Using DVCP to connect to devices• IP network addresses for the networks communicating with one another.• A common passphrase, known as a shared secret.• For WatchGuard VPN only, the local VPN IP address of each Firebox. It must beselected from a reserved network address that is not in use on either of thenetworks being connected. For more information, see RFC 1918 or “Setting UpNetwork Address Translation” on page 63.Both ends of the tunnel must use the same encryption method.Using DVCP to connect to devicesDynamic VPN Configuration Protocol (DVCP) is the WatchGuard-proprietaryprotocol that easily creates a virtual private network. The DVCP server is a Fireboxthat sits at the center of a distributed array of WatchGuard Firebox, SOHO, andSOHO|tc clients.How does DVCP work?The DVCP option causes the Firebox to act as a server. SOHOs can be DVCP clients,and Fireboxes can either be DVCP clients or servers. The DVCP server maintains theconnections between two devices by storing all policy information–includingnetwork address range and tunnel properties such as encryption, timeouts, andauthentication. DVCP clients can retrieve this information from the server. The onlyinformation clients need to maintain is an identification name, shared key, and the IPaddress of the server External interface.You use the the DVCP Client Wizard to configure a device as a DVCP server and thencreate tunnels to each client Firebox or SOHO. The clients then contact the server andautomatically download the information needed for them to connect securely.Basic and Enhanced DVCPWatchGuard offers two types of DVCP:Basic DVCP simplifies establishing VPN tunnels between SOHO units andFireboxes. It cannot manage tunnels between two Fireboxes.Enhanced DVCP manages tunnels between any two WatchGuard devices: SOHO toFirebox, Firebox to Firebox, and so on. Enhanced DVCP is available only if the VPNManager 2.0 option is installed.Creating a tunnel to a SOHO or SOHO|tcThe tunnels you create for SOHO clients must be completely distinct from any tunnelcreated for branch office VPN. In other words, no addresses in the DVCP client policyshould be in the same address range as any branch office policy.122
Using DVCP to connect to devicesNote also that if you configure a SOHO for both Basic and Enhanced DVCP, thegateway names must be different.From Policy Manager:1 Select Network => Branch Office VPN => Basic DVCP.The DVCP Configuration dialog box appears.2 Click Add.3 Enter a distinctive name for the DVCP client. Enter the shared key. Click Next.The client name appears in the DVCP Configuration dialog box as well as the Control CenterFirebox and Tunnel Status display.4 Enter the address range which the DVCP client will be able to access.5 Select a client type:Telecommuter IP AddressThe SOHO is assigned a single IP address. This is the device’s virtual IP addresson the Trusted network of the Firebox to which the device will be allowed access.SOHO Private NetworkThe SOHO is assigned an entire network.6 Click Next.7 Use the Type drop list to select an encryption type.Options include: ESP (Encapsulated Security Payload) or Authentication Only.8 Use the Authentication drop list to select an authentication method.Options include: None (no authentication), MD5-HMAC (128-bit algorithm), and SHA1-HMAC(160-bit algorithm).9 Use the Encryption drop list to select an encryption method.Options include: None (no encryption), DES-CBC (56-bit encryption), and 3DES-CBC (168-bitencryption).10 Enter values to set the interval to force key expiration. Enter traffic in kilobytesand/or time in hours.The default values are 8192 kilobytes or 24 hours.11 Click Next. Click Finish.The new policy appears in the DVCP Configuration dialog box. The WatchGuard device can nowbe connected, powered on, and configured. As part of the configuration process, it willautomatically download the appropriate tunnel information. You must provide the DVCP clientadministrator with the Client Name, shared key, and the server external interface IP address.Editing a tunnel to a deviceIt is possible to change the properties of a DVCP tunnel without adversely impactingthe DVCP client. Properties of a tunnel that you can modify without forcing the clientto reboot include:• Identification name• Shared key• Encryption/authentication level• TimeoutsYou can also change the network range of a WatchGuard client. However, when yousave the configuration to the server, it automatically triggers the client to reboot andload the new policy.User Guide 123
