IPv6 Problem

[Robinski]

Hi, I have set up IPv6 in my local network (and requested an tunnel for my router)....

I just installed IPv6 unther Windows XP (2x) and Windows 2003 (1x).
but I have the folowing problem.

I can ping from my two XP machines to the Win2003 Machine
I can ping from the Win2003 Machine to it self.
I can't ping from my Win2003 Machine to the XP Machines.
I can't ping between the XP machines.

I have searched the internet but couldn't find any help....
maby somebody here can help me..

ow I only noticed differences in:

netsh interface ipv6 show address
Interface 5: Teredo Tunneling Pseudo-Interface
Adrestype  DAD-status Geldigheid   Voorkeur     Adres
---------  ---------- ------------ ------------ -----------------------------
Verbinding Voorkeur       infinite     infinite fe80::5445:5245:444f

netsh interface ipv6 show interface
Idx  Met  MTU    Status        Naam
---  ---  -----  ------------  -----  
5     2   1280  Verbinding verbroken  Teredo Tunneling Pseudo-Interface

These entrys only appear at the XP machines and not on the 2003 machine...

I have no experience working with IPv6, but do the XP machines have XP's internal firewall enabled?

Does the problem persist if you revert to normal IP?

The problem was actualy an IPv6 Firewall Microsoft installed with the latest Advanced network pack...
