IPv6 ?

I'll ask the question for the WCS, but I think it extends to the whole wireless product line.
Does WCS support management via IPv6 connected browsers? Can it manage APs
that have v6 addresses? Can CAPWAP work over v6? If not, where is this on the road map?
In v6 enabled networks, RAs (router advertisements) from misconfigured clients can
be a problem. Can WCS give a command to the APs and controllers to block client RAs?
Thanks.

In an IEEE 802.11 dual-stack environment, IPv6 Unicast and Multicast traffic are transparently forwarded by Cisco Wireless devices.
• Controllers (4402-12, 4402-25, 4402-50, 4404, WiSM, 3750G, NMWLC)
• Access Points (AP1130, AP1240, AP1000, AP1500, AP1300 in AP mode only)

How can I disable 1142N from providing IPv6 access ?

subject says it all, I failed to find the command in configuration..

Hi Andre,
As per my knowledge, you cant disable from ur AP.
Ipv6 is currently not support on any of the Cisco AP's in autonomous mode. However, they will be able to pass ipv6 traffic.
May be newer IOS version like : Cisco IOS Release 15.2(4)JA supports IPv6 protocols

PMTU discovery in IPv6 based on IPV6_RECVPATHMTU in Solaris 10

Our application works with raw sockets and needs to discover PMTU of IPv6 paths.
According to the RFC-3542 (http://tools.ietf.org/html/rfc3542, section 11) the socket option IPV6_RECVPATHMTU allows applications to know about the change of path MTU by receipt of new ancillary data item (IPV6_PATHMTU) which is delivered to recvmsg() without any actual data. Following construction should be used to enable this option:
int on = 1;
setsockopt(fd, IPPROTO_IPV6, IPV6_RECVPATHMTU, &on, sizeof(on));In the online Sun documentation I found that this socket option is supported since Solaris 10 (http://docs.sun.com/app/docs/doc/816-5177/ip6-7p).
However, in our test this socket option appears to be not working. After decrease of the PMTU via ifconfig and sending a big enough packet an ICMP (Packet Too Big) is received but there is no event with ancillary data item on the socket.
One peculiarity that may be essential is that our application binds to a specific port in a raw socket (i.e. to IP address : port pair).
Does anyone have information if the IPV6_RECVPATHMTU socket option is really supported in Solaris 10?
Probably, ICMP should be off to be able to receive this event with ancillary data on the socket?
Will appreciate any ideas how to make it working.
Thanks in advance,
Mike.

Hi,
I have a Sunfire V100 - and have the exact same problem. The settings are correct; I have configure dual-NIC cards many times in the past - but this issue is simply eluding me. I can swap in a Linux machine in router / ip forwarding mode and there are no problems, but when I put back in the Sunfire I encounter the same issues you have.
In effect, packets from the LAN arrive at the NIC on the Solaris machine, but then don't get forwarded to the other NIC's gateway. I'm at a loss, but I have seen this problem pop-up (without answer) a half-dozen times in this forum alone, and multiple times on different support sites. Did you (or anyone) ever come across a solution for this? Is this not some easily overlooked yet possibly cryptic flag or variable that I've missed? Anyone?

Cannot deploy to localhost:7001 / how to remove the IPV6 from Jdeveloper ?

Hi,

Direct Access on Windows Server 2012 R2 and IPV6

I have a question about IPV6 and Direct Access in Server 2012 R2. Without using UAG is it still mandatory to have IPV6 enabled in the intranet?
Kristopher Turner | Not the brightest bulb but by far not the dimmest bulb.

Hi,
DirectAccess uses IPv6 with IPsec to create a secure connection between DirectAccess client computers and the internal corporate network.
However, DirectAccess does not necessarily require connectivity to the IPv6 Internet or native IPv6 support on internal networks. Instead, it automatically configures and uses IPv6 transition technologies to tunnel IPv6 traffic across the IPv4 Internet (6to4,
Teredo, IP-HTTPS) and across your IPv4-only intranet (NAT64 or ISATAP).
For detailed information, please view the link below,

Cisco asa 5505: No traffic lan to wan with IPv6

Hello everybody,
I have a Cisco ASA 5505, public ipv6 in outside interface, private ipv6 in LAN, from router I can ping any ipv6 in Internet and ping my LAN ipv6. Traffic doesn't go through router.
This is my configuration.

ipv6 route outside ::/0 xxx:yyyy:67:36::1
Am I omitting anything?
Thanks in advance for the help.
Jos P

Since you're using IPv6 private addressing (fc00::) on the inside, you need a dynamic NAT entry to translate your private IPv6 addresses to a public one.
Alternatively, you could just use a subnet of your registered IPv6 block for the inside network and not worry about NAT.

How do I configure ISP native IPv6 connectivity?

Hi!
I'm a network engineer for SECOM, an ISP in Southeastern Colorado. We will be making native IPv6 connectivity available to residential subscribers soon, and I've been tasked with verifying support for our IPv6 platform on home router products.
I have an AirPort Extreme purchased new in November of '09 that is running version 7.5.1, which I believe is completely current.
Under the IPv6 tab in my Advanced settings, I have the following configuration:
IPv6 Mode: Router
Block incoming IPv6 connections: NOT checked
Configure IPv6: Manually
WAN IPv6 Address: fdXX:XXXX:XXXX:a000::2
WAN IPv6 Prefix Length: 64
IPv6 Default Route: fdXX:XXXX:XXXX:a000::1
LAN IPv6 Address: fdXX:XXXX:XXXX:c000::1
(As you can see, I'm using ULA's for testing purposes, and I've replaced the global bits with X's for security.)
The problem is, if I plug a host into one of the LAN ports and assign it an address from the same /64 subnet (e.g. fdXX:XXXX:XXXX:c000::2), the host can't ping the Airport's assigned LAN address.
It can ping:
* the Airport's link-local IPv6 address, and
* the Airport's IPv4 192.168.x.x address
Also (and I'm gratified that this part is working), my CE router can ping the Airport's WAN IPv6 address!
So my question is, is there something in the IPv6 configuration I'm misunderstanding? Has anyone else gotten native statically-configured IPv6 working on the AirPort Extreme?
Thanks very much in advance,
John E. / SECOM
P.S. - I have verified with a packet capture that the AirPort extreme is not responding at all for the configured LAN IPv6 address; i.e., the ICMPv6 neighbor solicitation goes unanswered.
P.P.S. - I have tried a Windows 7 host, a Windows XP host, and an IPv6-certified multitester from JDSU. All exhibit the same symptoms.

I have follow your instruction to connect to my ISP as it shows the following message:
Serial connection established.
using interface sppp0
connect: sppp0 <--> /dev/ttya
local IP address xxxxxxxx
remote IP address 1.1.1.1
But when I ping www.sun.com, it shows:
www.sun.com unknown.
I start Mozilla and it said www.sun.com not found etc...
What has gone wrong?
Do I have to configure some files such as:
/etc/resolv.conf
/etc/hosts
/etc/hostname ?
or any other steps that can help me to connect to the internet?
Thanks...

How to handle changing IPv6 network configurations

Hi,
I run a Mac Mini as a server with OS X Server 10.8.5/2.2 on it using an internet connection with DS-lite. The server runs fine on a private IPv4 and a public IPv6 assigned by the ISP thrugh my router. Now from time to time (on some really odd days 5 times a day) my ISP decides to change my IPv6 prefix and as a consequence the IPv6 of my server. This results in a warning and some services seem to work not always properly. When I handle the warning and update the network configuration (although all relevant pieces of configuration that are shown along this proces remain unchanged), everything is back to normal.
Now I wonder whether there is better way to handle changing IPv6 prefixes while everything else is unchanged? Any thougths? Thanks. Steffen

I'll add my 2 cents too Sudheer...
I suppose your versioning strategy should take into account your particular circumstances, impact analysis, ESB architecture etc...
In our case it makes sense to version the service operations because we have some consumers that want to stay on the older version & other that want to move with the changing versions...
We've noticed that SAP, with the standard delivered enterprise services also version step the service operations so you esentially have 2 service contracts but one that caters for additional fields/functionality. The consumer uses the service operation that they prefer.
The other possibility, if you are in a position to make the new fields 'optional' then you could do that without impacting all the consumers, the consumers that have the additional info to pass in the request can do so & the other consumers can carry on business as usual.
Then you could also version step the entire service, that would entail making use of a new software component version but this would entail new endpoints & depending on your architecture it could impact all your consumers. If you're using an integrated ESB architecture, your consumers would have one endpoint & the ESB would route the request to the relevant service version.
So you could minise impact on the consumers & develop a good versioning strategy depending on what your current situation is.

How can I disable IPv6 EUI randomization with group policy?

I need to turn off IPv6 EUI address randomization. It can be done in netsh (a few commands) or powershell (Set-NetIPv6Protocol -RandomizeIdentifiers Disabled). How can I do this in group policy without scripting?

Hi Jordan,
Before going further, I hope that the suggestion provided by Martin can be helpful.
It seems that we can't configure this setting via native policy.To configure IPv6 settings,
we need to download ADMX files for IPv6. However, per the following article, the IPv6 settings that can be configured are:
Enable all IPv6 components
(Windows default)
Disable all IPv6
components (the setting you probably want)
Disable 6to4
Disable ISATAP
Disable Teredo
Disable Teredo and 6to4
Disable all tunnel
interfaces
Disable all LAN and PPP
interfaces
Disable all LAN, PPP and tunnel
interfaces
Prefer IPv4 over IPv6

How can i disable ipv6 in OL7?

Hi everybody,
how can i disable ipv6 on my OL7 box?
In /etc/sysctl.d i have test it with the file: ipv6.conf:
net.ipv6.conf.all.disable_ipv6 = 1
net.ipv6.conf.<interface>.disable_ipv6 = 1
But this doesnt work.
Does anybody know how can i disable IPv6 in Oracle Linux 7?

What I would recommend is not to set implicit or redundant parameters:
net.ipv6.conf.all.disable_ipv6 = 1
net.ipv6.conf.default.disable_ipv6 = 1
There is no need to disable the "default" interface, since it is already included in the "all" statement.
I do not know, but there could be a possibility that such statements disable the network card in question, but in turn enable every other. In such case, your 2nd statement invalidates the first. Perhaps that was was part of the problem when using your other configuration.

How can I turn off IPv6 temporary addresses in a enterprise environment

So in a default configuration Vista and Windows 7 clients will use IPv6 temporary address (per RFC 3041), but I would like to be able to disable this with a GPO.
I know I can do this by using a startup script tied to a GPO using the netsh interface ipv6 set privacy state=disabled store=persistent but I really do not want to run a logon script especially when as you can see in the command it is a persistent
setting.
Any ideas on using a registry based GPO for this?

Hi,
OK, I understand what you want. But after I use the Process Monitor to capture the behavior, I found that a lot of registry keys would be changed. So you can not set it via registry unless the IPv6 is disabled.
Thanks for understanding.
Please remember to click “Mark as Answer” on the post that helps you, and to click “Unmark as Answer” if a marked post does not actually answer your question. This can be beneficial to other community members reading the thread. ”
Thank you again for the answer.
As a follow up question... How does one suggest/request a change in default behavior in a MS product?
While the RFC 3041 addresses might be nice to have for the average consumer they are not ideal in a enterprise environment. I have found that the temporary addresses will register in DNS, but this doesn't completely solve the issue of tracking and accountability,
you would still need a application to query, correlate and store that information.
So it would be nice if the business versions of Windows Vista/7/2K8 and the next client OS would not have this behavior by default.

How to configure DNS to support ipv4 and ipv6

I have a 2008 r2 domain controller in my lab.
i'm doing Exchange 2007, 2010 and 2013. I have mix Windows 2008 r2 servers for other applications.
i'm running into issues where i'm thinking it is time to have both IPV4 & IPV6 to run on all lab machines.
I can't get a clear picture on how to accomplish a mix environment. in the DNS administrator do I create a new "reverze lookup zone" with only the IPV6? or do I have to create a new record in the "forward lookup zone" to with both IPV4
& IPV6 which the later points to the new "reverse lookup zone".
I see a lot of internet article but little on "how to".
or on the DC should I enable the DHCP role to support the IPV6?

1. You assign an IPv6 address to the domain controller/DNS server
One method is letting this site (legitimate) create a random private IPv6 range for you:
http://www.simpledns.com/private-ipv6.aspx
For example:
fd06:fcde:8b4e:d6bd:xxxx:xxxx:xxxx:xxxx
You can configure the x's like this (you cannot leave the x's there):
fd06:fcde:8b4e:d6bd:0000:0000:0000:0001
If you close and open IPv6 properties, or do an "ipconfig /all" you'll see that the IPv6 is abbreviated as follows:
fd06:fcde:8b4e:d6bd::1
That's normal.
If you look in your forward lookup zone, you'll now see this IPv6 address (you may have to register that manually - ipconfig /registerdns - but it seemed to happen automatically for me.
So there is no need to create a separate forward lookup zone for IPv6.
OK, but what about the reverse zone?
2. Create reverse lookup
In DNS Manager (what you call administrator), right-click on reverse lookup zone, select New Zone, click, Next, Next (default values are fine) until you choose between IPv6 and IPv4. Selecft IPv6 of course.
Then enter your prefix as shown here:
That's it. The reverse lookup information is configured automatically (your prefix " backwards").
Now, unlike with the forward lookup zone, my domain controller does not seem to be registering its name in the reverse IPv6 zone: there's only the SOA and NS record.
But that's another question.
Please mark as helpful if you find my contribution useful or as an answer if it does answer your question. That will encourage me - and others - to take time out to help you.

Hi there!
Has Comcast stopped assigning delegated prefixes for users who request them? I had my router setup to request a /60 via IA-PD but just today it appears to have stopped. I'm still getting an ipv6 address on the dhcpv6 solicit, but no more delegated prefixes. Thinking that the problem might be solved with a firewall software update, I upgraded to the latest release version but the same problem persists. Here's my IAID/DUID to aid in tracking down the issue.

Getting error while accessing a webpage by using link local address of ipv6

Hello,
I want to access my login.jsp by using ipv6 address.
when i am accessing my web page by using loop back or localhost6(like the following) it is working.
http://[::1]:8080/test/login.jsp //for loopback
http://localhost6:8080/test/login.jsp
But when i am accessing my webpage by using link local address as following i am not getting my web page.
http://[fe80::201:6cff:fe0f:d7ae%eth0]:8080/test
or
http://[fe80::201:6cff:fe0f:d7ae]:8080/test
For the above case is there any solutions????

Whatever i have mentioned these are correct. My ipv6 address is also correct.From browser only i am accessing.>
Not a Java issue, then. Your problem I'm afraid.
But how do you know they're correct? Given that one of them isn't working, I'd triple check it if I were you.

After upgrading my time capsule to 7.6.3 I can no longer access my IPv6 tunnel broker.

My Hurrican Electric Tunnel Broker IPv6 Connection worked fine with 7.6.1, but after upgrading the firmware on my Time Capsule to 7.6.3 I get an error. "There was an error with the IPv6 tunnel endpoint. Wait for the service to be restored and try again. Contact your service provider if the problem persists." It worked before the upgrade. All settings verified. Now it doesn't work.

https://discussions.apple.com/thread/4787229?start=30&tstart=60
I cannot find the reference.. but the fix is clear.. return poste haste to 7.6.1
And wait for the next upgrade installment.. frankly I am amazed this hasn't been pulled. If this is what Apple consider tested firmware updates.. we are all down the tubes.
