It is unclear what you mean here. NM supports IA_PD for connection sharing, it will use prefixes provided by IA_PD on upstream interface to configure downstream interface. Downstream interface (or more precisely - connection active on downstream interface) has to be configured with ipv6.method=shared. You need to describe what you have configured, what results did you expect and what results you observe before any useful comment can be made. > the default IA_NA option with NM cannot generate the right prefixlen, just > configuring 128 . > Is it separate issue or somehow connected to the previous one? DHCPv6 does not provide address prefix length at all. Every address returned by "IA Address" DHCPv6 option has prefix 128. Again you need to explain what you observe and what exactly does not work or works incorrectly and why you think it is related to address prefix length. > > Best Regards > ------------------ > Mars > > > > > > > > > > > > At 2020-11-27 17:54:26, "Thomas Haller" <[email protected]> wrote: >> On Fri, 2020-11-27 at 09:48 +0800, Mars via networkmanager-list wrote: >>> hi, >>> NM uses nm-dhcp-helper as network configuration script for dhclient >>> as follows , how to confiure dhclient-script file within NM ? >>> >>> /sbin/dhclient -d -q -sf /usr/libexec/nm-dhcp-helper -pf >>> /var/run/dhclient-eth0.pid -lf /var/lib/NetworkManager/dhclient- >>> 5fb06bd0-0bb0-7ffb-45f1-d6edd65f3e03-eth0.lease -cf >>> /var/lib/NetworkManager/dhclient-eth0.conf eth0 >>> Thank you very much for any help you can provide. >> >> >> Hi, >> >> >> You cannot (*).
