Use this IP mask for the remote LAN subnet. The mask sets the range of IP addresses
that will be allowed to use the IPsec tunnel.
Remote Subnet ID
Normally used with L2TP/IPsec VPNs. When the router is in server mode and negotiating
IPsec from behind a NAT box, this parameter should be configured to the ID sent by the
remote Windows client (this is usually the computer name).
Use the following security on this tunnel
These define the security identities used on the IPsec tunnel.
Preshared Keys
Requires that both IPsec peers share a secret key, or
password, that can be matched by and verified by both
peers.
To configure the PSK, a user will need configuring that
matches the inbound ID of the remote peer and the PSK
is configured using the password parameter. This is done
via Configuration – Security > Users. The User
configuration serves a dual purpose in that it may contain
entries for normal login access (e.g. HTTP, FTP or Telnet)
and entries for IPsec tunnels.
XAUTH Init Preshared Keys
Used when the remote peer is a Cisco device using
XAUTH and PSK authentication.
RSA Signatures
Select this option when the IPsec authentication will use
X.509 certificates.
XAUTH Init RSA
Used when the remote peer is a Cisco device using
XAUTH and X.509 certificates for authentication.
Our ID
When Aggressive mode is On, this parameter is a string of up to 20 characters. It is sent
to the remote peer to identify the initiator (e.g. the router). The variable %s can be used
in this parameter which will cause the router’s serial number to be sent. It can be
prefixed with other text if required.
When certificates are being used, this parameter should be configured with the “Altname”
field in a valid certificate held on the router.
Our ID type
This defines how the remote peer is to process the Our ID configuration.
IKE ID The Our ID parameter is a simple key ID (e.g. vpnclient1).
FQDN
The Our ID parameter is a Fully Qualified Domain Name (e.g.
vpnclient1.anycompany.com)
User FQDN
The Our ID parameter is a Fully Qualified Domain Name with a user
element (e.g.
joe.bloggs@anycompany.com)
IPv4 Address An IPv4 Address in dotted decimal notation.
Remote ID
When Aggressive mode is On, this parameter is a string of up to 20 characters which is
used to identify the remote peer. It should contain the same text as the Our ID
parameter in the remote peer’s configuration.
When Aggressive mode is Off, this parameter must be the IP address of the remote peer.
