LABEL DESCRIPTION
IPSec Setup
Active Select this check box to activate this VPN policy.
Name Type up to 32 characters to identify this VPN policy. You may use any character,
including spaces, but the Prestige drops trailing spaces.
IPSec Key Mode Select IKE or Manual from the drop-down list box. Manual is a useful option for
troubleshooting if you have problems using IKE key management.
SPI Type a number (base 10) from 1 to 999999 for the Security Parameter Index.
Encapsulation Mode Select Tunnel mode or Transport mode from the drop-down list box.
DNS Server (for
IPSec VPN)
If there is a private DNS server that services the VPN, type its IP address here. The
Prestige assigns this additional DNS server to the Prestige's DHCP clients that have
IP addresses in this IPSec rule's range of local addresses.
A DNS server allows clients on the VPN to find other computers and servers on the
VPN by their (private) domain names.
Local Local IP addresses must be static and correspond to the remote IPSec router's
configured remote IP addresses.
Two active SAs can have the same configured local or remote IP address, but not
both. You can configure multiple SAs between the same local and remote IP
addresses, as long as only one is active at any time.
In order to have more than one active rule with the Secure Gateway Address field
set to 0.0.0.0, the ranges of the local IP addresses cannot overlap between rules.
If you configure an active rule with 0.0.0.0 in the Secure Gateway Address field and
the LAN’s full IP address range as the local IP address, then you cannot configure
any other active rules with the Secure Gateway Address field set to 0.0.0.0.
Local Address Type Use the drop-down menu to choose Single, Range, or Subnet. Select Single for a
single IP address. Select Range for a specific range of IP addresses. Select Subnet
to specify IP addresses on a network by their subnet mask.
