2 Nic and 2 Gateways

[pezi]

I am evaluating PROXMOX with two NICs:
Nic 1 - private ip address range
Nic 2 - public ip address range
With the help of SQUID and Nic 2 the outcoming HTML request are routed to the OpenVZ VMs - reverse proxy.

My problem.
Nic 1 with gateway and OpenVZ VM with venet works fine - VM can contact the Internet, but the external Nic 2 is available from extern.

Nic 2 has a gateway, the host is accessible from extern. The OpenVZ VM can not contact the internet.

Nic 1 and Nic 2 with different gateway doesn' t work. The host is accessible from extern, but the OpenVZ VM can not contact the internet.

What is wrong with this configuration?
With best regards
Peter

Hi Peter,
two default gateways don't work (how should the linux know which unknown ip address is routable over which gateway?).
Do you need an ip-address on vmbr1? Normaly it's enough to define vmbr1 without ip-address and the VMs takes one ip-address each.
In this case your pve-host is available only via 192.168.123.210 and your VM with 82.125.165.125, 82.125.165.126, 82.125.165.127... or in the 192.168.123-netrwork if you use vmbr0.
Or you use only the default-gateway on vmbr1 and define only networkroutes for vmbr0 (like "ip route 192.168.100.0/24 via 192.168.123.254")
