IP Addressing

For example, to set the IP type to DHCP, type:

sms2000% iptype DHCP

Source-Nets

Setting a Source-Net

Note: Source nets are only used with IP types 1 to 1 and 1 to 1 unique.

The command set source-netconfigures a source-net. A source-net is a SMS2000 configured subnet to which subscriber connections are mapped when using the 1 to 1 and 1 to 1 unique IP types. For IP types 1to1 and 1to1Unique subscribers are each given one of the available IP addresses. If there are enough source-net addresses, each subscriber is given a real address.

Note: There can be only one source-net configured for a given group.

Note: The start address must be less than or equal to the end address and should not overlap a DHCP pool address range.

Note: The OCS and SMS2000 can work together to provide non-NATed service to subscribers who are either assigned a permanent real IP address or given an address from an OCS-defined DHCP pool. This is NOT the same as the source-net feature. Use non-NATed addresses in cases where the subscriber wants to run a server (such as a Web server) or use a protocol (such as a gaming server) that is not NAT-friendly. For information on DHCP, see “DHCP Pools” on page 70, Chapter 11.

To add a source-net or IP address range in the real network to which client addresses are translated, use this command:

set source-netstart_address end_address subnet-mask

For example, to have all subscribers now appear with IP addresses from the configured source-net, type:

sms2000% set source-net 123.123.123.10 123.123.123.100 255.255.255.128

Deleting a Configured Source-Net

To delete a configured source-net, use this command:

delete source-net

For example, to delete a configured source-net, type:

sms2000% delete source-net
