Hello, I am experiencing a network malfunction with the OVS configuration I developed for the Debian/Proxmox 5.1 environment.
I have a dedicated server with two network interfaces. The first is intended to give access to the public network. The second is connected on a private network and gives access to a SAN through a vlan. The identifier of this vlan is worth 2001. I configured the Debian file /etc/network/interfaces as follows: auto lo iface lo inet loopback # Public interface auto enp1s0f0 iface enp1s0f0 inet static address 12.34.56.78 netmask 255.255.255.0 gateway 12.34.56.1 broadcast 12.34.56.255 network 12.34.56.0 dns-nameservers 12.34.56.1 dns-search example.com # Private bridge auto vmbr1 allow-ovs vmbr1 iface vmbr1 inet manual ovs_type OVSBridge ovs_ports enp1s0f1 vlan2001 up ip link set vmbr1 up mtu 9000 # Layer-2 Port allow-vmbr1 enp1s0f1 iface enp1s0f1 inet manual ovs_bridge vmbr1 ovs_type OVSPort pre-up ip link set dev enp1s0f1 mtu 9000 up ip link set enp1s0f1 up # Private Layer-3 interface allow-vmbr1 vlan2001 iface vlan2001 inet static ovs_bridge vmbr1 ovs_type OVSIntPort ovs_options tag=2001 ovs_extra set interface ${IFACE} external-ids:iface-id=$(hostname -s)-${IFACE}-vif address 10.20.30.100 netmask 255.255.255.240 mtu 9000 post-up ip route add 10.30.0.0/24 via 10.20.30.254 This configuration works well. A need having evolved, I am forced to create a bridge on the public network. So I adapted the previous configuration as follows: auto lo iface lo inet loopback # Public bridge auto vmbr0 allow-ovs vmbr0 iface vmbr0 inet manual ovs_type OVSBridge ovs_ports enp1s0f0 veth0 up ip link set vmbr0 up # Layer-2 Port allow-vmbr0 enp1s0f0 iface enp1s0f0 inet manual ovs_bridge vmbr0 ovs_type OVSPort up ip link set enp1s0f0 up # Private Layer-3 interface allow-vmbr0 veth0 iface veth0 inet static ovs_bridge vmbr0 ovs_type OVSIntPort ovs_extra set interface ${IFACE} external-ids:iface-id=$(hostname -s)-${IFACE}-vif address 12.34.56.78 netmask 255.255.255.0 gateway 12.34.56.1 broadcast 12.34.56.255 network 12.34.56.0 dns-nameservers 12.34.56.1 dns-search example.com # Private bridge auto vmbr1 allow-ovs vmbr1 iface vmbr1 inet manual ovs_type OVSBridge ovs_ports enp1s0f1 vlan2001 up ip link set vmbr1 up mtu 9000 # Layer-2 Port allow-vmbr1 enp1s0f1 iface enp1s0f1 inet manual ovs_bridge vmbr1 ovs_type OVSPort pre-up ip link set dev enp1s0f1 mtu 9000 up ip link set enp1s0f1 up # Private Layer-3 interface allow-vmbr1 vlan2001 iface vlan2001 inet static ovs_bridge vmbr1 ovs_type OVSIntPort ovs_options tag=2001 ovs_extra set interface ${IFACE} external-ids:iface-id=$(hostname -s)-${IFACE}-vif address 10.20.30.100 netmask 255.255.255.240 mtu 9000 post-up ip route add 10.30.0.0/24 via 10.20.30.254 Since, after reboot, I can not connect to the public interface anymore. Access to the private interface continues to work correctly. I'd like to connect these two bridges with a virtual machine acting as a router/firewall. For now I will like to solve my tcp/ip link problem. I beg to ask you to help me understand my mistake.
