NDP proxy where are you
-
Show your numbers if you like help. Report your WAN address subnet-value and your LAN subnet value… [(f you must), hide the first /48 and show the last /80 part… ]
-
Try using ::2 in the first /64 for your WAN IP address and then use the second /64 for your LAN. Usually when ISPs give you just one large block they assume the first /64 inside it is the WAN.
-
You know if you don't like the way your isp is doing ipv6, you can just get a free tunnel from HE.. You cant get a /48 from them if you want.. I have both a /64 and /48 I use the /64 on my lan and then I use a few of the /64's out of the /48 for my other segments and openvpn clients, etc.
Rock solid works deployment.. They even allow you to setup PTR on your ipv6 addresses if you want, etc. Or even delegate the ipv6 networks to your own nameservers, etc. Does your isp let you do that ;)
And you don't have to worry about your isp giving you a different prefix next week.. When you hit a different dhcp server, etc.

Thank you all

i can t change PTR
i can t do bridge the box
i can use a DMZ , they impose (i try this) :
2a02:8428:ef:7501::/64
gateway :
2a02:8428:ef:7500::2/56for my rules you can see the attachments

You have two router in series, cascading networks. ?
If you want public IPv6 on your pfSense-LAN, then your pfSense-WAN have to request your ISP-box with DHCP6-Client for a prefix&subnet first ?, provided your ISP-box can function as a DHCP6-Server…
IPv6, no pfSense issue forya. Your ISP-box has the /56. Your pfSense is a slave with other LAN subnet-value and local prefix between /57 and /63.
Your pfSense-WAN on mask /56 doesn't look correct. (but /64 or /128).
-
Sounds like your settings are OK. If your LAN IP address can ping the upstream gateway then your local setup is fine, and probably even the routing at your next hop is OK, but it sounds like maybe the routing/rules upstream from you is broken.
A traceroute6 to your WAN and LAN IP addresses both stop at your gateway. I'd normally expect it to work if all that is fine, unless the ISP is filtering the traffic.
If you can ping your gateway and a traceroute from the outside to your LAN subnet is OK, then the routing is probably OK at the ISP end of things.
Sure you used /64 for the prefix on all your interfaces?

@hda -> not sure to anderstand :

Your pfSense-WAN on mask /56 doesn't look correct. (but /64 or /128).
do you suggest to have a ip by the dhcp from box for wan IPv6 pfsense?
i can try -
@hda ->dhcp give me a /128 :
inet6 2a02:8428:ef:7500:c9ca:8e5d:732b:d96b prefixlen 128i try to use : 2a02:8428:ef:7500::10 / 64 for pfsense WAN
2a02:8428:ef:7501::10 /64 for pfsense LAN
default getway : 2a02:8428:ef:7500::1/56
2a02:8428:ef:7501::10 can't ping box (2a02:8428:ef:7500::1)have you an idea?

@pra:
…

...Yes DHCP6, and ask for a prefix /62 to pfSense.
Then try to use Track Interface on your pfSense-LAN.
Put a host-PC on the LAN and see if that PC get response from http://ipv6-test.com/ -

Consider: your ISP-Box supplies on request, you probably can not grab a number you like…
SO, don't do all static, but do DHCP6 from pfSense-WAN to your ISP-Box. Then read reply #19 again...

You may read & understand to request a prefix /62 for pfSense from ISP-box (/56) for the pfSense LAN's. The WAN address mask (/64 or /128) no problem for that, just an intermediair. The LAN's are each with a unique subnet and mask /64.

sorry but i can't configure the box ….

Why are you now trying to divide up a /64? You'll have a horrible time trying to use IPv6 with an allocation narrower than /64 on a LAN unless everything on that network supports address allocation via DHCPv6. Some devices only support SLAAC (such as Android devices, also Windows XP if you still use it and haven't installed a DHCPv6 client). SLAAC requires you to advertise a /64 (and exactly a /64) for things to work correctly.
Are you running router advertisement on your LANs (Services -> DHCPv6 Server/RA, Router Advertisements tab)?
I'd start by working out what your ISP supplied box offers. If it will allow you to delegate prefixes via DHCP-PD, your task becomes a lot easier. You've said you can't bridge this device, but does the ISP allow you to replace it with a DSL bridge and use PPPoE or similar?

I have a similar issue where NDP proxy would be really useful.
My colo provider gives me a /64 for my rack. I use NPt to do 1:1 NAT so I can have my pfsense firewall while still allowing machines behind it to have IPv6 connectivity. This works, but I have to manually configure a virtual IP for each machine. I'd really like to avoid that by just proxy NDPing the whole range.
