[Bug 48] New: conntrack breaks udp path mtu discovery
https://bugzilla.netfilter.org/cgi-bin/bugzilla/show_bug.cgi?id=48 Summary: conntrack breaks udp path mtu discovery Product: netfilter/iptables Version: linux-2.4.x Platform: All OS/Version: All Status: NEW Severity: normal Priority: P2 Component: connection tracking AssignedTo: laforge@netfilter.org ReportedBy: kaber@trash.net CC: netfilter-buglog@lists.netfilter.org ip_conntrack defrags packets at PRE_ROUTING and LOCAL_OUT and refragments them at POST_ROUTING without careing about IP_DF. packets with IP_DF|IP_MF can be refragmented with a different size, so path mtu discovery is broken. Linux nfs itself sends out packets with IP_DF|IP_MF. ------- You are receiving this mail because: ------- You are on the CC list for the bug, or are watching someone who is.
