I found ipaudit to be excellent. I deployed one interface on the outside
of the FW with a loopback host ip and the other to a management
interface as not to bypass the pix all together (pix 525). then employed
iptables to block all connections on the outside interface. the box
still listens to the traffic but drops any connection attempts. this way
I get to see all the hack attempts on the outside. note you'll need
either a hub (for the 501) or a switch to span the ports. Cat 2950 does
not work with this app. I used a cat 3500 but 2912 or 2924 will do as
well. cat 2950 puts the interface up/down and the box does not see the
link.
below are the dynamic and static. I had issues as well. the pix 6.2.2
code did not accept the pppoe statement at the end of the command
"ip address outside <ip_address> <mask> pppoe" for me (static). I
believe it to be related to my ISP as I've removed all the vpdn config
entries and I still connect with no issues (go figure). if I remember
correctly I also had an issue with the "setroute" statement and had to
add a default to get it to work. These both worked with an ADSL
connection.
I haven't seen any bugs acknowledged by cisco for the pppoe issues I've
had but we'll see in the new code if it differs.
best of luck.
