I think there is an error in your firewall.<br>
You have "removed all rules for testing", but the policy is set to
DROP.<br>
<pre class="bz_comment_text"># ip6tables -L -v -n -x
Chain INPUT (policy DROP 211 packets, 57041 bytes)
pkts bytes target prot opt in out source destination </pre>
<br>
This means that ALL traffic will be dropped.<br>
<br>
You need to do "ip6tables -P INPUT ACCEPT" and test again.<br>

<br>
We run fedora 34 on our boxes.
<br>
Dhclient stopped receiving responses from dhcp-server.
<br>
Dhclient only logs XMT steps.
<br>
This happens even with the (ipv6) firewall disabled.
<br>
Tcpdump shows the responses arriving.
<br>
Because of this I created bug

<br>
How can I investigate this issue further and fix it?
<br>

Kind regards,
