Configure Proxmox with different IP Class's

[starnetwork]

Hi,
i have machine with Proxmox 1.5 and few pools of IP (numbers here are for example)
first pool:
IP's: 212.180.100.110-212.180.100.116
DNS:
Default Gateway: 212.180.110.108
Subnet Mask: 255.255.255.248
DNS: 80.179.50.100 + 80.179.56.100

Second pool:
82.199.60.86 - 82.199.60.96
Default Gateway: 82.199.60.83
Subnet Mask: 255.255.255.240
DNS: 80.179.50.100 - 80.179.56.100

Proxmox interface configurations:
vmbr0 | yes | eth0 | 212.180.100.110 | 255.255.255.248 | 212.180.110.108

when i create new vps with ip from the first pool, its work good, but when i create vps with ip from the second pool, no Internet connection, and no remove connection to the vps

how i can configure the vps with ip from the second pool ?

Best Regards,

Hi,
do you use two different networks on one NIC?
Try to define a second bridge (vmbr1) with eth0:0.
Or post the content of /etc/network/interfaces

Hi Udo,

I am trying the same with different public ip addresses with different segments.
But I couldn't configure multiple brifge within proxmox gui.
Do I have to make it in the config file /etc/network/interfaces?

Hi,
i have tried to bound two bridges to one device (eth0 and eth0:0) - no chance.
For two bridges you need two nics or vlan-tagging on one nic (eth0.1, eth0.5 for vlan 1 and 5).

But if both networks are on one cable, you should reach both networks with the vm - the host should only get an ip from one net.

Hi, can you send me some sample for my configuration ?

Hi all,

I think I did it .-) I tried it with two Class C networks and with my two public networks as well.

Here my ifconfig:

and the interfaces:

There should be only one 'default' gateway - please remove the other.

 

[mr.x]

Hi Dietmar,

but with two different segments we do need two gateways, or?

There is only one 'default' gateway possible. Why do you want 2 default gateways ?

 

[amueller]

Hi dietmar and starnetwork,

you need more gateways to route different networks on one machine.

Due to circumstances that it is only possible to set one default gateway to a interface you need to modify your routing table with source routing (ip from iproute2 package)

ip rule add from secondnet/xy table net2
ip route add default dev vmbr0 via gwnet2 table net2

Hi Andreas,

thanks for this Link of the wiki.
I will give it a try tonight. Will be back with the results tomorrow.

Hi all,

yesterday night I had no time so I did it today.
My first way with the two bridges is not working.
Its not possible to set two bridges on on interface (eth0).
So I searched the internet for a solution.

Just a short review:
I have two /28 networks

1.1.8.176-191
1.1.10.112-127

I found this: http://forum.proxmox.com/threads/841-Add-IP-of-another-subnet?p=4249&mode=linear#post4249

but I couldn't make it working .-(

Here my config:

cat /etc/network/interfaces
# network interface settings
auto lo
iface lo inet loopback

auto eth0
iface eth0 inet static
address 1.1.10.113
netmask 255.255.255.240
gateway 1.1.10.112

iface eth1 inet manual

auto vmbr0
iface vmbr0 inet static
address 1.1.8.177
netmask 255.255.255.240
bridge_ports none
bridge_stp on
bridge_fd 0

But this is not working.
I can reach the ip of eth0 but not the other ones .-(
May be someone see my error.

i just check post: http://forum.proxmox.com/showthread.php?t=492
not working

Please try to use 'tcpdump' to see whats wrong.
