Configuring
Network Address
Translation
/protocol/nat/set scope <index (1-8)>
dhcp-server {untagged | vlan <vlan_id>}
based-ip <IP_addr>
lease-time <minutes>
This command lets you configure the NAT settings for each address scope.
The
dhcp-server
setting lets you specify which VLAN traffic to associate to the
scope. The
untagged
setting specifies that the scope applies only to untagged
traffic. The
vlan <VLAN ID>
settings specifies that the scope applies only to
traffic with that VLAN ID. VLAN IDs cannot be shared across different scopes.
The default setting is
untagged
. Refer to
“Layer 2 Network Configuration” on
for more information on VLAN configuration.
The
based-ip
setting lets you specify the base IP address for the scope. Use
xx.xx.xx.0 as the format. Once specified, the BelAir100SN IP address becomes
xx.xx.xx.1 and it begins to allocate addressed from xx.xx.xx.2 to xx.xx.xx.254.
The
lease-time
setting lets you specify the maximum DHCP lease time in
minutes for IP addresses supplied by NAT. The default is 60 minutes. Other
DHCP server settings are based on those specified in
.
By default, scope 1 is preconfigured for untagged VLAN traffic with a base IP
address of 192.168.5.0.
