I have a small offic here with a few workstations and I would like to implement a small server for stuff like a proxy server, samba etc. This is the topology of said network:
+-----+ dynamic +--------+ +-------------------+ +--+workstation1 | | /56 prefix | | | Debian server | +--------+ | ISP +--------------+ Router +-+eth0+-+ +-+eth1+-+ switch +--+workstation2 | | dynamic | | | (squid,dhcp,etc.) | +--------+ +-----+ IPv4 address +--------+ +-------------------+ +--+workstationX
I would like to have the server assign global (maybe local as well) IPv6 addresses and private IPv4 addresses to all devices connected to eth1 via the switch. I have been able to get NAT masquerading working with dnsmasq and iptables but I can't get IPv6 traffic or even distributing IPv6 addresses to work. The router has three different settings in the IPv6 DHCP server tab:
- assign DNS server only
- assign DNS server and IPv6 prefix to downstream routers (what I assume should be enabled)
- assign DNS server, IPv6 prefix to downstream routers and IPv6 address
I tried following this guide. It describes how to set up a DHCPv6 server with dnsmasq. I have a working eth0 which gets a global, unique local and a link local address. But my eth1 interface never gets a global IPv6 address, only a link-local one. The devices behind the server all have a working IPv4 address but I can't set the IP to a static one because the prefix is dynamic and changes every night. Currently I'm stuck at this point.
Here are my configuration files.
Thank you for your help.
