You can repeat configuration on ethernet 0/1 to other interfaces to assign VLAN 1.Īfter assigning ethernet 0/1 to ethernet 0/7 as your LAN ports, then you need to enable DHCP to assign IP for each port. In this example, I configured my internet connection (VLAN 100) on port ethernet 0 and other ports are assigned for my LAN (VLAN 1). The name of VLAN 1 is inside and the name for VLAN 100 is outside.Īfter creating VLANs, you can continue by assigning the created VLANs to desired interfaces. In this example, I configured VLAN 1 for my LAN and VLAN 100 for my internet connection.
Configuring Cisco ASA 5505 as your home or small business internet gateway is not that hard.
