Hi , Has anybody out there implemented source mac based routing .. The Howto mentions the following line : Do routing based on user id (yes!), MAC address, source IP address, port, type of service, time of day or content But i could not find any mention of mac based routing anywhere else .I am also interested in user id based routing ..How to implement these ..I read the man pages for ip rule ..but it accepts only an ip address in 'from' field. Can anybody help on this ? Thanxs Deepak
