Hi, Host A has two interfaces: eth0, tap0. I want that all locally generated traffic from user 1004 goes through tap0. This is what I did: iptables -A OUTPUT -t mangle -m owner --uid-owner 1004 -j MARK --set-mark 2 echo 202 bigmac.out >> /etc/iproute2/rt_tables ip rule add fwmark 2 table bigmac.out ip route add default via 10.0.0.1 dev tap0 table bigmac.out ip route flush cache This results in these problems: - packets from 1004 are send out via tap0 but with source ip of eth0. (seen in tcpdump -n -i tap0) - iptables packetfilter rules have to bet set on eth0 and not on tap0. (if i deny everything on -o eth0 no packet is send out to -o tap0 anymore..) Ideas?
