How to get IPv6 IP address from ISP router for all devices instead of pfSense ?



  • My current setup is :

    ISP–------------------>ISP Router------------------------------>pfSense Router------------------------------------->All Devices

    IPv4 works the way it should. But IPv6 doesn't work at all. The pfSense router is getting an IPv6 address from ISP router (which is at my home) but none of the LAN interface devices are getting IPv6 address.

    So I was thinking if there is a way to completely omit pfSense IPv6 DHCP and make the ISP router hand over the IPv6 addresses to all devices instead.



  • Why not just put the ISP router into bridge mode?  That's what I have here.



  • The ISP Router has very limited configuration. Bridge mode is not available.

    Have you asked them?  They might have to do it for you.



  • You need to delegate IPv6 from your ISP-Router and pfsense has to ask of it. Is your ISP-Router able to delegate ?

  • Nope it is not able to delegate. It is a very crappy router with almost no options to configure.



  • Have you asked your provider for a bridge mode? A lot of ISPs, like my own need to do it internal. Probably the best for most as it might cause confusion.



  • Most providers' gateway devices have some way to enable bridge mode… some will have it buried in an advanced option, others you may need to call and have them enable it instead... but this is what you want so you don't have pfSense sitting behind another router with its own firewall and security settings. With their device in bridge mode, your pfSense box should be able to request an IPv6 address for WAN and a prefix for LAN. If you have multiple internal networks that you want IPv6 addresses for, you'll need to get a smaller prefix that gives you multiple /64's for your own use.

    I had the exact same issue. Sold my Fritzbox which wasn't able to act as a bridge and bought a decent VDSL Modem (Draytek Vigor 130). Working like a charm now.
