1 IPSec Pass through via Gateway to Gateway VPN Connection 1. Connection 2 In the diagram depicted below, the left side router represents the SME200/SME100/SME50 in HQ and right side represents the PC installed VPN Client Software at Home which is behind the Home Router with IPSec Pass Through. SME200/SME100/SME50 in HQ (Left-side) IP = A.A.A.A (Fixed IP) Local Secure Subnet = ; Subnet Mask = Security Type = (IP only) SME200/SME100/SME50 or Home Gateway or Router at Home (Right-side) IP = Dynamic IP (PPPoE) IPSec pass through enable PC with SafeNet Client Software at Home (Right-side) IP = Dynamic IP or Fixed IP (actually, don t care) Security Type = (Dynamic IP + Addr. (USER FQDN) Authentication) 1

3 2. Settings for SME200/SME100/SME50 in HQ 2.1 Basic Settings 1. The tunnel number will be generated automatically, and create a tunnel name. In here, we use Left as a tunnel name. 2. If we are creating the VPN tunnel via WAN1 3. Enable check-box is a option for users if this tunnel will be enable (working) or disable (not working) 2.2 Local Group Settings Note: All the types selected should be same with the Remote setting of PC installed with SafeNet at Home. (Right-side). 1. Select the Local Security Gateway Type as IP Only, and IP address will be shown automatically. (SME200/SME100/SME50 can detect its IP address) 2. Select the Local Security Group Type. There are three types of local security group: IP, Subnet and IP range. Select the local security group type as Subnet and enter the IP address and Subnet Mask. 2.3 Remote Group Settings Note: All the types selected should be the same as My Identify setting of PC installed with SafeNet 3

4 at Home (Right-side. ) 1. Because the IP of Home Router with IPSec pass through is Dynamic IP, select the Dynamic IP + Addr. (USER FQDN) Authentication for remote security gateway type 2. address (USER FQDN) is charles@vpn_player.com, for example 3. There are three types of remote security group: IP, Subnet and IP range. Select the type as IP and enter the IP address of PC installed with SafeNet at Home (Right Side) 2.4 IPSec Settings Note: All the parameters we are going to set have to be the same as the setting of PC with SafeNet at Home. (Right-side) For example, we are using IKE with Pre-shared key, Phase1/2 DH group is Group1, Phase1/2 Encryption is DES, Phase1/2 Authentication is MD5, Phase1 SA Life Time is seconds Phase2 SA Life Time is 3600 seconds Pre-shared Key is secretkey To increase the security level, we can enable PFS (Perfect Forward Secrecy). If PFS box is checked, SME200/SME100/SME50 will periodically regenerate (every 3600 seconds Phase2 SA Life Time) Gold Key based on pre-shared key. 4
