IP Addressing

DHCP

Creating DHCP Pools

Subscribers who use protocols that are not NAT-friendly (including some gaming servers) or who use a dynamic DNS service to act as a Web server may want to have a non-NATed real DHCP address.

Subscribers who want this service must have DHCP enabled on their local PCs. If they do not have DHCP enabled, they receive the normal NATed service and do not benefit from having a real IP address.

To create a DHCP pool, use the following command:

dhcp-poolpoolname {start_ip end_ip netmask} [lease mins lease spec delete]

For example, to create a dhcp-pool called swim starting at 123.123.123.99 and ending at 123.123.123.136, with a subnet mask 255.255.255.0 and a duration of one day, type:

sms2000% dhcp-pool swim 123.123.123.99 123.123.123.136 255.255.255.0 lease 1440

Removing a DHCP Assignment

To remove a DHCP assignment with a specified hexadecimal MAC address, use the following command:

dhcp-server release mac_address

For example, to release a DHCP entry with MAC address 0001030465DB, type:

sms2000% dhcp-server release 0001030465DB

Note: The MAC address is presented in the format 0001030465DB (with no separators).

DNS

Setting the DNS Server Address

DNS servers allow the SMS2000 to convert a name such as www.tutsystems.com to an IP address such as 208.186.133.55. You can configure multiple DNS servers by entering this command once for each server.
