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-pool poolname {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.
