I have 5 statically assigned IP addresses from my ISP and I use a Netopia 3364 DSL modem for PPPoE authentication. This box is able to split out the public IPs to downstream firewalls, routers, etc, but when I connect my ASA 5505 to it and assign it one of the static IPs, I am unable to connect to the Internet. I am, however, able to see the web page for the Netopia and I am able to get the configuration to work with a Linksys router (in fact, 2 of them; each assigned a different public IP). I did not configure PPPoE on the ASA 5505 but simply assigned its outside interface to one of the public IPs, as I did with the Linksys. Any ideas?
