Chapter 24 IPSec VPN Each field is described in the following table. Table 126 Configuration > VPN > IPSec VPN > VPN Gateway > Edit LABEL Show Advance Settings / Hide Advance Settings General Settings VPN Gateway Name Gateway Settings My Address DESCRIPTION Click this button to display a greater or lesser number of configuration fields. Type the name used to identify this VPN gateway. You may use 1-31 alphanumeric characters, underscores(_), or dashes (-), but the first character cannot be a number. This value is case-sensitive. Select how the IP address of the ISG50 in the IKE SA is defined. If you select Interface, select the Ethernet interface, VLAN interface, virtual Ethernet interface, virtual VLAN interface or PPPoE/PPTP interface. The IP address of the ISG50 in the IKE SA is the IP address of the interface. Peer Gateway Address If you select Domain Name / IP, enter the domain name or the IP address of the ISG50. The IP address of the ISG50 in the IKE SA is the specified IP address or the IP address corresponding to the domain name. 0.0.0.0 is invalid. Select how the IP address of the remote IPSec router in the IKE SA is defined. Select Static Address to enter the domain name or the IP address of the remote IPSec router. You can provide a second IP address or domain name for the ISG50 to try if it cannot establish an IKE SA with the first one. Authentication Select Dynamic Address if the remote IPSec router has a dynamic IP address (and does not use DDNS). Note: The ISG50 and remote IPSec router must use the same authentication method to establish the IKE SA. Pre-Shared Key Certificate Select this to have the ISG50 and remote IPSec router use a pre-shared key (password) to identify each other when they negotiate the IKE SA. Type the pre-shared key in the field to the right. The pre-shared key can be • 8 - 32 alphanumeric characters or 8 - 32 pairs of hexadecimal (0-9, A-F) characters, preceded by "0x". If you want to enter the key in hexadecimal, type "0x" at the beginning of the key. For example, "0x0123456789ABCDEF" is in hexadecimal format; in "0123456789ABCDEF" is in ASCII format. If you use hexadecimal, you must enter twice as many characters since you need to enter pairs. The ISG50 and remote IPSec router must use the same pre-shared key. Select this to have the ISG50 and remote IPSec router use certificates to authenticate each other when they negotiate the IKE SA. Then select the certificate the ISG50 uses to identify itself to the remote IPsec router. This certificate is one of the certificates in My Certificates. If this certificate is self-signed, import it into the remote IPsec router. If this certificate is signed by a CA, the remote IPsec router must trust that CA. Note: The IPSec routers must trust each other's certificates. The ISG50 uses one of its Trusted Certificates to authenticate the remote IPSec router's certificate. The trusted certificate can be a self-signed certificate or that of a trusted CA that signed the remote IPSec router's certificate. 382 ISG50 User's Guide
