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-net configures 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-net start_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
