Adding a PIX to a network with an ASA already in place.
Posted on 2009-07-06
Currently we have DSL with 6 usable static IP's (49-54). I'm pretty sure that our Modem has NAT disabled and Our ASA acts as the gateway. Our DSL Modem/Router gets xxx.215.125.49. Our ASA Takes xxx.215.125.50 with a global set as xxx.215.125.51 and a static route from xxx.215.125.52 to our SBS server 192.168.xxx.10.
What I want to do is set up our old PIX firewall for a Dev environment separate from our office network. I want to use one (or both if necessary) of the remaining IPs xxx.215.125.53 and 54 for this and connect it straight to the DSL Modem/Router. I would like the inside network to be 192.168.10.xxx. I will probably have more than one computer connected to the Dev environment so they would have to share the 53 (and/or 54) IP.
It would look something like this:
|------- ASA ------- Switch -------- Office network
DSL Modem/Router ---|
|------- PIX ------- Switch -------- Dev network
Can someone please help me configure the PIX for this. Please include the PIX commands too. Thanks!
