DESCRIPTION
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 IP addresses must be static and correspond to the remote IPSec router's
configured remote IP addresses.
Two active SAs cannot have the local and remote IP address(es) both the same. Two
active SAs can have the same 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.
Press [SPACE BAR] to choose SINGLE, RANGE, or SUBNET and press [ENTER].
Select SINGLE with 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.
When the Addr Type field is configured to Single, enter a static IP address on the
LAN behind your Prestige.
When the Addr Type field is configured to Range, enter the beginning (static) IP
address, in a range of computers on your LAN behind your Prestige.
When the Addr Type is configured to SUBNET, this is a (static) IP address on the
LAN behind your Prestige.
When the Addr Type field is configured to Single, this field is N/A.
When the Addr Type field is configured to Range, enter the end (static) IP address,
in a range of computers on the LAN behind your Prestige.
When the Addr Type field is configured to SUBNET, this is a subnet mask on the
LAN behind your Prestige.
0 is the default and signifies any port. Type a port number from 0 to 65535. You
cannot create a VPN tunnel if you try to connect using a port number that does not
match this port number or range of port numbers.
Some of the most common IP ports are: 21, FTP; 53, DNS; 23, Telnet; 80, HTTP; 25,
SMTP; 110, POP3
Enter a port number in this field to define a port range. This port number must be
greater than that specified in the previous field. This field is N/A when 0 is configured
in the Port Start field.
Remote IP addresses must be static and correspond to the remote IPSec router's
configured local IP addresses. The remote fields are N/A when the Secure Gateway
Address field is configured to 0.0.0.0.
Two active SAs cannot have the local and remote IP address(es) both the same. Two
active SAs can have the same 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.
Press [SPACE BAR] to choose SINGLE, RANGE, or SUBNET and press [ENTER].
Select SINGLE with a single IP address. Use RANGE for a specific range of IP
addresses. Use SUBNET to specify IP addresses on a network by their subnet mask.
