Item Description
Remote Subnet Mask Subnet mask of a network behind remote side of the tunnel.
Remote Protocol/Port Specifies Protocol/Port of remote side of the tunnel. The general
form is
protocol
/
port
, for example 17/1701 for UDP (protocol 17)
and port 1701. It is also possible to enter only the number of
protocol, however, the above mentioned format is preferred.
Local ID Identifier (ID) of local side of the tunnel. It consists of two parts:
a
hostname and a domain-name .
Local Subnet IP address of a local network.
Local Subnet Mask Subnet mask of a local network.
Local Protocol/Port Specifies Protocol/Port of a local network. The general form is
protocol / port , for example 17/1701 for UDP (protocol 17) and
port 1701. It is also possible to enter only the number of protocol,
however, the above mentioned format is preferred.
Encapsulation Mode Specifies the IPsec mode, according to the method of encap-
sulation. You can select the
tunnel mode in which the entire IP
datagram is encapsulated or the transport mode in which only IP
header is encapsulated.
NAT traversal Enable/disables NAT address translation on the tunnel. If you
use NAT between the end points of the tunnel, then enable this
parameter.
IKE Mode Specifies the mode for establishing a connection ( main or ag-
gressive ). If you select the aggressive mode, then the router es-
tablishes the IPsec tunnel faster, but the encryption is perma-
nently set to 3DES-MD5.
We recommend that you not use the
aggressive mode due to lower security!
IKE Algorithm Specifies the means by which the router selects the algorithm:
•
auto – The encryption and hash algorithm are selected au-
tomatically.
•
manual – The encryption and hash algorithm are defined
by the user.
IKE Encryption Encryption algorithm – 3DES, AES128, AES192, AES256.
IKE Hash Hash algorithm – MD5, SHA1, SHA256, SHA384 or SHA512.
