Well what I would like is to mark each flow in its source with a label
(in the flow label field in the case of IPv6 or in an option field in
case of IPv4) and make all the routing based on its flow. Something like
~ IntServ. So, all the routers in the middle (that will be linux boxes)
will route IP datagrams based on both the IP address and this flow
label. As far as I understand, the fwmarks allows me to mark packets and
make rules based on this mark but just in the same computer (am I
right?). What I would like to do is something like taking other fields
of the IP header into consideration (the flow label) for routing it.
You can do this:
- at input, set fwmark from DSCP/flowlabel/option
- route with src/dst/other and fwmark
The only problem is how you set fwmark.
I think you need a netfilter module that can do this.
Best regards,
Rafael
