* VLAN Trunking (ASA 5510, ASAOS 7.2.1)

Hey! If you are trying to trunk VLAN 1, you are going to run into trouble (using the below config, I think you may have to configure Ethernet0/3 (NOT a sub-interface) to have an ip address. You will not be able to type in ‘vlan 1’, as it is assumed). You have been warned.
