Linksys EtherFast® Cable/DSL Router with 4-Port Switch BEFSR41 - this is the router I have. Under the Advanced Setup there is Dynamic Routing. It gives me an option between Gateway or Router. Default is Gateway. First off, whats the difference between the two? Is setting it up as a Router more secure? If so, how do I go bout it? Ive been trying to find sites which help you set up Routers and I have no luck. Please if anyone can help it would be great!
