Package: isc-dhcp-server

Version: 4.3.5-3

Severity: important

Tags: ipv6


Dear Maintainer,


The dhcpv4 server works fine. However, the dhcpv6 server does not respond to
solicits, and therefore will not hand out ipv6 leases.

The server does log the solicits, so it is seeing them.


I confirmed this is a bug in the Debian version by downloading the official
4.3.5 version from ISC, compiling it, and then

running it with exact same config file and command line (except for the
location of the server binary). Clients then

get ipv6 leases.
