I have to setup an ASA 5505 at one of our sites that is getting a new Internet connection that is being delivered as an ethernet connection. They have assigned us two public subnets:
X.X.X.X/30 is the "WAN" IP subnet
Y.Y.Y.Y/28 is for customer use.
I'm already using a private subnet for internal use Z.Z.Z.Z/24
According to the ISP, they want us to use the /30 to connect the ASA to their Internet router and use the /28 for internal addresses. Can I use the /30 address on the external address to PAT my /24 and use individual /30 address for static NAT's for specific servers? I would like to avoid using a DMZ if possible.
