Generally traffic exiting a LAN is controlled at the router or firewall by setting rules in the configuration files for the router or firewall restricting what IP addresses traffic can be sent to, what devices outbound traffic can be sent from. You can also set rules controlling what outbound ports, protocols, and services will be blocked or allowed. Generally the best way to configure is "deny all and allow by exception" where all traffic is blocked by default and then rules are inserted to allow exceptions for specific traffic. You would also insert settings into the Access Control List.
What is the difference between a router and a firewall?
A router (a piece of hardware) is just a way to move/share a connection with several other computers (i.e. using a router so that all three computers in your house can use the same internet connection) - while a firewall (usually a piece of software) is meant to block unauthorized access (hackers) to your computer/network and help protect you from viruses, spam, etc. ----- Put this way---- With a router (with default settings) in between two or more networks, hosts from any two networks can communicate accross, because router has to entertain them (no security zoning) With a firewall (with default settings) in between two or more networks, hosts from any two networks CANNOT communicate accross, because firewall MUST NOT entertain them (Security Zones) ----BTW Read these lines if you are getting interviewed----- ;)

It does not matter if you are connected through wireless or cable, your router can provide firewall protection for all of its ports on the LAN side.

Your routers firewall protects you whether you use the wireless option or not.
