Cisco PIX 501: Can I place the outside/inside on the same subnet?
Posted on 2006-11-08
I am a complete routing/firewall/Cisco newbie so please bear with me and forgive my lack of knowledge as you read my question! It's in two parts: the "is this possible" part and the "how do I accomplish it" part.
I have a 192.168.1.X/24 network with a gateway of 192.168.1.1. I want to take 10 computers and restrict their access to the network (only allowing HTTP in and out to the gateway). Is it possible to place these 10 PC's behind the PIX 501 and accomplish this? Difficulty: I must keep the IP and subnet of the 10 PC's the same as the rest of the network.
If so, how would I do this? I have already set the IP of my outside and inside interface, created the HTTP rule and disabled DHCP. Now what do I do? Define static routes or something? I'm in over my head at this point in the config.
Thanks for any help you can offer!
