Re: routing problem

ok example

ethrnet ip / gateway 87.224.234.XX / 87.224.234.1(metric 10)

pppoe exaple ip(every reconnect are ifferent ip and gateways) = 212.122.43.12 / 212.122.43.6(metric 1)

i want allow users be available to work with 87.224.234.XX .

similar proble with two ethernet cards. which can be resolved with


ip route add gateway1 dev eth1 table ETH1
ip route add default via gateway1 dev eth1 table ETH1
ip route add gateway2 dev eth3 table ETH3
ip route add default via gateway2 dev eth3 table ETH3

iptables -t mangle -A OUTPUT -m owner --uid-owner 108 -j MARK --set-mark 1

ip rule add fwmark 1 pri 100 table ETH3

iptables -t nat -A POSTROUTING -o eth3 -j SNAT --to-source=gateway1

echo 0 > /proc/sys/net/ipv4/conf/eth3/rp_filter

ip rule add from ip1 pri 200 table ETH1
ip rule add from ip2 pri 300 table ETH3

but for this method i must know gateway of any device. but it is different every connect pppoe :(
i hope you will understand whaat i mean. :)

Thanks.

I think you might wan to change the IP scheme, I suppose now both interfaces are on the same subnet, u might need to put them on different subnets hence two gateways.
 
please keep us posted

nono :)

i have 2 default routers now in debian etch.
0.0.0.0

pppoe metric is upper than ethernet

when i receive packet via ethrnet response packet my server send via pppoe.
I need to response via ethrenet :)
and when i receive by pppoe i need t oresponse via pppoe.

Thanks.

Alexandr,
 
I am not sure exactly what you mean
 
but if the problem is that it is assigned different ip everytime and you are using static routes on other devices you can link the mac address of this machine to a specific ip address on the dhcp sever so it will  take the same ip everytime.
 
Regards,
Sami
