I presume you set a default route using the setroute option, but this is not available if you use the "ip address [ip_address [mask]]" command. When I try to use the "ip address [ip_address [mask]] pppoe [setroute]" command, I get an error.

But you're not using pppoe on the ASA right?

route outside 0.0.0.0 0.0.0.0

Here's the running config output. I'm not sure if it's entirely correct. I got the next ip address from the Netpoia web page.

Your default route would be to an ip address on the same subnet as your outside interface...xxx.xxx.xxx.74 255.255.255.248.

192.0.2.100 is most likely not correct. What is the address on the netopia?

Okay, I changed it to xxx.xxx.xxx.78, which is its assigned address and still no go.

Well, I did a reset to factory defaults and configured NAT within the address range given to me by the ISP; after a few minutes, it worked, so I guess the problem was in address translation across the interfaces.
