DESCRIPTION
Remote IP addresses must be static and correspond to the remote IPSec
router's configured local IP addresses. The remote address fields do not apply
when the Secure Gateway Address field is configured to 0.0.0.0. In this case
only the remote IPSec router can initiate the VPN.
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.
Enter a (static) IP address on the network behind the remote IPSec router.
When the remote IP address is a single address, type it a second time here.
When the remote IP address is a range, enter the end (static) IP address, in a
range of computers on the network behind the remote IPSec router.
When the remote IP address is a subnet address, enter a subnet mask on the
network behind the remote IPSec router.
0 is the default and signifies any port. Type a port number from 0 to 65535.
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 (or equal to it for configuring
an individual port).
Enter the WAN IP address of your Prestige. The Prestige uses its current
WAN IP address (static or dynamic) in setting up the VPN tunnel if you leave
this field as 0.0.0.0. The VPN tunnel has to be rebuilt if this IP address
changes.
Select IP to identify this Prestige by its IP address.
Select DNS to identify this Prestige by a domain name.
Select E-mail to identify this Prestige by an e-mail address.
When you select IP in the Local ID Type field, type the IP address of your
computer in the local Content field. The Prestige automatically uses the IP
address in the My IP Address field (refer to the My IP Address field
description) if you configure the local Content field to 0.0.0.0 or leave it blank.
It is recommended that you type an IP address other than 0.0.0.0 in the local
Content field or use the DNS or E-mail ID type in the following situations.
• When there is a NAT router between the two IPSec routers.
• When you want the remote IPSec router to be able to distinguish between
VPN connection requests that come in from IPSec routers with dynamic
WAN IP addresses.
When you select DNS or E-mail in the Local ID Type field, type a domain
name or e-mail address by which to identify this Prestige in the local Content
field. Use up to 31 ASCII characters including spaces, although trailing spaces
are truncated. The domain name or e-mail address is for identification
purposes only and can be any string.
Type the WAN IP address or the URL (up to 31 characters) of the remote
secure gateway with which you're making the VPN connection. Set this field to
0.0.0.0 if the remote secure gateway has a dynamic WAN IP address (the
IPSec Keying Mode field must be set to IKE).
Select IP to identify the remote IPSec router by its IP address.
Select DNS to identify the remote IPSec router by a domain name.
Select E-mail to identify the remote IPSec router by an e-mail address.
