[SOLVED] My OPNSense cant route IPv6
« on: March 12, 2021, 11:08:03 pm »
Hi, I have a fibre connection of 50/10 Mbit.
My ISP doesn't allow me to configure the modem so the only thing I can do it configure a DMZ pointing to my OPNSense.
Recently my ISP implemented IPv6 and I discovered it by accident while I was connected directly to the GPON router.
So I configured OPNSense to get an IPv6 address via DHCPv6.
It now have IPs v4 and v6 on WAN.
I can ping to Internet from WAN interface, but when I try to ping from LAN or from a PC on LAN it doesn't work.
I noticed that the default IPv6 gateway it fe80::1 and not the IP of the interface or a link-local IP.
The ISP is ginving me a /64 prefix.
I've been making lots of experiments to try to make it work, but nothing. The best thing I get is pinging from WAN.

May be someone can give a clue to test farther.

Thank you

64 prefix means you are limited to 1 subnet = wan, so you can not setup ipv6 for your lan/dmz.

"Interfaces -> Overview -> WAN -> IPv6 delegated prefix"

If you have a prefix <=63 you have to setup router advertisement for SLAAC.

How can I do to configure SLAAC. Please excuse my ignorance.

SLAAC is automatic and on by default. Have you asked your ISP if they are supplying a prefix delegation as well? Might be that they are and you need to adjust some settings to enable it. Check with your ISP and find out how they have implemented Ipv6. If they are only giving a single /64 they are brain dead and I would try and find another ISP

Hi @marjohn56, unfortunately here in Argentina it is just like you last said: they are brain dead.

Trying to get some info from the employees that pick up the phone or answer the emails is a waste of time.

If I want a decent service I have to pay for an enterprise grade service that is far unaffordable to me.

That's the reason why I have to make this without ISP help. They are not going to help because the service just work as they expect. Local PCs have dual stack Internet.

When OPNSense ask for an IPv6 vía DHCPv6c, it receives an IP and a delegated prefix. I can see that in Interfaces > Overview > WAN

This is the what I see:

IPv6 link-local                  fe80::20c:29ff:fe72:f8/64
IPv6 address                  2803:xxxx:xxxx:xxxx:20c:29ff:fe72:f8/64
                                       2803:xxxx:xxxx:xxxx::1/128
IPv6 delegated prefix     2803:xxxx:xxxx:xxxx::/64
IPv6 gateway                 fe80::1

One thing I tested is setting WAN and LAN IPs manually.
Doing a packet capture on WAN while sending a ping to google.com from WAN itself, I can see the conversation with the response, but when I send the ping from LAN, OPNSense doesn't respond to neighbor solicitation that the IPSs router make.

PING from WAN:

No.   Source                                 Destination
1     2803:xxxx:xxxx:xxxx::1       2800:3f0:4002:808::200e
Echo (ping) request id=0x083a, seq=0, hop limit=64 (reply in 4)

2     fe80::1                                 ff02::1:ff00:1
Neighbor Solicitation for 2803:xxxx:xxxx:xxxx::1 from 50:6f:77:7d:dd:57

3     fe80::20c:29ff:fe72:f8          fe80::1
Neighbor Advertisement 2803:xxxx:xxxx:xxxx::1 (rtr, sol, ovr) is at 00:0c:29:72:00:f8

4     2800:3f0:4002:808::200e    2803:xxxx:xxxx:xxxx::1
Echo (ping) reply id=0x083a, seq=0, hop limit=116 (request in 1)

PING from LAN:

No. Source                                  Destination
1    2803:xxxx:xxxx:xxxx:1::1     2800:3f0:4002:808::200e
Echo (ping) request id=0xf8b6, seq=0, hop limit=64 (no response found!)

2    fe80::1                                 ff02::1:ff00:1
Neighbor Solicitation for 2803:xxxx:xxxx:xxxx:1::1 from 50:6f:77:7d:dd:57

3   fe80::1                              ff02::1:ff00:1
Neighbor Solicitation for 2803:xxxx:xxxx:xxxx:1::1 from 50:6f:77:7d:dd:57

4   fe80::1                              ff02::1:ff00:1
Neighbor Solicitation for 2803:xxxx:xxxx:xxxx:1::1 from 50:6f:77:7d:dd:57

5   fe80::20c:29ff:fe72:f8        fe80::1
Neighbor Solicitation for fe80::1 from 00:0c:29:72:00:f8

6   fe80::1                                fe80::20c:29ff:fe72:f8
Neighbor Advertisement fe80::1 (rtr, sol)

I can see in the second capture that ISP router makes 3 neighbor solicitations and nobody answers, so it gives up and it doesn't forwards the ping response. But I'm not sure of my conclusions.

In the dhcp6c settings of the WAN interface is an option for SLA Len or as it's shown there "Prefix delegation size", set it to 64, and see if that helps.

It is already set to 64, as it comes as default. I made tests with different values and with "none", but now os set to 64.

Can you go Interfaces->Settings, there is a section for dhcp6c, set the log level to debug and save, you'll then need to reboot. When it comes back up, give it 60 seconds or so to settle then go to the system logs and add a search filter dhcp6c, then post the results so we can see what gives.

Are you seeing a GUA address on the LAN?

In response to your second question, I can see an IPv6 address on LAN. From the Interfaces > Overview > LAN

IPv6 link-local   fe80::20c:29ff:fe72:ee/64
IPv6 address   2803:xxxx:xxxx:xxxx:20c:29ff:fe72:ee/64

EDIT: LAN IPv6 is set to track WAN interface

And I did the dhcp6c debug as you asked. Here it is the filtered log:

That look good.  If you can ping from the wan then the gateway is working. Are your LAN clients getting GUA by addresses?

No... I didn't start dhcp nor ra service on lan yet... should they receive an address?

EDIT: I don't see RA nor DHCPv6 to start anyway

Just let it do its thing, turn off the manual override, radvd and dhcpv6 will be set for you. Then check to see if clients are getting a gua.

Sorry, misread your message, if you have the LAN set to track the wan interface, then radvd and dhcpv6 should be running already.

Services radvd & dhcpv6 are running as you pointed out.

My Windows 8 is getting the following:

IPv6 Address                      2803:xxxx:xxxx:xxxx:a57e:5d63:f83b:9e0d
Temp IPv6 address             2803:xxxx:xxxx:xxxx:b1ab:fe5b:4ec4:e288
IPv6 Link-local address       fe80::a57e:5d63:f83b:9e0d%41
Default gateway IPv6         fe80::20c:29ff:fe72:ee%41

One thing I have just noticed is that I can't ping to router GUA addresses but I can ping to link-local addresses
