I have a host with two interfaces eth0 and eth1
eth0 has a local ip
eth1 has no ip
Since Proxmox 2.0 I recieve this message:

eth1 received packet with own address as source address

Why do I get this message?

My interfaces:
# network interface settings
auto lo
iface lo inet loopback

iface eth0 inet manual

iface eth1 inet manual

auto vmbr0
iface vmbr0 inet static
address 192.168.1.1
netmask 255.255.255.0
gateway 192.168.1.2
bridge_ports eth0
bridge_stp off
bridge_fd 0

auto vmbr1
iface vmbr1 inet manual
bridge_ports eth1
bridge_stp off
bridge_fd 0

Seems there is some kind of loop. Does it help if you set "bridge_stp on"?

Hello Dietmar,

Changed the setting to "on" and the error still occurs...
Strange thing is eth1 doesn't have an ip address, or is it the ip6 address that sends the packet?

Can you show your ifconfig result ? And 'ip r' would be great.

Hello Nemesiz,

Here's the ifconfig:

And here the "ip r":

192.168.1.0/24 dev vmbr0 proto kernel scope link src 192.168.1.3
default via 192.168.1.5 dev vmbr0


For your information:
eth0 and eth1 are on a seperate network (also physically).

Hard to suggest something. Try to check MAC address inside 102 VM.
Click to expand...


VM102 is pfSense v2.0.1 64-Bit

VM em0 MAC: 02:AA:30:84:F4:52 (vmbr0)
VM em1 MAC: 0A:84:5E:B2:A6:A1 (vmbr1)

Hmm, shouldn't these be the same as the MAC addresses in tap102i0 and tap102i1?

Inside and outside VM MAC has to be different. I believe your Internet comes from eth1 and with help of pfSence you masquerade it to others VPS. I do what way too. But i don't have any problem.

Exactly eth1 is the WAN side and eth0 is the LAN side.
Do you use v2.0 of Proxmox, because with v1.9 I did not have this message.
I don't have any problems, everything is working like it should, I only get the message.
