Hi guys im trying to make a port redirecction using
iproute together with iptables mangle option .. but for some strange reason is
not working yet, I know i can do it in a diferent way, but the idea is
using packet marking and redirect the packets with a rule.
I have two computers PC1 and PC2
PC1: 192.168.0.1 this is the one connected to
internet, and this machine make the redirection
PC2: 192.168.0.2 this is the smtp
server
So this is what i do in
PC1:
first i mark all the packets incoming for 25
port with "1":
iptables -t mangle -A PREROUTING -p tcp
--dport 25 -j MARK --set-mark 1
then i create a table called smtp:
echo 200 smtp >>
/etc/iproute2/rt_tables
after that i set PC2 as default via for my smtp
table:
ip route add default via 192.168.0.2 table
smtp
and finally i make the rule for smtp
table
ip rule add fwmak 1 table
smtp
this would have to work, but is not redirecting
nothing...
i can see that is making the packets with 1 using
the command iptables -t mangle -L PREROUTING -v but is not
working, any one can help me?
