It depends how you want the PIX to "listen" on the IPs.  You can only assign
one IP address to the external interface, but you can have the PIX "listen"
on other IP address and statically translate them or map them to an internal
device such as a server.  For instance:

**Set the outside IP**
ip address outside 192.168.100.1 255.255.255.240

**Set up static translations for the PIX to "listen" on other IPs**
The first entry tells the PIX to "listen" on 192.168.100.2 and when it
receives data on that IP, translate and send the data to the internal IP of
10.0.10.25
The same goes for the second entry only listening on 192.168.100.3
static (inside,outside) 192.168.100.2 10.0.10.25 netmask 255.255.255.255 0 0
static (inside,outside) 192.168.100.3 10.0.10.25 netmask 255.255.255.255 0 0

Hope this helps!

Aha, obvious when you think about it - many thanks Aaron, I think this
is exactly what I needed

Thanks again, Adrian
