I have a IBM server x3200 m3 loaded with Ubuntu 10.04 LTS.

My problem is my network I have a 2 different gateways: one is VPN static and one is DSL dynamic.

The internet runs normally when there is only one eth running but when I run two eth at same time the only eth that is working is only eth0?

How can I make run the two eth at the same time without any conflict. Any suggestions?

route output:

Kernel IP routing table
Destination Gateway Genmask Flags MSS Window irtt Iface
200.0.30.0 0.0.0.0 255.255.255.0 U 0 0 0 eth0
10.42.43.0 0.0.0.0 255.255.255.0 U 0 0 0 usb0
192.168.1.0 0.0.0.0 255.255.255.0 U 0 0 0 eth1
169.254.0.0 0.0.0.0 255.255.0.0 U 0 0 0 eth1
0.0.0.0 192.168.1.1 0.0.0.0 UG 0 0 0 eth0

so how can i make my internet run at same time?

You will need to setup your routing table (linux.die.net/man/8/route). If you give us more details about your network, we can help you. – Javier Rivera Jul 19 '12 at 9:00

Which is the internet nick eth1, eth0 or usb0?. I bet for eth0, but I'm not really sure. – Javier Rivera Jul 20 '12 at 15:30
When you connect to the vpn, it changes your default gateway, that's why you lose internet conectivity. What VPN software are you using? – Eric Carvalho Jul 20 '12 at 16:37
