1605 ios fw

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

Re: 1605 ios fw

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
