hi, i've got a asa5505, and as a cisco newbie, i tried to configure this on the asdm...no luck so far...

i can ping out using the asdm feature, but when a pc connects to the asa, it can not get out to internet...
right now, i have a static IP configured for my dsl, but the ultimate goal is to have it connect to our cable modem (which takes a dhcp address) wonder how much diff the config would be?

please see below for my config:

Result of the command: "show run"

You will need to add:
access-list inside_access_in extended permit tcp any any eq 80
access-list inside_access_in extended permit tcp any any eq 443
access-group inside_access_in in interface inside

You can probably remove these:
access-list inside_nat0_outbound extended permit ip inside inside
access-list inside_nat0_outbound extended permit ip inside any
nat (outside) 0 inside

You also dont want anyone on the outside accessing your ASA's http interface, remove this:
route Outside 1

After this, try browsing from the inside.   On the ASA, you can issue a show xlate command at the CLI and you should see the internal IP matched with the external interface IP.
