Need help with config multi uplink and proxmox

[Boecki]

Hi together i have a problem with my interfaces file and proxmox. I use a multiple uplink with 4 cards on my server so a solution for bonding mode is given but with multilink i cant find anyone i configured my multilink like this tutourial: http://wiki.ubuntuusers.de/Multiple_Uplink_Routing
Is anyone here who can help me with the inferfaces file to bring up the virtuall machines to the Internet?
Thanks in advance

i think the easiest solution would be to use a virtualized firewall such as pfsense and setup MultiWAN. That way any VMs can use multi uplink internet without any configuration.

Hi symmcom,

i have never used pfsense and MultiWAN so first i try to search a solution over the interfaces file and the multilink script.
Here are my interfaces and multilink.sh

auto lo
iface lo inet loopback

#Uplink1
auto eth0
iface eth0 inet static

netmask 255.255.255.0
