Ticket ID: SIXXS #697474 Ticket Status: Invalid PoP: simbx01 - Amis (Maribor)
POP does not route packets from my subnet
![[si]](/s/countries/si.gif) Shadow Hawkins on Thursday, 27 March 2008 15:56:20
Setup:
Home router acting as NAT between my LAN and ISP (ADSL connection).
heartbeat mode tunnel endpoint running on the same router.
tunnel id is T14647
I also have a subnet : R6338
the router runs radvd and my LAN host (usually) have working IPv6.
Problem:
After a DSL breakup everything works again except some IPv6 issues.
ping ipv6.google.com from the router : WORKS
On a host on the LAN :
ping cl-363.mbx-01.si.sixxs.net WORKS
ping gw-363.mbx-01.si.sixxs.net WORKS
ping ipv6.google.com does NOT work
I had a similar problem before and posted on the forum : https://noc.sixxs.net/forum/?msg=setup-694393
There Jeroen Massar said, that restarting the tunnel is not the correct solution and I should create a ticket instead.
- "aiccu test" results, all check (note: my router has no traceroute6, I used ping6 to test noc.sixxs.net and www.kame.net accessibility)
- OS info :
router: OpenWRT 1.0 (White Russian)
host: Windows 2003

NOTE: while running "aiccu test" for this report, somehow my tunnel broke (the sixxs interface disappeared). So I had no choice but to restart it ("aiccu stop ; aiccu start"), which, as described in the forum post, solved the problems.
PS: I have an idea how to simulate this situation again. Please advise.

POP does not route packets from my subnet
It has nothing to do with the PoP. It is a problem in the AICCU client which has been resolved but has to be released for non-Windows platforms:
"Don't use a connected UDP socket for AYIYA and heartbeat traffic"
The "Tunnel Restart" you mentioned is a *CLIENT* restart, while the way you write it it looks like you are doing a tunnel up/down through the webinterface.
As you are behind a NAT you should be using AYIYA.

I am not behind a NAT.
POP does not route packets from my subnet
You have to, as you have RFC1918 addresses on your interface, and they really won't work on the global internet.

My tunnel endpoint is not behind NAT.
But it _is_ dynamic, that's why I use the heartbeat protocol instead of static.
Currently my IP address is 92.37.52.118 and as you will surely see, it does "work on the global internet". You can test by telnetting to it.

By "it" in the second line I mean "the IP address of the host running aiccu".
POP does not route packets from my subnet
There are only RFC1918 addresses in your routing output.
As such, you can't have a public address on the localmachine, and you are behind a NAT.

Shadow Hawkins on Monday, 19 May 2008 13:54:02
The PC is behind an IPV4 NAT.
The router is not.
I am at my workplace ;-)
I (and others, see forum) have this problem again. Is the new version of aiccu available yet ? http://downloads.openwrt.org/backports/0.9/ still has the old version.
Should I just restart aiccu ?

David
