I have a Ubiquiti UDM SE. It uses dnsmasq for DNS, DHCP, and RAs. I
have external DNS and DHCP servers so I want to send RA packets with
the M and O flags set and the A flag reset, but I can't figure out the
proper configuration to do that. Right now just to get RA working on
the subnets for IPv6 I have the following:
enable-ra
ra-param=*,high,0
domain=mydomain
dhcp-range=2001:470:xxxx::,ra-names,slaac
dhcp-range=2001:470:xxxx:10::,ra-names,slaac
dhcp-range=2001:470:xxxx:20::,ra-names,slaac
dhcp-range=2001:470:xxxx:40::,ra-names,slaac
I'm getting autoconf IPv6 addresses but I'm not seeing any DHCPv6
packets on the external DHCPv6 servers (a pair per subnet).
Sounds like "I want dhcp-proxy for IPv6"
Any ideas how I can get this working?
Start with research if "DHCPv6" has such feature.
With IPv6 if the RAs have the M flag set the client will request an
IP using DHCPv6. Right now the RAs I'm getting from dnsmasq don't
have that flag set so I'm only getting autoconf IPs.
