This Router supports IPSec, PPTP, and PPPoE Passthrough. You can select either Enable or Disable for these options.
VPN
Select Tunnel Entry- Select the tunnels number you want to set up.
Delete- click this to remove any entries made for this tunnel you selected.
Summary- Click this button to display the status of all the tunnels.
IPSec VPN Tunnel- Select Enabled to create a tunnel or Disabled to close the tunnel.
Tunnel Name- Once the tunnel is enabled, enter an arbitrary name for the tunnel you are about to create.
Local Secure Group
This allows you to grant local computer access to this tunnel.
| Subnet | This will allow all computers on the local subnet to access the tunnel. Enter the IP Address and Mask to allow access to the tunnel. |
| IP Addr. | This only allows the local computer with the specified IP address. Enter the IP address you want to allow access to the tunnel. |
| IP Range | This allows a range of local computers to access the tunnel. Enter the IP address range allowed to access the tunnel. |
Remote Secure Group
This allows you grant remote computers access to this tunnel.
| Subnet | This will allow all computers on the remote subnet to access the tunnel. Enter the IP Address and Mask to allow access to the tunnel. |
| IP Addr. | This only allows the remote computer with the specified IP address. Enter the IP address you want to allow access to the tunnel. |
| IP Range | This allows a range of remote computers to access the tunnel. Enter the IP address range allowed to access the tunnel. |
| Host | When this is selected, the settings will be the same as the Remote Security Gateway. |
| Any | This option will allow any IP address from a remote location to access this tunnel. |
Remote Secure Gateway
This sets the remote end of the VPN tunnel. You can either specify the IP address, Domain, or Any.
| IP Addr. | Enter the IP address of the remote tunnel you will connect. |
| Domain | This option lets you enter the fully qualified domain name. If you do not have an IP address, you have an option to enter the domain of the tunnel you are connecting to. |
| Any | This will will allow any tunnel connection to be established. |
Encryption
| DES | Data Encryption Standard (DES) is a type of encryption for this VPN tunnel. If you select this option, make sure the other end of the tunnel uses the same encryption type. |
| 3DES | Triple Data Encryption Standard (3DES) is a stronger type of encryption for this VPN Tunnel. If you select this option, make sure the other end of the tunnel uses the same encryption type. |
| Disable | This option will not encrypt for this tunnel. |
Authentication
| MD5 | Message-Digest Algorithm (MD5)- Generates 128-bit message digest based on the input. If you select this option, make sure the other end of the tunnel uses the same authentication type. |
| SHA | Secure Hash Algorithm (SHA)- Generates 160-bit message digest based on the input. If you select this option, make sure the other end of the tunnel uses the same authentication type. |
| Disabled | This option will not authenticate for this tunnel. |
Key Management
In order for any encryption to occur, the two ends of the tunnel must agree on the type of encryption. This is done by sharing a "key" to encrypt code. You can select Auto (IKE) or Manual.
Automatic Key Management
| PFS | Perfect Forward Secrecy (PFS) ensures that the initial key exchange and IKE proposal are secure. This must be the same for both end of the tunnel. |
| Pre-shared Key | Enter a series of number and letters that will be used as your key. This must be the same for both end of the tunnel. |
| Key Lifetime | Enter a number of seconds for the life of the key. After the key lifetime expires, a new code will be generated. This much be the same for both end of the tunnel. |
Manual Key Management
| Encryption key | Enter a series of letters or numbers to generate an encryption key. This must be the same for both end of the tunnel. |
| Authentication Key | Enter a series of letters or numbers to generate an authentication key. This must be the same for both end of the tunnel. |
| Inbound SPI | Enter a series of letter or numbers to generate the Inbound SPI. This must match the outbound SPI on the other end of the tunnel. |
| Outbound SPI | Enter a series of letter or numbers to generate the outbound SPI. This must match the inbound SPI on the other end of the tunnel. |
Status- This will shows if you are connected or disconnected from the other end of the VPN tunnel.
Connect/Disconnect- This button will connect or disconnect the other end of the VPN tunnel.
View Log- This will show you the VPN activity when connecting and disconnecting.
Advanced Settings
Phase 1 is used to create a Security Association (SA), often called the IKE SA. After Phase 1 is completed, Phase 2 is used to create one or more IPSec SAs, which are then used to key IPSec sessions.
Operation Mode
| Main | This is for normal operation and is more secure. |
| Aggressive | This is faster and less secure. |
| Username | Some require username to establish a VPN connection. |
| Encryption | Select the length of the key used to encrypt/decrypt ESP packets. There are two choices: DES and 3DES. 3DES is recommended for security. |
| Authentication | Select the method used to authenticate ESP packets. There are two choices: MD5 and SHA. SHA is recommended for security. |
| Group | There are two Diffie-Hellman Groups to choice from: 768-bit and 1024-bit. Diffie-Hellman refers to a cryptographic technique that uses public and private keys for encryption and decryption. |
| Key Lifetime | Enter a number of seconds for the life of the key.After the key lifetime expires, a new code will be generated. This much be the same for both end of the tunnel. |
Phase 2
| Group | There are two Diffie-Hellman Groups to choice from: 768-bit and 1024-bit. Diffie-Hellman refers to a cryptographic technique that uses public and private keys for encryption and decryption. |
| Key Lifetime | Enter a number of seconds for the life of the key.After the key lifetime expires, a new code will be generated. This much be the same for both end of the tunnel. |
Other Setting
| NetBIOS broadcast | Check this to enable NetBIOS traffic to pass-through the VPN tunnel. |
| Anti-replay | Check this to enable the Anti-reply protection. this feature keeps track of sequence numbers and packet arrival, ensuring security at the IP packet-level. |
| Keep-Alive | Check this to re-establish VPN tunnel connection whenever it is dropped. Once the tunnel is initialized, this feature will keep the tunnel connected. |
| If IKE failed more than x Times, block this unauthorized IP for y seconds. | Check this box to block unauthorized IP addresses. Complete the on-screen sentence to specify how many times IKE must fail before blocking that unauthorized IP address for a length of time that you specify (in seconds). |
Rtfm?
It really depends on what your options are in the vpn device are.

---------------------------------------------------I need to take my laptop on several road trips, and I need to connect back to my home office LAN - all Debian machines. I am on COX cable with a BEFSX41 router. The BEFSX41 has a VPN option that I have never used. What do I need to add to my laptop (Debian) to talk to my home office LAN securely (ie through a VPN) using my BEFSX41? Obviously, I am a complete nube when it comes to setting up VPN access to my LAN. I have googled for some recommendations, but I have not found a good reference to follow.
Thanks,
