I have an isp that delivers an ethernet hand off with a /30 public subnet. They also provide a /28 public block for our use.
/30 => edge router => /28 => firewall => LAN (using 1 to 1 NAT & 1 to many NAT)
Can we use the ASA 5505 as both the edge router and the firewall? Where, /30 => /28 => LAN all happens in the ASA?
