Help with Cisco 5505 (8.3) Config

Can someone help with a Cisco 5505 (8.3) configuration problem? I have a dynamically assigned IP address from the cable modem ISP and am trying to configure simple internet access for the local hosts. The inside hosts are getting the correct DHCP information but can not communicate outside. I can ping the inside interface but nothing on the outside.

packet-tracer input inside tcp 4444 80 returns "No route to host"

Phase: 1
Result: ALLOW
Implicit Rule
Additional Information:
MAC Access list

input-interface: inside
input-status: up
input-line-status: up
Action: drop
Drop-reason: (no-route) No route to host

I had a similar config running in pre-8.3 days but that was with a static IP, so I'm guessing its a simple config issue but I can't find it.

no route set up, need to add following set up

route outside x.x.x.x

x.x.x.x is the gateway provided by your ISP

The config seems to be god, did you get IP addres from ISP?
did you put 'clear xlate' ?

Best regards,

 >ip address dhcp setroute

This sets the default route automatically, no reason to manually set it.

Enable ICMP inspection instead of using ACLS if you want to use ping to test connectivity:

policy-map global_policy
 class inspection_default
 inspect icmp

no access-group outside_in in interface outside

Check the interface to make sure that you are getting an IP address via DHCP. If connected to a cable modem, shut off the modem and the ASA, wait a good 5 minutes for the modem to clear. Power up the modem, then power up the ASA. Then check to make sure you get an IP address and a default route.
