Re: DF bit - Dont Fragment


I had a similar Problem with a tunnel - I solved it by setting the MTU of the interface lower. The PMTU discovery didn't work in my case.

Hi Fraser,

tried that... But that seemed just to disable PMTU Discovery, and not
disbale the 'DF' bit... (After the traffic between myself and the server
via a CIPE tunnel stopped working when the packets got tooo large)
- Or is there a bug in packet fragmentation in the linux kernel?
