I currently have an Airport Extreme as my home office firewall. In addition to handling IPv4 NAT, my ISP (Comcast) delegates an IPv6 prefix to the Airport, which in turn assigns the delegated prefix to my LAN interface and sends the appropriate route advertisements.
I'd like to replace the Airport with a small Linux firewall - the NUC with a second ethernet interface is looking quite intriguing - but I'm having trouble determining whether the IPv6 behavior can be replicated. My basic questions are:
- Can ISC's DHCPv6 client accept a prefix delegation, or only host IPv6 addresses?
- If the above is true, can the DHCPv6 client assign the received prefix to a different interface? Does the client support "on commit", or is that only supported on the DHCP server?
