[SUMMARY] Problem with MTU

[Dusan Djordjevic <dj.dule@tradal.net>]

Hi,

Thanks for answers. Only usable advice was this one:

mahhy@undertow.ca:

I believe you are reffering to Path MTU Discovery, which I am not very 
familiar with, but check:

/proc/sys/net/ipv4/ip_no_pmtu_disc

but it didn't helped. I think this turns of Path MTU Discovery which I 
actually need so my linux can determine MTU of router.

I do not use iptables or ipcahains at all, which was suggestion of Brian 
Coyle. And D. Stimits <stimits@idcomm.com> suggeste that it is expected 
behavior, but AFAIK it is not. DF bit is set so linux can derermine MTU 
of router (Path MTU Discovery). but it doesn't work very well...
