Greetings everyone! I apologize if this question is asked in lay terms, I'm just beginning my CCNA and my company would like me to set up a secure network utilizing a cisco 3845 router.
Simply put, we need some form of firewall. Is this already an included option on the router? Or will we need a seperate appliance? If there is a seperate appliance, can it be purchased as a module for the router?
The documentation says that it supports a stateful cisco IOS firewall. However I cannot find further description about whether "supports" means that it includes the ios firewall, or if it is a feature pack that has to be purchased seperately. I appreciate any help you can give me. Thanks!
As I said, I am still very new, so please be gentle :)
