Yes, this was indeed my supposition, some time later I will capture some packets and check if the theory
about the IPv6 peers sending SYNs but me not sending any SYN-ACKs back is true.

No, nothing IPv6 at all installed on my pc.
On the router, a Thomson Speedtouch 585i v6, there is no mention of IPv6 in the GUI,
however, the configuration may be saved to a "user.ini" file,
and this one contains a section called "connection.ini"
Code:
[ connection.ini ]
appconfig application=IP6TO4 trace=enabled
appconfig application=PPTP trace=enabled timeout=300
appconfig application=ESP timeout=900
appconfig application=IKE trace=disabled timeout=900 floating=enabled

You see there are 2 references to "IP6TO4"
appconfig application=IP6TO4 trace=enabled
bind application=IP6TO4 port=0
At first I thought this was the "services.ini" section,
which is a list kinda like this..:
Code:
[ service.ini ]
add name="ABC (Another Bittorent Client)" mode=client
rule add name="ABC (Another Bittorent Client)" protocol=tcp portrange=6881-6889
add name="Age of Empires" mode=server
rule add name="Age of Empires" protocol=tcp portrange=2302-2400
rule add name="Age of Empires" protocol=udp portrange=2302-2400
rule add name="Age of Empires" protocol=tcp portrange=6073-6073
rule add name="Age of Empires" protocol=udp portrange=6073-6073
add name="Age of Mythology" mode=server
rule add name="Age of Mythology" protocol=udp portrange=2300-2300
..
etc. etc...
This "service.ini " section is a list of pre-configured applications that I may use,
or create my own custom ones, so that I may tell the router e.g.
"If any packets come in destined at 6881/tcp, send these to this particular pc on the LAN"
My router uses NAT, so it has a public IP address issued by my ISP,
and a private IP address which is in my LAN sub-net.
The GUI allows me to use / create these rules.
However, that "connection.ini" section - I have a feeling these are pre-configured services that can not be edited (by the GUI at least)
- as there is no IRC, FTP, JABBER etc in the "services.ini" section.
So, another thing I'll test, is to remove those two "IP6TO4" lines
and see if that changes anything..!
Also, I'll try to disable the UPnP features.
And, btw2:
I'm currently building a new pc for a friend, which has Windows 7 installed.
IPv6 is by default enabled on this one.
I have just connected it to the LAN, and while it has got an "internal" IPv4 address from
my Speedtouch's DHCP pool, it has also got a IPv6 address:
Code:
Ethernet adapter Local Area Connection:
Connection-specific DNS Suffix . : lan
Link-local IPv6 Address . . . . . : fe80::abcd:abcd:abcd:abcd%13
IPv4 Address. . . . . . . . . . . : 10.0.0.7
Subnet Mask . . . . . . . . . . . : 255.255.255.0
Default Gateway . . . . . . . . . : 10.0.0.1
Tunnel adapter isatap.lan:
Media State . . . . . . . . . . . : Media disconnected
Connection-specific DNS Suffix . : lan
Tunnel adapter Local Area Connection* 11:
Connection-specific DNS Suffix . :
IPv6 Address. . . . . . . . . . . : 2001:0:5ef5:73bc:cdef:cdef:cdef:cdef
Link-local IPv6 Address . . . . . : fe80::cdef:cdef:cdef:cdef%13
Default Gateway . . . . . . . . . : ::
(The "abcd:" and "cdef:" are of course edited for my protection)
But as you can see, the one IPv6 Address that is not "Link-local"
does indeed start with "2001:0:5ef5:73bc:"
- just like 3 of the ones in the list that I posted in the previous post.
And I don't live in the US!
So now I wonder if there is an error with Vuze's "CountryLocator" plugin,
- or maybe with the lists it uses.
As I wrote in the previous post,
"Network Number 2001:0000:0000:0000:0000:0000:0000:0000 - 2001:01FF:FFFF:FFFF:FFFF:FFFF:FFFF:FFFF"
is supposed to be located in "Country United States (US)"
- according to Person NIC Handle Whois Lookup
But either this is wrong, or else my router or Windows 7 is wrong.
I also wonder where it got that IPv6 address from..
Well - I'll test those things I mentioned as soon as I finish my friend's pc! :-)
