The router supports IPSec VPN to establish secure, end-to-end private network connections 
over a public networking infrastructure.  

 
Connection Name: A 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. 

•  Single Address: The IP address of the local host. 
•  Subnet: 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). 

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

192.168.1.1, end IP:192.168.1.10 

•  Secure Gateway Address (or Domain Name): The IP address or hostname of the 

remote VPN device that is connected and establishes a VPN tunnel. 

•  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 

it is not tampered with in transmit. 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. 

1.  MD5: A one-way hashing algorithm that produces a 128−bit hash. 
2.  SHA1: A one-way hashing algorithm that produces a 160−bit hash. 

Encryption: Select the encryption method from the pull-down menu. There are several
