Hei all,
so we have a little problem: I have a machine with 4 network cards and a ip from the same subnet on every card. (Dont ask me, why we have 4 cards for it ;-) Ok, here's my setup:
----- cut ----- IP=/usr/sbin/ip ROUTE=/sbin/route
ROUTER="192.168.0.102" IP0=192.168.0.200 IP1=192.168.0.201 IP2=192.168.0.202 IP3=192.168.0.203 NM="192.168.0.0/24"
# set up interfaces $IP addr add $IP0 dev eth0 $IP addr add $IP1 dev eth1 $IP addr add $IP2 dev eth2 $IP addr add $IP3 dev eth3 $IP link set eth0 up $IP link set eth1 up $IP link set eth2 up $IP link set eth3 up
# add rules $IP rule add from $IP0/32 pref 100 table 10 $IP rule add from $IP1/32 pref 200 table 20 $IP rule add from $IP2/32 pref 300 table 30 $IP rule add from $IP3/32 pref 400 table 40 $ROUTE add -host $ROUTER dev eth0
# set routing tables $IP route add $NM dev eth0 table 10 $IP route add default via $ROUTER table 10 $IP route add $NM dev eth1 table 20 $IP route add default via $ROUTER table 20 $IP route add $NM dev eth2 table 30 $IP route add default via $ROUTER table 30 $IP route add $NM dev eth3 table 40 $IP route add default via $ROUTER table 40 $ROUTE add default gw $ROUTER ----- cut -----
Now i have the following problem: All UDP packages are created with the right ip, but routed trough the first network card.
Here's a tcpdump (sending a nameserver request to the second ip ...) $ host 192.168.0.1 192.168.0.201
# tcpdump -p -i eth1: 18:13:59.988575 192.168.0.15.1128 > 192.168.0.201.domain: 34740+ (28) 18:14:00.036535 192.168.0.15.1128 > 192.168.0.201.domain: 34741+ (28)
# tcpdump -p -i eth0: 18:14:09.514938 192.168.0.201.domain > 192.168.0.15.1128: 16413 1/3/3 (161) 18:14:09.570556 192.168.0.201.domain > 192.168.0.15.1128: 16414 0/1/0 (81)
Why is the kernel sending this packages trough the first interface and how can i change it to using the right interface?
Regards
