What makes you think that this is caused by the DHCP server? Can you
give us the output of your "netstat" command? Is the dhcpd service
listening to an IPv6 address? Maybe a "ps -ef | grep dhcpd" will give us
Try disabling IPv6 by adding "ipv6.disable=1" on the
GRUB_CMDLINE_LINUX_DEFAULT variable in the /etc/default/grub file, then
run "update-grub" and reboot. But there's little chance that the DHCP
server has anything to do with your problem because it is not dual-stack
: it can operate only for one protocol at the time (DHCPv4 *or* DHCPv6).
Have a nice day,
