1605 ios fw

[cventicinque]

Hello,

I have a 1605 with a version of ios that supports firewalls. I want to set it up so that the only ports that are open are the ones needed for web browsing and e-mail exchanges (I am assuming this is 80, 25 and 110). Is there a book or a website you folks could suggest so that I can learn how to do this?

Thank you, Chris

If you have the IOS Firewall feature set you can look over the following URL that shows how to configure it. http://www.cisco.com/univercd/cc/td/doc/product/core/cis7600/122sx/swcg/fw.htm

If you do not actually have the Firewall feature set you can just configure access control lists (ACL). http://www.cisco.com/warp/public/105/ACLsamples.html
