Cisco documents for linux administrators

Hello all, I need to configure a Cisco ASA 5510 as a router.

My current knowledge is more linux/iptables administration, and I am a little bit lost by the Gui interface of the cisco.

For instance, I want to create a NAT to redirect web traffic to two servers :

88.191.xxx.xxx / \ / \ www www 192.168.1.2 192.168.1.3

If I know how to do this using iptables on Linux, I am looking for a tutorial on Cisco servers for cisco newbies like me.

On linux, we have Source NAT and Destionation NAT, and on Cisco, I found Static NAT and dynamic NAT...

I also say that I prefer to use the CLI.

So, can you give me some URL where I'll be able to find some informations to configure my network.

Thanks.
