The reason why dhcp client reset connection was an ICMP message When the client send a REQUEST, the gateway replied with ICMP code 10 (Host administratively prohibited) Then dhcp server replied with ACK -- It happened because iptables on the server did not allow incoming connections to port 67 of the dhcp server and it responded with an ICMP (Host administratively prohibited). But it seems the requests came to the dhcp server anyway and dhcp server responded with ACK.
I sent only dhcp packets in the dump file but there no ICMP messages were included. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1932291 Title: dhcp client resets IP address every few minutes To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/network-manager/+bug/1932291/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
