Win XP SP2 Setup
![[nl]](/s/countries/nl.gif) Shadow Hawkins on Wednesday, 09 March 2005 09:08:40
Hey Guys, can you please help me with my ipv6 setup om my Win XP SP2 machine?
I normally connected directly to my cable modem, and all worked fine, but since i put a router between it (US Robotics, and my machine is in the DMZ of the router) I can't get it to work!! It's driving me crazy!
Here are the logs of all the netsh commands I did. Sorry that it is in dutch, I have a dutch Win XP :S
My ipv4 local is heartbeat
My ipv4 POP is 213.204.193.2 (can ping it)
My ipv6 local is 2001:960:2:4a3::2 (can ping it)
My ipv6 remote is 2001:960:2:4a3::1 (CANNOT PING IT)
Let me know if you need more information!
thanx in advance!!

Win XP SP2 Setup
As you mention your endpoint is in the DMZ of the NAT box, and as you have an AICCU interface it seems it should work, that is if the NAT box does really have working DMZ stuff.
The following is wrong:
8<-----------------
no Handmatig 1 2001:960:2:4a3::/64 7 aiccu
no Handmatig 1 ::/0 7 aiccu
no Handmatig 0 2001:960:2:4a3::/64 5 Internet
no Handmatig 0 ::/0 5 Internet
----------------->8
And is most likely blocking your connectivity.
Stop AICCU, then do a "netsh interface ipv6 reset", check "netsh interface ipv6 show route" and see if it is still there. If it is, do a 'netsh interface ipv6 uninstall" reboot and then start AICCU (which does a 'netsh interface ipv6 install ' for you). It then should work(tm) if your NAT box cooperates.

Ok, I did a "netsh interface ipv6 reset" and all routes are gone, so that should be working fine! thanks for that!!
BUT: I still can't ping my ipv6 endpoint?
I think my problem is the DMZ of the router, is there a way to check if that really works?

Download Ethereal and see if you are actually transmitting the packets and if you get anything back.
The heartbeat mechanism works, 9 march at 09:01 and at 10:55 the tunnel was brought up. Thus only item left can be proto-41 filtering.

Shadow Hawkins on Wednesday, 09 March 2005 11:26:21
Did you restart AICCU?
and isn't the Windows Firewall in SP2 blocking stuff?
try doing
netsh firewall set icmpsetting ALL ENABLE ALL
this will enable all ICMP in/out on the firewall
[edit]
And as Jeroen Massar states it could be very well posible that Proto41 doesn't come through some where
[edit]
Win XP SP2 Setup
AICCU enables ICMP on the aiccu interface it creates.
Also, the default firewall does allow ping6 to go to the outside and back again.
That said, if you would compare the linux 2.6.11.1 IPv6 firewall compared to the XPSP2 one, then you can easily say that the XP one is better because that one does support connection tracking ;) USAGI fixes it though and with a bit of luck it will be in 2.6.12.x

Ok guys, thanks for the replies!
Here's what I so far have:
already enabled all icmp on my firewall, and as you say the AICCU should do that automatically, so that's not the problem.
I downloaded Ethereal, but cannot try it now, because I'm at my work and don't have acces to my home computer from here. So I'm gonna test that tonight and let you guys know the results.

So guys, this is what I see using Ethereal:
I don't know what to do with it, but maybe you can say if its working or not?
thanks!!
