Check your output to the command "ip route show table local".
For a connected network, the kernel will select the source IP based on these rules. From memory I think, it is possible to change the "src" parameter to use a different IP, so you can play with that.
Anyway, as a general rule, I don't think having multiple IP addresses on the same subnet is a good practice. I would recommend breaking that into multiple subnets so you won't fall under these edge cases.
Cheers,
Patrick

I know this is more of a networking routing question, just trying to see if you can find a better solution than re-architecturing the network. Although maybe that’s the best approach, since this is a pretty new setup. Maybe it’s better to do it now and not using work-arounds?

Hello guys,

I have rtpengine running on a box with ips like this:

external: 172.10.0.10 (advertise 10.10.10.1)
internal: 172.10.0.11 

Both Ips are on the same network.
When i do rtpengine_manage i set "direction=external direction=internal", and the SDP offer is correct.

The problem I'm having is that when rtp tried to send to the internal network, the OS (i believe) selects the first interface (external) ip 172.10.0.10 to reach the internal network. 
This I suppose is not a great deal, but I would like to separate them and only use the internal for internal proxying.

Help is appreciated!

Thanks!
