i have a isp. and i have ubuntu server 12.4 with three nic.
here eth0 ip is 10.10.10.15 with the gateway 10.10.10.1,
eth1 ip is 10.0.0.20 with the gateway 10.0.0.1
and last eth2 my local lan ip 192.168.20.1.
i want to bridge eth0 and eth1 bandwidth for eth2.
here eth0 have 1mbps from external isp and eth1 have 512 mbps from external isp.
i mean in eth2 i want a gateway with the bw 1500mbps.
i saw some example with bridge utils but i dont understand about gateway of br0, imean like :
iface eth2 inet static
bridge_ports eth0 eth1
i need full bw(1000mbps+512mbps) into one mean (eth0+eth1) -> to eth2(1500mbps) what will my eth2 gateway and how to load balance the bw
