custom router WRT54G firmware

Create custom build of Linksys router WRT54G firmware to add the feature of restricting access to certain websites based on time. The goal is to restrict the time a defined computer (MAC Address) can access a certain website (url). The ultimate goal is to only allow a user to access a certain site for a specified time per day. Once they have accessed the site for the determined time the url will be blocked. Example MAC Address 00:12:17:1D:4F:EE can only connect to a list of IP addresses and or a list of url’s for a defined time per period. Create custom policy Define custom policy with MAC address Define website IP addresses and or url (many gaming sites have multiple IP addresses so need to make provision to deny blocks of IP addresses) Define number of minutes per period Example 120 minutes per 24 hr period Example 420 per 7 days
