Title:
Some ICMPv6 packets rejected due to rule ordering
Status in ufw package in Ubuntu:
New
Bug description:
In the default before6.rules file, the following lines:
# drop INVALID packets (logs these in loglevel medium and higher)
-A ufw6-before-input -m conntrack --ctstate INVALID -j ufw6-logging-deny
-A ufw6-before-input -m conntrack --ctstate INVALID -j DROP
are present before the ICMPv6 rules. The problem is that this also
captures echo replies (but, somehow, allows echo requests) and some
IPv6 routing announcements. If I try to ping ff02::1 to ping all
devices on the local network, I only get a response from my own
device.
Moving those three lines towards the end of the file (after all ICMP
rules and before the COMMIT) fixes the issue.
