Ok I just purchased a 5505. I am plugging the ASA directly into my DSL Modem. I have a static IP address 71.
29.95.9 that the router is configured with. The DSL Modem connects through PPPOE connection.
First question: Should I configure the Outside interface of ASA with this IP address of 188.8.131.52? Can the ourside interface have the same IP as the Router?
Second: When i let DHCP configure Outside interface, I get the Outside interface to get a 10.1.1.114, which is really the inside interface of my network. I can ping 184.108.40.206 and the Default gateway also. The last resort of the ASA is 10.1.1.100, which is the LAN address of the DSL Modem.
The problem is I want to have VLAN1 to be on the 10.1.1.0 network and the outside to be on a differnt network.
I also want my onsite DHCP and DNS server to handle requests on the internal network also, thoughts on this?
Currently my default gateway for my internal network is 10.1.1.100
I can post a running config if needed. Any help would be appreciated.
