P-202H Plus v2 User's Guide Table 100 Menu 27.1 IPSec Summary FIELD DESCRIPTION Local Addr Start When the Addr Type field in Menu 27.1.1 IPSec Setup is configured to SINGLE, this is a (static) IP address on the LAN behind your ZyXEL Device. When the Addr Type field in Menu 27.1.1 IPSec Setup is configured to RANGE, this is the beginning (static) IP address, in a range of computers on the LAN behind your ZyXEL Device. When the Addr Type field in Menu 27.1.1 IPSec Setup is configured to SUBNET, this is a (static) IP address on the LAN behind your ZyXEL Device. Local Addr End / Mask When the Addr Type field in Menu 27.1.1 IPSec Setup is configured to SINGLE, this is the same (static) IP address as in the Local Addr Start field. When the Addr Type field in Menu 27.1.1 IPSec Setup is configured to RANGE, this is the end (static) IP address, in a range of computers on the LAN behind your ZyXEL Device. When the Addr Type field in Menu 27.1.1 IPSec Setup is configured to SUBNET, this is a subnet mask on the LAN behind your ZyXEL Device. Encap This field displays Tunnel mode or Transport mode. See earlier for a discussion of these. You need to finish configuring the VPN policy in menu 27.1.1.1 or 27.1.1.2 if ??? is displayed. IPSec Algorithm This field displays the security protocols used for an SA. ESP provides confidentiality and integrity of data by encrypting the data and encapsulating it into IP packets. Encryption methods include 56-bit DES and 168-bit 3DES. NULL denotes a tunnel without encryption. AH (Authentication Header) provides strong integrity and authentication by adding authentication information to IP packets. This authentication information is calculated using header and payload data in the IP packet. This provides an additional level of security. AH choices are MD5 (default - 128 bits) and SHA -1(160 bits). Both AH and ESP increase the ZyXEL Device's processing requirements and communications latency (delay). You need to finish configuring the VPN policy in menu 27.1.1.1 or 27.1.1.2 if ??? is displayed. Key Mgt This field displays the SA's type of key management, (IKE or Manual). Remote Addr Start When the Addr Type field in Menu 27.1.1 IPSec Setup is configured to SINGLE, this is a static IP address on the network behind the remote IPSec router. When the Addr Type field in Menu 27.1.1 IPSec Setup is configured to RANGE, this is the beginning (static) IP address, in a range of computers on the network behind the remote IPSec router. When the Addr Type field in Menu 27.1.1 IPSec Setup is configured to SUBNET, this is a static IP address on the network behind the remote IPSec router. This field displays N/A when you configure the Secure Gateway Addr field in SMT 27.1.1 to 0.0.0.0. Remote Addr End / Mask When the Addr Type field in Menu 27.1.1 IPSec Setup is configured to SINGLE, this is the same (static) IP address as in the Remote Addr Start field. When the Addr Type field in Menu 27.1.1 IPSec Setup is configured to RANGE, this is the end (static) IP address, in a range of computers on the network behind the remote IPSec router. When the Addr Type field in Menu 27.1.1 IPSec Setup is configured to SUBNET, this is a subnet mask on the network behind the remote IPSec router. This field displays N/A when you configure the Secure Gateway Address field in SMT 27.1.1 to 0.0.0.0. Secure GW Addr This is the WAN IP address or the domain name (up to the first 15 characters are displayed) of the IPSec router with which you are making the VPN connection. This field displays 0.0.0.0 when you configure the Secure Gateway Address field in SMT 27.1.1 to 0.0.0.0. Chapter 33 VPN/IPSec Setup 302
