Hi, I do a project in networking. The subject is "multipath in ipv6". For this I need to create different routing tables in ipv6 and add to each different routes (different next hop) for the same destination to it. For the implementation I have the following problem. My scenario for testing is. I have two routes to a destination D. When I send a SSH packet, I do it via node B (fec0::B) and for a HTTP packet I do it via node C (fec0::C). Node B and C are not connected together. When I do: for SSH # ip6tables -A PREROUTING -t mangle -i eth1 -p tcp --dport 22 -j MARK --set-mark 1 # echo 201 ssh.out >> /etc/iproute2/rt_tables # ip rule add fwmark 1 table ssh.out # ip -6 route add default via fec0::B dev eth1 table ssh.out for HTTP # ip6tables -A PREROUTING -t mangle -i eth1 -p tcp --dport 80 -j MARK --set-mark 2 # echo 202 http.out >> /etc/iproute2/rt_tables # ip rule add fwmark 2 table http.out # ip -6 route add default via fec0::C dev eth1 table http.out then: # ip -6 route show table all it shows me the added route, but without "table ssh.out" at the end of line as it do when we operated in ipv4. This means it ignores the last two arguments (table ssh.out or table http.out) when we add a route to the table ssh.out (or http.out) and therefore these tables remain empty. When it has a packet to send it does not know to which next hop it has to send. So, the marking packets is here useless. Do I have to load explicitly some modules for netfilter ipv6? How do I have to configure the config files or the kernel? I achieved multipath in ipv4 (ip rule, ip route...) without bigger problems. I use Kernel 2.6.8 and Mandrake 10.0/1. ____________________________________________________ Start your day with Yahoo! - make it your home page http://www.yahoo.com/r/hs
