[OpenSIPS-Users] Checksum incorrect maybe caused by "UDP" checksum offload

[Ghaith.ALKAYYEM at telecom-bretagne.eu]

Hello,

Could anybody tell me what is the problem with such a configuration:


-------------------         ----------------------------------------    
       --------------------
(UAC)192.168.10.1 |=======> |192.168.10.10 [OpenSIPS]  
192.168.20.20|=======> |(UAC)192.168.20.1 |
-------------------         ----------------------------------------    
       --------------------


The mysterious point is that all packets orginating from the interface  
(192.168.20.20) towards UAC(192.168.20.1) have Bad checksum in the UDP
level. This happened with/without RTPproxy, so i'm wondering whether I  
should care about this problem or not because the sound is conveyed  
and everything
seems okay.

Regards.
