Configure PIX 506E from using multiple static IPs to single static IP
Posted on 2007-10-11
Our PIX 506E is currently configured to NAT using a range of static IPs provided by our ISP. I have one static route for our Exchange server. As I now understand it I should be able to NAT the LAN through a single static IP, but I confess I'm someone who has learned this stuff from the middle out and whose eyes often glaze over when trying to get the fundamentals (i.e. reading the Command Reference). Basically, what I'm trying to avoid is using PAT because the Cisco documentation warned that it would break certain media protocols and we deal heavily in the creation of various media file types. So using NAT exclusively seemed the safest way to go.
So, this is one you folks can answer blindfolded, I'm sure. Help and enlightenment is appreciated.
Here's the current relevant statements from the config. Thanks.
global (outside) 1 xx.yyy.zzz.41-xx.yyy.zzz.62 netmask 255.255.255.224
nat (inside) 1 0.0.0.0 0.0.0.0 0 0
static (inside,outside) xx.yyy.zzz.35 192.168.16.5 netmask 255.255.255.255 0 0
