Billion BiPAC 8500/8501/8520/8521 SHDSL (VPN) Firewall Bridge/ Router

IPSec VPN Connection (BiPAC 8500/ 8501/ 8520 Only)

•Connection Name: User-defined name for the connection (e.g. “connection to office”).

•Local Network: Set the IP address, subnet or address range of the local network.

oSingle Address: The IP address of the local host.

oSubnet: The subnet of the local network. For example, IP: 192.168.1.0 with netmask 255.255.255.0 specifies one class C subnet starting from 192.168.1.1 (i.e. 192.168.1.1 through to 192.168.1.254).

oIP Range: The IP address range of the local network. For example, IP:

192.168.1.1, end IP: 192.168.1.10.

•Remote Secure Gateway Address (or Domain Name): The IP address or hostname of the remote VPN device that is connected and is used to establishe a VPN tunnel.

•Remote Network: Set the IP address, subnet or address range of the remote network.

•Proposal: Select the IPSec security method. There are two methods of checking the authentication information, AH (authentication header) and ESP (Encapsulating Security Payload). Use ESP for greater security so that data will be encrypted and authenticated. Using AH data will be authenticated but not encrypted.

•Authentication: Authentication establishes the integrity of the datagram and ensures that it is not tampered with during transmission. There are three options, Message Digest 5 (MD5), Secure Hash Algorithm (SHA1) or NONE. SHA1 is more resistant to brute-force attacks than MD5, however it is slower.

oMD5: A one-way hashing algorithm that produces a 128−bit hash.
