Raw socket act not right in lxc‏

Thu Oct 15 06:57:30 UTC 2015

Hello!
I use raw socket to send an ip packet and fill the source ip 5.5.5.5. I use tcpdump to capture it:
 15:01:29.385061 IP 5.5.5.5 > 224.0.0.18: VRRPv4, unknown type (9)
It works well.

But when I setns to a lxc and also send the packet:
15:03:41.724126 IP 10.28.50.198 > 224.0.0.18: VRRPv4, unknown type (9)
The source ip of the packet changed to "10.28.50.198" which is the ip of the interface. Seems like the IP_HDRINCL option not working, but the protocol is working.

Is there any method to make the source ip right?

Forgive my bad english.

Best wishes
