<div dir="ltr">Hi,<br><br>I tried to set up multiple veth and default GW for each veth in one container[1] by using docker with following command [2].<br>But I got an error[3]. (When I setup with only one Default GW, it works well. So I think I can not default GW for each veth (eth0, eth1).)<br>
<br>Is this my mis-configuration or lxc's bug?<br>Can anybody figure out the cause of this problem?<br><br>Thank you in advance.<br><br>Kenjiro<br><br>[1]<br> +-----------------+ Default GW<br> | +-------------+ | +-------+<br>
