I'm very interested in learning Cisco, specifically for small business and for companies with less that 100 users +/-. I would like to learn how to configure the routers for setup/install/troubleshooting - opening/closing ports etc - vpn site-site to site configurations etc. I know there are many different types of Cisco Routers/Firewalls and I'm not sure which one to start with but I figured probably PIX 501 since being a small business consultant this firewall is common in these situations.
I have no time now for classroom training so I would like to know if there are any good books for total beginners with Cisco?
I have 10 years experience with networking and know how to configure any 3rd party router/firewall and have some decent experience with MS ISA 2004.
What would you recommend I should do? Are there any virtual labs I can use that will simulate the PIX? Also what about ASA, should I start with that instead of PIX?
