Hi together,
maybe there is someone out there who is able to support me with the current
issue. I was trying my best to search for answers, but still run into problems.
I have got a debian server with one eth0 attached to it. There are multiple
networks attached to the server:
- Public IP Adress 1 (single public IP for dom0)
- Public IP Adress 2 (single public IP for one virtual domU)
- Internal IP Network 10.10.10.x (internal live network attached to 1..n domU)
- Internal IP Network 10.10.20.x (internal dev network attached to 1..n domU)
The very first question is, how to setup the dom0 so that the system is prepared
to handle all different scenarios)? I would like to run a bridged mode (without
routing).
# Loopback device:
auto lo
iface lo inet loopback
# device: eth0
auto eth0
iface eth0 inet static
address 100.0.0.10
broadcast 100.0.0.255
netmask 255.255.255.0
gateway 100.0.0.1
auto eth0:1
iface eth0:1 inet static
address 10.10.10.5
broadcast 10.10.10.255
netmask 255.255.255.0
auto eth0:2
iface eth0:2 inet static
address 10.10.20.5
broadcast 10.10.20.255
netmask 255.255.255.0
By doing this, at least my system (dom0) is able to handle ip traffic. On other
servers I had another eth1 which I added like this:
# bridge for non-live services
auto br1
iface br1 inet static
bridge_ports eth1
address 10.10.20.129
broadcast 10.10.20.255
netmask 255.255.0.0
bridge_stp off # disable Spanning Tree Protocol
bridge_waitport 0 # no delay before a port becomes available
bridge_fd 0 # no forwarding delay
I do not understand how to setup the /etc/network/interfaces for a multi-IP-domU
with one eth0 by using the bridged mode.
Can anybody share some ideas?
