Hello all, I have a working IPv4 setup as follows: 1) AVM FritzBox as DSL router 2) Debian / dnsmasq 2.80-1 router, with eth0 being uplink to the FritzBox and eth1.X the client VLANs (1-16) 3) a couple dozen clients in the different VLANs
Now I want to expand this setup to IPv6. The router itself has working IPv6 connectivity, with the FritzBox getting a /56 from the provider and distributing a /62 prefix via IA_PD and an IPv6 address (not in the /62 prefix but in the larger /56) via IA_NA to the router, with dhclient dealing with configuring eth0. An example prefix on eth0 would be 2001:a61:2456:b8fc::/62. I want each VLAN IPv6 range to be set up as <prefix>:VLAN_ID:<DHCPv6 allocation>. How do I express this with dnsmasq? In addition: right now I have "interface=eth0, no-dhcp-interface=eth0" in the configuration so that machines in the FritzBox network can access the DNS resolver part of dnsmasq. Unfortunately, "enable-ra" enables router advertisements on eth0, but not on eth1.X according to the logs! How do I prevent this and have dnsmasq only send RAs / respond to DHCPv6 on VLANs where I explicitly state it? Kind regards Marco
