Chapter 13 VPN Screens

Remote

Remote IP addresses must be static and correspond to the remote IPSec router's 

configured local IP addresses. The remote fields do not apply when the Secure 

Gateway IP 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.

Remote Address

Type

Use the drop-down menu to choose Single, Range, or Subnet. 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.

IP Address Start When the Remote Address Type field is configured to Single, enter a (static) IP 

address on the network behind the remote IPSec router. When the Remote 

Address Type field is configured to Range, enter the beginning (static) IP 

address, in a range of computers on the network behind the remote IPSec router. 

When the Remote Address Type field is configured to Subnet, enter a (static) IP 

address on the network behind the remote IPSec router. 

End / Subnet Mask When the Remote Address Type field is configured to Single, this field is N/A. 

When the Remote Address Type field is configured to Range, enter the end 

(static) IP address, in a range of computers on the network behind the remote 

IPSec router. When the Remote Address Type field is configured to Subnet, 

enter a subnet mask on the network behind the remote IPSec router. 

Address 

Information

Local ID Type Select IP to identify this ZyXEL Device by its IP address. 

Select DNS to identify this ZyXEL Device by a domain name.

Select E-mail to identify this ZyXEL Device by an e-mail address.

Content When you select IP in the Local ID Type field, type the IP address of your 

computer in the local Content field. The ZyXEL Device 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 ZyXEL Device 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.

My IP Address Enter the WAN IP address of your ZyXEL Device. The VPN tunnel has to be 

rebuilt if this IP address changes.
The following applies if this field is configured as 0.0.0.0:
The ZyXEL Device uses the current ZyXEL Device WAN IP address (static or 

dynamic) to set up the VPN tunnel. 
If the WAN connection goes down, the ZyXEL Device uses the dial backup IP 

address for the VPN tunnel when using dial backup or the LAN IP address when 

using traffic redirect. See the chapter on WAN for details on dial backup and traffic 

redirect.
