    Status: Open => Needs information

Didier Barvaux requested more information:
Hello,

Difficult to say without more information. Please answer to the
questions hereafter to try to analyze the problem you encounter.

1/ How do you transmit the ROHC packets between Linux_Ubuntu_router_1 and Linux_Ubuntu_router_2? Do you put the ROHC packets directly in Ethernet frames?
2/ You say that one specific frame is malformed. Has that frame some specific characteristics (sorter, larger, specific pattern...) that could explain that only this frames is affected?
3/ You say that one single byte is altered. Which one? The first one, the last one... ?
4/ Just to be sure: with scapy, do you sent the well-formed frame or the malformed one?
5/ What library version do you use?

Regards,
Didier
