[Bug 92] New: ICMP type 3 code 4 message generation - incorrect address generation on some NATed connections
https://bugzilla.netfilter.org/cgi-bin/bugzilla/show_bug.cgi?id=92 Summary: ICMP type 3 code 4 message generation - incorrect address generation on some NATed connections Product: netfilter/iptables Version: linux-2.4.x Platform: i386 OS/Version: RedHat Linux Status: NEW Severity: normal Priority: P2 Component: unknown AssignedTo: laforge@netfilter.org ReportedBy: jeff@folts.com CC: netfilter-buglog@lists.netfilter.org On an SNAT (and maybe DNAT as well) connection, any path mtu discovery messages (icmp type=3 code=4) generated from traffic going from the destination back to the source need to set the DST address in the payload of the pmtud message to the translated address instead of the orginal address. The recipient of the pmtud message needs to see the translated address instead of the pre-translated original address to be able to associate the pmtud message with the connection. ------- You are receiving this mail because: ------- You are on the CC list for the bug, or are watching someone who is.
