Hi All, I'd like to gauge people's reaction to the idea of dropping RADVD from the Tomato firmware. What isn't commonly known is that dnsmasq can provide all the functionality of radvd for local prefix announcements and will also act as a dhcpv6 server, with integration into the local DNS service too! Since dnsmasq can perform the necessary IPv6 duties I fail to see why radvd should still be included. I don't thing there's anyway that radvd configuration can be customised from the GUI so I don't think the config can even be tweaked. If you're interested in using dnsmasq for ipv6 service then here are a couple of examples: Disable 'Router Advertisments' in IPv6 section of GUI (disables RADVD) Enter in dnsmasq custom configuration (Advanced->DHCP/DNS) enable-ra - This enables IPv6 router advertising exactly as per RADVD If you want to include some DHCPv6 in this (and hence gain local IPv6 addresses in local DNS) then use something like: dhcp-range=tag:br0,::1,::FFFF,constructor:br0, ra-names, 12h enable-ra The constructor option looks at the existing ipv6 address on your local interfaces and constructs a DHCP range based on the address prefix and the locally defined range :1 -> ::FFFF) The above 2 options are in my router and allow windows boxes to obtain IPv6 addresses via DHCPv6, whilst serving Apple iphones/pads etc via the standard SLAAC algorithm (which since apple don't use privacy extensions still allows a DNS entry to be made) The only downside I've encountered is that logging into syslog gets pretty noisy! I'd be interested in other people's experiences.
