Here is my situation:
I have a pix 515E currently running with private IPs on both the outside and inside interfaces. I now have to have the outside interface pingable from the Internet and cannot figure out how to do it.
This is what I thought I needed to do:
z.z.z.z is the Internet address of the person who needs to ping my pix
a.a.a.a is the new Internet address I am trying to use on the firewall.
10.0.0.1 is the inside interface
access-list outside_access_in permit icmp z.z.z.z host a.a.a.a
static (inside,outside) a.a.a.a 10.0.0.1 netmask 255.255.255.255 0 0
It does not work.
I was thinking maybe I just need a second ip address on the outside interface, but really have no idea.
