Configuring PIX 515 with Comcast

c515-1> enable
c515-1# conf t

Configure e0 (outside interface) to get DHCP address from Comcast

c515-1(config)# int e0
c515-1(config-if)# ip address dhcp setroute
c515-1(config-if)# no shut

Configure e1 (inside interface) as 10.0.10.1

c515-1(config-if)# int e1
c515-1(config-if)# ip address  10.0.10.1 255.255.255.0

Configure NAT (Perform NAT on all addresses in the 10.0.10.x subnet)

c515-1(config)# nat (inside) 1 10.0.10.0 255.255.255.0

Configure Global Address

c515-1(config)# global (outside) 1 interface

I still have a(n extremely) basic config, e0 is the interface connected to my cable modem which is receiving it’s IP address via DHCP from Comcast. My internal interface is e1 which is statically set to 10.0.10.1. Next I need to get DHCP configured on the 515, put my current wireless solution (Apple Airport Extreme) into bridge mode and eventually have it be replaced by a Cisco AP. I’ll also be adding different vlans into my network for separating some things out but for now I wanted to make blog posts on the individual steps.
