termination of VPN IPsec tunnels at the Gateway. This per-
mits tunnelling from the Gateway without the use of third-party VPN client software on your
client PCs. Currently one IPSec VPN tunnel is supported on Netopia 3300 Series Gate-
ways. Unlike VPN Passthrough, IPsec VPN tunnel is a keyed feature that you can obtained
from Netopia. See “Software Feature Keys” on page 178 and “IPSec Settings” on
page 226.
