Setting up an ASA 5505

So I setup my first Cisco ASA.  This what I did...

First off this device has 8 Ports.  Ports Ethernet 0/1-7 are the switch ports on the device and the Ethernet 0/0 is the outside interface that will connect to your ISP.  This needs to be set for DHCP unless your ISP requires you to set a static IP.  That static IP would be given to you from your ISP.

Basically follow the guides that come with the ASA.  They will get you to setup everything up to get you started.

First thing is you should go to  This will bring you to a page that allows you to download the ASDM software.

We had to add one line to configure the ASA to route to the ISP .

Open an SSH client and connect to your ASA's IP.
Type enable
Type config t
Type interface vlan 2 (or whatever vlan your outside interface is in)
Type ip address dhcp setroute
Type exit
Type exit
Type wr mem

Once applying this, I was able to then get to the internet.

At the time of writing my ASA was running 8.2(1) and ASDM 6.2(1).
