Host Name or IP Address of Destination Gateway The IP address of your
IPSec peer. If your connection is an IPSec Server, this field will display "Any Re-
mote Gateway".
Encapsulation Type Select between 'Tunneling' or 'Transport' encapsula-
tion. 'Transport' encapsulation is performed between two gateways (no subnets),
and therefore needs no explicit configuration. 'Tunneling' requires that you config-
ure the following parameters:
Local Subnet Define your local endpoint, by selecting one of the following
options:
IP Subnet (default) – enter Watson's Local Subnet IP Address and Local Sub-
net Mask.
IP Range – enter the 'From' and 'To' IP addresses, forming the endpoints
range of the local subnet(s).
IP Address – enter the Local IP Address to define the endpoint as a single
host.
None – select this option if you do not want to define a local endpoint. The
endpoint will be set to the gateway.
Remote Subnet This section is identical to the 'Local Subnet' section above,
but is for defining the remote endpoint.
Compress (Support IPComp) Select this check-box to compress packets dur-
ing encapsulation with the IP Payload Compression protocol. Please note that this
reduces performance (and is therefore unchecked by default).
Protect Protocol Select the protocols to protect with IPSec: All, TCP, UDP,
ICMP or GRE. When selecting TCP or UDP, additional source port and destination
port combo-boxes will appear, enabling you to select 'All' or to specify 'Single' ports
in order to define the protection of specific packets. For example, in order to protect
L2TP packets, select UDP and specify 1701 as both single source and single des-
tination ports.
Route NetBIOS Broadcasts Select this option to allow NetBIOS packets
through the IPSec tunnel, which otherwise would not meet the routing conditions
specified.
Key Exchange Method The IPSec key exchange method can be 'Automatic'
(the default) or 'Manual'. Selecting one of these options will alter the rest of the
screen.
