IPv6

Hello!
I'm running m0n0 v. 1.33 on an ALIX board and I'm looking for a trouble shooting guide for IPv6.

The SIXXS tunnel with AICCU config, was up with an earlier version of m0n0, but now it doesn't work anymore.

I can ping6 the LAN and WAN I/F of my m0n0wall from a client on the LAN, but not the remote tunnel end. I get "destination address unreachable" in this case.

I see that the tunnel is up according the DHCP log:
sixxs-aiccu: Succesfully retrieved tunnel information for Txxxxx
sixxs-aiccu: AICCU running as PID 52322

Any hint for me?

what do your system and firewall logs say ? also what does the interface status page say about AICCU ?

The system log shows only PPPoE negotiations with IPv4 parameters. Looks fine and I've no IPv4 problems.

But I found a deny for router multicasts on the LAN within the FW log:
deny  LAN  fe80::20d:b9ff:fe19:f598  ff02::2 ICMPV6

The IPv6 info from the interface status page:
IPv6 address     fe80::20d:b9ff:fe19:f598%ng0/64
IPv6 gateway    2001:6f8:1c00:71::1 
AICCU address  fe80::20d:b9ff:fe19:f598%gif0/64
                          2001:6f8:1c00:71::2/128

2 I/O errors within 600 MByte outgoing packets. This value is in an acceptable range for me...

in diagnostics try ping ipv6.google.com from the WAN interface and then the LAN

Ping output from the WAN I/F:
ping6: sendmsg: Network is down
ping6: sendmsg: Network is down
ping6: sendmsg: Network is down

Try ping you gateway 2001:6f8:1c00:71::1

Are you using ayiya tunnel type and is the tunnel server up ? Check the sixxs status page

Did a PWR off/on of the router and IPv6 was up again, but dropped the tunnel after some minutes.

Changed hardware and installed m0n0 v. 1.32. It's stable since a hour ago. :-)

Thx

I'm glad it's fixed, but not by regression ....

Did you import the 1.33 configuration, or recreate it ?

I exported the config from box-1 with v. 1.33.
Installed box-2 where 1.32 was already installed and imported the previously exported config.

The hardware for both boxes is identical. - PC Engines ALIX 2D13

We can do also add. tests if required
