[Bug 48] conntrack breaks udp path mtu discovery
https://bugzilla.netfilter.org/cgi-bin/bugzilla/show_bug.cgi?id=48
------- Additional Comments From tatonet@tiscali.it 2004-02-25 15:05 -------
I know that this is an old bug report, but it's still opened...
If we save the size of each single fragment we have to face another problem:
how should we re-fragment the packet if original fragments were partially or
totally overlapped?
