I think this would be much easier and straight-forward if I introduced a router into the equation, but I might need some help with this on my ASA5505 connected directly to a cable modem (and performing basic gateway/NAT functions at home). Does anyone have any information on how to configure this directly on the ASA5505?
Sorry if this was already covered elsewhere -- I've searched around these forums and the internet for some ASA specific information, but everyone else seems to have the ASA behind a router.
This is my ASA sho ver output (in case this just isn't possible for me):
