Configuration System IP Routing DHCP

Configuration System IP Routing DHCP

This screen lets you configure DHCP (Dynamic Host Configuration Protocol) server parameters that apply to DHCP server functions within the VPN 3002.

The DHCP server for the private interface lets IP hosts in its network automatically obtain IP addresses from a limited pool of addresses for a fixed length of time, or lease period. Before the lease period expires, the VPN 3002 displays a message offering to renew it. If the lease is not renewed, the connection terminates when the lease expires, and the IP address becomes available for reuse. Using DHCP simplifies configuration since you do not need to know what IP addresses are considered valid on a particular network.

Enabled

Check the box to enable the DHCP server functions on the VPN 3002. The box is checked by default. To use DHCP address assignment, you must enable DHCP functions here.

Lease Timeout

Enter the timeout in minutes for addresses that are obtained from the DHCP server. Minimum is 5, default is 120, maximum is 500000 minutes. DHCP servers “lease” IP addresses to clients on the VPN 3002 private network for this period of time.

The Lease Timeout period you configure applies only when the tunnel to the VPN Concentrator is established. When the tunnel is not established, the Lease Timeout period is 5 minutes.

Address Pool Start/End

Enter the range of IP addresses that the DHCP server can assign. Use dotted decimal notation. The default is 127 successive addresses, with the first address being the address immediately after that of the private interface. The maximum number of addresses you can configure is 127.
