Using the MAR3200 in Mobile Environments
The threshold sets the level at which the algorithm is triggered to scan for a better parent. This threshold
should be set to noise+20dBm but not more than -70dBm (+70 because input for threshold is positive).
The default is -70 dBm.

The default is -70 dBm.
Using Network Address Translation (NAT) with the MAR3200
Without the use of Mobile IP, devices connected to the MAR3200 will need to use NAT and static routing
to route traffic. On the MAR3200 create a subnet for clients to connect to and NAT that subnet to the
WMIC interface. For return traffic destined to devices or clients attached to the MAR3200 create static
route pointing back to the MARs WMIC interface on a router connecting to the mesh WLC.
to route traffic. On the MAR3200 create a subnet for clients to connect to and NAT that subnet to the
WMIC interface. For return traffic destined to devices or clients attached to the MAR3200 create static
route pointing back to the MARs WMIC interface on a router connecting to the mesh WLC.
To configure NAT and static routing, refer to
and perform the following steps (assuming you
already configured the WMIC Universal Bridge Client and Mesh network).
Perform the following steps from the router’s global configuration mode:
Step 1
Create a VLAN for MAR connected clients:
MR(config)# int vlan 5
MR(config-if)# ip address 10.10.10.1 255.255.255.0
Step 2
Configure a DHCP pool to be used for connecting clients to the MAR:
MR(config)# ip dhcp pool CLIENTPOOL
MR(dhcp-config)# network 10.10.10.0 255.255.255.0
MR(dhcp-config)# default-router 10.10.10.1
MR(config)# ip dhcp excluded-address
MR(config)# ip dhcp excluded-address 10.10.10.1
Step 3
Using the following commands, configure NAT for that pool so that it uses the VLAN interface for the
WMIC that connects to the Mesh network:
WMIC that connects to the Mesh network:
MR(config)# ip nat inside source list 10 interface Vlan4 overload
!
MR(config)# access-list 10 permit 10.10.10.0 0.0.0.255 log
Step 4
Label your inside and outside NAT interfaces:
MR(config)# interface Vlan4
MR(config-if)# ip address 10.20.42.1 255.255.255.0
MR(config-if)# ip nat outside
!
MR(config)# interface Vlan5
MR(config-if)# ip address 10.10.10.1 255.255.255.0
MR(config-if)# ip nat inside
Step 5
Configure a default gateway on the MAR that points to the Mesh network:
MR(config)# ip default-gateway 10.20.41.1
Step 6
Save the configuration on the MAR3200 and exit:
MR# wr mem
MR# exit
Step 7
Log on to Router1 and configure static routing (see
for static routes):
Router1(config)# ip route
