Hi,

Im having problem deploying containers with different subnets
while the NH has only 1 NIC connected to a swich with 2 ot more subnets. I tried both with or without VLANS on the switch.
The setup is as follow:

NH - 1 nic main IP 62.90.150.20/26
All VM's that get IPs from this subnect works ok
But when i add a VM with IP from the other subnet for example 62.90.160.5 wich is on 62.90.160.0/24 (but on the same switch
it doesnt work even after running

route add -net 62.90.160.0/24 dev eth0

on NH.

The 2 subnets connected to the same switch but have different gateways, both on the same firewall but on different ports.

Is this setup possible?

I tried to setup this setup with veth and it works but i rather not work with veth due to strange network issues and breaks on the host everytime the VM start(about 30 seconds network outgage)

Any suggestunes would be great.

Ronald,
