[LARTC] Source Mac based Routing

[LARTC] Source Mac based Routing

[Deepak singhal]

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

Yes. The ip routing tables also allow rule-selection based on fwmarks. This
gives you all the power of netfilter for routing-rule-selection. So, given
something like
iptables -A INPUT -m mac --mac-source ab:cd:ef:01:23:45 -m mark --mark 45
ip rule add fwmark 45 table 45

Would let all packets coming from MAC ab:cd:ef:01:23:45 be routed according
to the rules in routing table 45.
