Hi,
 
I have established two connections to the same ISP. After that ip route list
showed this:
 
195.14.247.94 dev ppp0  proto kernel  scope link  src 81.173.141.207
195.14.247.94 dev ppp1  proto kernel  scope link  src 81.173.237.84
192.168.0.0/24 dev eth0  proto kernel  scope link  src 192.168.0.1
default via 195.14.247.94 dev ppp0

I want 192.168.0.2 to connect to the internet by ppp1 and all other
computers to connect by ppp0. So I entered following commands in the shell:
 
echo "1" > /proc/sys/net/ipv4/ip_forward
iptables --table filter --policy FORWARD ACCEPT
 
iptables --table mangle --append PREROUTING -s 192.168.0.2 --jump MARK
--set-mark 4
ip rule add fwmark 4 table 4
 
Then I modified the main table and table 4, so that they looked like this:
 
Server:~# ip route list
195.14.247.94 dev ppp0  proto kernel  scope link  src 81.173.141.207
192.168.0.0/24 dev eth0  proto kernel  scope link  src 192.168.0.1
default via 195.14.247.94 dev ppp0

Server:~# ip route list table 4
195.14.247.94 dev ppp1  proto kernel  scope link  src 81.173.237.84
192.168.0.0/24 dev eth0  proto kernel  scope link  src 192.168.0.1
default via 195.14.247.94 dev ppp1
 
an entered ip route flush cache in the shell.
 
But after this, 192.168.0.2 could not connect to the internet anymore.
 
What is wrong with my routing tables?
 
Thanks,
 
Ole
