I have multihome network line. I want to use multi gateway, but i have some trouble +-----------------------+ | 30.1.1.1 (eth0) | <----> 10.1.1.1 ( eth1) < ---> internet | | | 10.1.1.2 (eth1) | | | <----> 20.1.1.1 (eth2) < ---> internet | 20.1.1.2 (eth2) | +------------------------+ eth1 ip : 10.1.1.2 gw ip (eth1) : 10.1.1.1 eth2 ip : 20.1.1.2 gw ip (eth2) : 20.1.1.1 ip route add default dev 10.1.1.1 dev eth1 table 1 ip route add default dev 20.1.1.1 dev eth2 table 2 ip rule add fwmark 0x01 table 1 prio 200 ip rule add fwmark 0x02 table 2 prio 255 iptables -t mangle -A OUTPUT -i eth1 -d 192.168.0.0/24 -t mangle -p tcp --dport ftp -j MARK --set-mark 1 iptables -t mangle -A OUTPUT -i eth2 -d 192.168.2.0/24 -t mangle -p tcp --dport ftp -j MARK --set-mark 1 if i try to connecting to 192.168.0.1, machine use line 1 ( eth1) if i try to connecting to 192.168.2.1, machine use line 2( eth2) Although Machine use gw2, machine source ip address is eth1 ip address. Can I use eth2 ip address when Machine use gw2 ? I can not use "iptables SNAT" in OUTPUT Chain. I want just like this command "iptables -t nat -A OUTPUT -o eth1 --to 10.1.1.2 -j SNAT" but i can't use this command. Thanks for reading my articles
