    @jknott said in fe80::1:1 as static route for ipv6 track interface LAN? also LAN link-local no response?:

    There are 256 possible prefixes within that /48. You use the other prefixes for other interfaces.

    My mistake. That should be 65536, not 256. Better have another beer. 😉

    @bob-dig Thank you, but why the German sub-forum? 🤔

    In the end, I will have to try what you suggested. I was hoping to get to know, how to analyse such issues, to learn something and solve future problems by myself.

    Well, your title differs from what you say in the post.

    While it is quite possible to resolve v4 records. i.e. A records which always return ipv4 addresses compared to AAAA records which are ipv6 records, you will never be able to ping ipv4 domains from an ipv6 network.

    These are two completely independent networks.
    A ipv4to6 nat device is needed, (or an ipv4 address) having access to both networks to be able to ping v4
    This is also known as a nat64 device.

    Unfortunately pfsense has this set to a future release, since ipfw is deprecated.

    While there is a cost of moving to IPv6, there is also a cost of not moving. For example if a company like Amazon doesn't support IPv6, it will become more difficult to do business in China. Another major ISP and cell carrier is Bell Canada. They don't provide IPv6 to their ADSL connected customers, but they barely provide it to their cell customers (they fail testipv6.com). This means their networks already support IPv6. A reseller that uses Bell's ADSL service, Teksavvy, manages to provide IPv6 where Bell doesn't. It appears most of the work is already done for Bell to provide IPv6 properly and to all customers. Also, years ago, the U.S. government mandated IPv6 for all public facing servers and not too long ago for all network suppliers. So, more and more, those who do not enable IPv6 look like they have their head in the sand.

    @joe90

    If it is assigning an address from with your prefix, then that address will start with your /56 prefix.

    I don't have any experience with IPv6 on PPPoE or with OpenWRT, so I don't know what else to check.

    However, you don't need a WAN GUA. If you want to access pfSense from elsewhere, you can use the LAN interface address.

    @aeminkocal

    Is the VM set up as a bridge or NAT connection? If NAT, the IPv4 address will be in a different subnet than the LAN and IPv6 won't work. You need to bridge the interface. Also, it might help to mention which VM you're using.

    After I reset pfSense, and did a new setup, the issue still remain. I can't connect to archlinux.org via IPv6.

    @johnpoz said in Not able to connect to some website:

    I would suggest he moves his lan back to 1500, and then get with his ISP for the proper setup for his wan connection.. A common pppoe mss clamp size is like 1452.. But for optimal working with his ISP he should contact them for proper setup.

    I agree, I should consult my ISP for help. I left MTU and MSS default. Will it related to PMTUD no working? The last result might be using pfSense in transparent mode. I've never tested it yet.

    Another issue is ICMP req always failed (tested using ipv6-test.com), even I allow it on WAN interface. This didn't happen on my last configuration, which is pretty much the same as this one except I left DHPCv6 enable. I think I disable DHCPv6 last time, MyPC use RDNSS instead. I'm scratching my head off.

    I just now found a small config in the bridge advanced setting:
    Screenshot from 2022-05-17 21-33-59.png
    My local hosts now have an autoconfigured ip in the LAN-range (At least, I assume it's auto-configured, since the dhcp6 server isn't working still)
    Routing is still all broken though, so it's only a small boon (And probably isn't helping the hosts in question at all, having to realize ipv6 isn't an option after timeout)
    Still - Wanted to keep you guys posted, if this could trigger something

    @johnpoz said in IPv6 can not connect to IPv6:

    I vpn into my pfsense over their translation setup just fine.. Not saying that couldn't be an issue..

    NAT breaks IPSec authentication headers. Other VPNs, such as OpenVPN use plain UDP that passes through NAT. Also, WiFi calling uses IPSec in UDP for the same reason.

    @jknott The USB-stick in the default mode is firewalling the traffic, preventing me from listening for connections. The built-in web-UI also doesn't have any option, whatsoever, for port-forwarding.

    As for PPP, yeah, it's old. NCM-mode would be faster, but it's apparently not supported by pfSense.

    @georgemv

    You set a unique prefix ID for each interface. You do this in theIPv6 Prefix ID box. With a /56, your choices range 0 - ff.
