IPv6 Issues since upgrading

poppadum

I have what looks to be the same issue - no IPv6 default route since upgrading to 2.7. pfSense does think my IPv6 gateway is up, probably because I've set a monitor address which is pingable from the LAN.

My pfsense is virtualised under Proxmox and I think the link-local address of my pppoe0 interface has changed since upgrading to 2.7.

The gateway IPv6 address shown doesn't seem to be valid for interface pppoe0:

# ifconfig pppoe0
pppoe0: flags=88d1<UP,POINTOPOINT,RUNNING,NOARP,SIMPLEX,MULTICAST> metric 0 mtu 1492
        description: WAN
        inet6 fe80::3421:f898:4e49:5f2b%pppoe0 prefixlen 64 scopeid 0x8
        inet6 fe80::ec5e:b8ff:fe3a:ae7c%pppoe0 prefixlen 64 scopeid 0x8
        inet6 2001:8b0:1111:1111:0:ffff:51bb:1aef prefixlen 128
        ...

I'm not sure where it's getting that gateway address from - it's set to dynamic in the web interface. It is in file /tmp/pppoe0_defaultgwv6 but I thought that was regenerated every boot?

@jordanp123 said in IPv6 Issues since upgrading:

I found that manually adding a ipv6 route using the link local gateway address will let mine work

That fix also works for me. In my case if I enter

route -6 add default fe80::ec5e:b8ff:fe3a:ae7c%pppoe0

IPv6 routing starts working fine from inside the LAN.

Just spotted this in the ppp log on the date I did the upgrade:

Jul 27 17:07:25	ppp	13981	[wan] IPV6CP: rec'd Configure Request #0 (Ack-Rcvd)
Jul 27 17:07:25	ppp	13981	[wan] IPV6CP: SendConfigAck #0
Jul 27 17:07:25	ppp	13981	[wan] IPV6CP: state change Ack-Rcvd --> Opened

Jul 27 17:07:25	ppp	13981	[wan] ec5e:b8ff:fe3a:ae7c -> 0203:97ff:feba:0900

Anyone know why ppp seems to be rewriting the link-local address?

jordanp123

None of the systems I'm on are using ppp but so far its two systems that I've had to fix with the ipv6 issue, both the same thing.

Can someone please explain what is happening here?

Check the routing tables, make sure there is a valid default route for IPv6. If not make sure the default gateway in System > Routing > Gateways is set to WAN_DHCP6.

It's valid to have only a linklocal address on WAN. If your ISP is passing only a prefix they can route that to you across the linklocal address. You must have a globally routable IPv6 address somewhere though.

jordanp123

@stephenw10

I tried setting the default gateway under Gateways to both automatic and the WAN_DHCP6 both failed to route, I had to manually add a static GW or use the add route option to get the two I was working on to route.

stephenw10

And before that the routing table was showing no default IPv6 route?

Do the logs show a new route being passed when it connects?

jordanp123

@stephenw10

I'll change the gateway back to the default one this evening and get you some answers, I can't change it back right now, since ipv6 is being used.

jordanp123

@stephenw10
I was able to catch some time while no one was using the system and test. Switching to WAN_DHCP6 after setting the static GW results in connectivity, however if the pfSense is rebooted with WAN_DHCP6 set as the default GW then a default route isn’t installed on reboot.

stephenw10

Ah, then I would check the dhcp and routing logs for errors when it first connects at boot. There is likely something preventing it adding the default route at that time.

@stephenw10
Going through the logs on boot the only errors I see are the following:

Hmm, nothing jumps out there as a specific gateway/route error. How does that compare with when it creates the route correctly?

That looks like the successful case. What does it show when it fails?

jordanp123

@stephenw10
It failed, I have no IPV6 default route.

@jordanp123 said in IPv6 Issues since upgrading:

Hmm, yet it is adding addresses and knows what the gateway is....

How does that compare with the successful case?

@stephenw10
