Hi,

I have = established=20 two connections to the same ISP. After that ip route list showed=20 this:

195.14.247.94 dev=20 ppp0 proto kernel scope link src=20 81.173.141.207
195.14.247.94 dev ppp1 proto kernel scope=20 link src 81.173.237.84
192.168.0.0/24 dev eth0 proto = kernel =20 scope link src 192.168.0.1
default via 195.14.247.94 dev=20 ppp0

I want = 192.168.0.2=20 to connect to the internet by ppp1 and all other computers to = connect=20 by ppp0. So I entered following commands in the = shell:

echo "1" >=20 /proc/sys/net/ipv4/ip_forward
iptables --table filter --policy = FORWARD=20 ACCEPT

iptables=20 --table mangle --append PREROUTING -s 192.168.0.2 --jump MARK --set-mark = 4

ip rule add=20 fwmark 4 table 4

Then I modified the main table and table 4, so that they looked = like=20 this:

Server:~# ip=20 route list
195.14.247.94 dev ppp0 proto kernel scope = link =20 src 81.173.141.207
192.168.0.0/24 dev eth0 proto kernel = scope=20 link src 192.168.0.1
default via 195.14.247.94 dev=20 ppp0

Server:~# ip route list table=20 4

195.14.247.94=20 dev ppp1 proto kernel scope link src=20 81.173.237.84
192.168.0.0/24 dev eth0 proto kernel scope=20 link src 192.168.0.1
default via 195.14.247.94 dev=20 ppp1

an entered ip=20 route flush cache in the shell.

But after=20 this, 192.168.0.2 could not connect to the internet=20 anymore.

What is wrong=20 with my routing tables?

Thanks,

Ole
