text: ACL - Access control list.  It is used to limit traffic through the router much in the same way as normal firewall rules.\n\nExample:\naccess-list 100 permit tcp any host 171.16.23.1 eq 80\n\nThis would allow any computer to access a webserver on the computer at IP address 171.16.23.1\n\nThe following Link has alot of good examples.
