Motorola 7.7.4 manual 108

When configuring VLANs you must define how traffic needs to be forwarded:

•If traffic needs to be bridged between LAN and WAN you can create a single VLAN that encompasses the WAN port and LAN ports.

•If traffic needs to be routed then you must define four elements:

•LAN-side VLANs

•WAN-side VLANs

•Associate IP Interfaces to VLANs

•Inter-VLAN Routing Groups: configuration of routing between VLANs is done by associ- ation of a VLAN to a Routing Group. Traffic will be routed between VLANs within a rout- ing group. The LAN IP Ethernet Interface can be bound to multiple LAN VLANs, but forwarding can be limited between an Ethernet LAN port and a WAN VLAN if you properly configure Inter-VLAN groups.

Inter-VLAN groups are also used to block routing between WAN interfaces. If each WAN IP interface is bound to its own VLAN and if you configure a different Inter-VLAN group for each WAN VLAN then no routing between WAN IP interfaces is possible.

•Example: to route between a VCC and all the LAN ports, which effectively is similar to the default configuration without any VLANs:

Create a VLAN named “VccWan” consisting of vcc1, ip-vcc1, routing-group 1

Create a VLAN named “Lan” consisting of eth0.1, eth0.2, eth0.3, eth0.4, ssid1, ssid2, ssid3, ssid4 (etc.), ip-eth-a, routing-group 1
