I tried and I tried...it's my ISP that's keeping me in the dark,,,their static IPv6 on the Fast5688w doesn't appear to allow pfSense LAN to communicate with WAN so RA cannot give out ULA's...

@mauropc ???? DHCPv6-PD is the normal way for ISPs to provide IPv6 to home users. You get an IPv6 address for your WAN interface and a prefix with at a minimum 18.4 billion, billion addresses and probably a lot more. Maybe you can describe what you're trying to do and problems you're having.

@Gertjan Yeah i clicked submit then noticed my screenshot error (took it while testing) and then had a server issue at work so had to stop "playing". Thats really helpful info and gives me something to work on, i'm a simple man of PPPoE so this is a new config type for me so it's all weird and wonderful.

I occurred to me that I might have some weird config since I was importing config from a chain of older routers so who knows what might have been lurking in that XML. So I did a factory reset on the 6100 and only set the needed things. Same problem. At this point, if someone had a procedure to downgrade the 6100 to 22.5, I would absolutely do that right now.

@catonic said in 2.4.4 ICMPv6 Firewall Rules?: because ICMPv6 is not an option on the drop-down Sure it is.. What do you think ICMP is when you select IPv6? [image: 1695465961105-icmpv6.jpg] Here created a test rule [23.05.1-RELEASE][admin@sg4860.local.lan]/root: cat /tmp/rules.debug | grep "test icmpv6" pass in quick on $TEST inet6 proto ipv6-icmp from any to any ridentifier 1695465595 keep state label "USER_RULE: test icmpv6" label "id:1695465595" [23.05.1-RELEASE][admin@sg4860.local.lan]/root This thread is 3 some years old - if you are having a problem, it would be best if you actually give details of what your trying to accomplish, how and what you have done to test it.

Just to close this out... To avoid any issues at the next upgrade I backed out the two changes in the patch and uninstalled the dhcpleases6 package. Then I added a new gateway on my external router that points to the hyper-v router's ipv6 address on its WAN side (the external router's LAN side), and added a static route to direct the delegated prefix subnet to that gateway. This configuration also works to allow IPv6 to work from the internal hyper-v router's LAN side. These two configuration items will be easy to back out at upgrade, assuming the issue is addressed in the next release.

@kiokoman said in HE Tunnelbroker: but the most important thing of all is that they give you a t-shirt if you became a SAGE That's certainly sage advice!

So nobody has any clue on how you can achieve individual interface assignment?

@netgate_etagten said in ipv6 dns opcode: QUERY, status: REFUSED: why dhcp6c needs to reacquire the address. Did you try setting this https://docs.netgate.com/pfsense/en/latest/config/advanced-networking.html#do-not-allow-pd-address-release

@JKnott https://docs.netgate.com/pfsense/en/latest/firewall/ethernet-rules.html#ethernet-layer-2-rules pfSense Plus software versions 23.05 and later include support for rule-based pass/block filtering of packets based on Ethernet (Layer 2) header attributes.

@Gertjan Your usecase is "dynamic-DNS". I wish pfSense would let you do what you did but with the DDNS-Clients onboard. My usecase is a host-alias for firewall rules, which can be private IPs for v4. And it has worked in the past, now it only works partially.

Thanks for all your support guys, but nothing seems to work on my Qotom pfsense box with this release. Did a new install with CE2.7 and there it works fine. As soon as I upgrade to 23.05.1 the IPv6 network doesn't get any IP addresses. Therefor will put by Qotom box on the shelf for now and re-use my Dell R320-II for the time being. Looking forward for an improved pfsense release.

@johnpoz Yup, that seems to fix it. NDP Table loads up on webUI after setting my current GUA PD as local-zone. So yeah, an option to always set the PD as local-zone would be nice...

@guardian said in Does anybody use Bell/FibeTV (in Canada) with pfSense: My understanding (but am not 100% sure), is that you are not behind NAT Then they will have to provide multiple IPv4 addresses and I doubt they do.

@Gertjan said in How to diagnose IPv6 delegation issues: Putting the ISP router in 'bridge' mode isn't possible anymore in France. Do those routers provide DHCPv6-PD to the customer? That's what pfSense requires to provide IPv6 to the LAN. I'm on Rogers, in Canada, and if I had a fibre connection, I could completely eliminate all their equipment, other than the optical terminal, and install my own router. As I'm on cable, I have to put their modem in bridge mode. Maybe you can do a capture of what's happening on the pfSense WAN port and post it here.

@johnpoz It has a link local now. I don't know why just reassigning the interfaces in the same exact way changed it, but I'm happy with it as long as its working. bce0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500 description: WAN options=800bb<RXCSUM,TXCSUM,VLAN_MTU,VLAN_HWTAGGING,JUMBO_MTU,VLAN_HWCSUM,LINKSTATE> ether 00:26:b9:8b:fc:4f inet6 fe80::226:b9ff:fe8b:fc4f%bce0 prefixlen 64 scopeid 0x1 inet6 2001:558:6040:52:4d97:8d28:xxxx:xxxx prefixlen 128 inet 73.x.x.x netmask 0xfffffe00 broadcast 255.255.255.255 media: Ethernet autoselect (1000baseT <full-duplex,master>) status: active nd6 options=23<PERFORMNUD,ACCEPT_RTADV,AUTO_LINKLOCAL>
