Chapter 14: Configuring Virtual Private Networks Configuring client address pools Configuring the Servers tab Adding or modifying a server 412 The Servers tab is used to define the DNS server(s) and/or the WINS server(s) that will be made available to remote clients. These servers provide name and address resolution services for devices within the local network. The DNS servers you specify can reside on the Sidewinder G2 or be located on another machine in a local or remote network. WINS servers are never located on the Sidewinder G2. To configure the Servers tab, follow the steps below. 1 The DNS Servers box lists the DNS servers that will be made available to VPN clients that establish a connection using an address from the client address pool. The following options are available: • New—Click this button to create a new DNS server. See “Adding or modifying a server” for details. • Modify—Select a DNS server and click Modify to modify an existing DNS server. See “Adding or modifying a server” for details. • Delete—Select the DNS server and click Delete to delete an existing DNS server. 2 The NBNS/WINS Servers box lists the NBNS and WINS servers that will be made available to VPN clients that establish a connection using an address from the client address pool. The following options are available: • New: Click this button to create a new NBNS/WINS server. See “Adding or modifying a server” on page 412 for details. • Modify: Select a NBNS/WINS server and click Modify to modify an existing NBNS/WINS server. See “Adding or modifying a server” on page 412 for details. • Delete: Select the NBNS/WINS server and click Delete to delete an existing NBNS/WINS server. To add or modify a server entry in the New/Modify DNS or NBNS/WINS server window, follow the steps below. 1 In the DNS Server or NBNS/WINS field, type or change the IP address that specifies the location of the DNS or WINS server. 2 Click Add to add the IP address to the server list. 3 Repeat step 1 and step 2 for each additional IP address you want to add. 4 When you are finished adding/modifying IP addresses, click Add. 5 To save changes to the Servers tab, click the Save icon.
Figure 178: Client Address Pools: Fixed IP Map tab About the Fixed IP Map tab Configuring the fixed IP map Chapter 14: Configuring Virtual Private Networks Configuring client address pools To configure the fixed IP map, select VPN Configuration > Client Address Pools. Create a new entry or select an existing one, and then select the Fixed IP Map tab. The following window appears. The Fixed IP Map tab is used to define fixed addresses for selected clients. It enables each of the specified clients to connect to the Sidewinder G2 using their own unique IP address. It effectively reserves a specific IP address for a specified client. The fixed addresses you specify must be within the range of available IP address as defined by the client address pools. Caution: Do not use network or broadcast addresses when mapping IP addresses to client IDs. These addresses are reserved and are not considered valid values for client address mappings. For example, if your address range is 192.168.105.0/24, then 192.168.105.0 (the network address) and 192.168.105.255 (the broadcast address) should not be used in a fixed IP client mapping. The network address is that address whose masked portion is all 0s, and the broadcast address is that address whose masked portion is all 1s. One of the benefits of assigning fixed IP addresses to selected clients is that it allows you to govern what each client can do. For example, you might restrict access to certain clients, and you might grant additional privileges to other clients. You do this by creating a network object for a selected IP address and then using the network object within a rule. The Fixed IP Map tab contains a Fixed IP Client Address Mappings box that lists the current IP address/client mappings. Each unique IP address can appear in the table only once. Multiple identities representing a single client, however, can be mapped to one IP address. You can add, modify, or delete entries by using one of the buttons described below. 413
