I am learning new things all the time and the latest is the ASA5505. While much of it is simmilar to me because of the PIX experience I have had I am feeling lost with how to set up PAT while leveraging the current internet connectivity I have. That said I have FiOS using a Verizon router/firewall/WAP UltraLine Series 3 and the trouble I am facing is how to point my outside interface to enable dhcp. Please know that I have looked at so much on line material and nothing is really helping - seems most of what I read is puked up from some manual someone mentally digested and does little to help me realize what must be done to make it work.
Below is my current config (not that it is complete):
This post (
) does a phenomenal job walking you through the process of setting up the ASA 5505 with PAT and Internet connectivity. I've used it about four times already and I'm successful every time with it.
I recommend clearing startup-config on your ASA and starting over when you go through that thread. If you're still unsuccessful, let us know and I can cross compare your running-config with mine. I'm not an ASA expert either, so I can't do that right now .

I understand that you want the outside interface to get an IP from a remote/outside DHCP server. Am I right?
If so, I can't seam to find a problem in your config. The line ip address dhcp should have done it. I even copy pasted your config into a fresh ASA and the outside got an IP from my DHCP server immediately!!. As shown:
ciscoasa#show interface vlan 2
Interface Vlan2 "outside", is up, line protocol is up
Hardware is EtherSVI
MAC address 001d.451c.1b23, MTU 1500 IP address 192.168.0.162, subnet mask 255.255.255.0
Traffic Statistics for "outside":
Try to remove and add ip address dhcp again. Are you sure also that there is no firewall on the DHCP server or in between the ASA and the DHCP server?
r0nni3's post above is an excellent one for starters. I've previously recommended it to the fw.cx team and Chris liked it. So I second KiLLaBeE on having a look at it H4RR1S0N
