Initial Setup in Routing Mode
Deploying the TMS zl Module
VLANs Not Assigned to a Zone
Often, your plan for zones calls for assigning every VLAN in your LAN to a
zone. However, you can choose to have non-TMS VLANs. The host switch
would typically be the default router for these VLANs.
If you want devices in TMS VLANs to be able reach these VLANs, choose one
of them to be a TMS VLAN. Allow the switch to have an IP address on this
VLAN. Then create a route on the TMS zl Module to the non-TMS VLANs that
uses that host switch IP address as the gateway. On the host switch, create a
route to the TMS VLANs; the gateway is the TMS zl Module IP address on the
VLAN on which both the module and the switch have addresses.
The TMS zl Module filters and controls traffic that passes between the TMS
VLANs and the non-TMS VLANs and vice versa. The module also controls all
traffic that is routed between TMS VLANs. However, the module does not filter
or control traffic that is routed between non-TMS VLANs.
Figure 2-4 shows an example.
