DNS Not Working IPV4 IPV6 Not Connected?
Jan 11, 2013
has quite frankly gotten me absolutely annoyed . I've tried just about everything, from using the netsh commands to changing the dns to 8.8.8.8 or that other one or the other. Nothing is working, I unplugged the router, problem persists, I disabled IPV6 problem persists, I restore, problem persists. The only clue I have is my router, and mysteriously, there are TWO of my computer on it. It might be nothing but most certainly has caught my attention. Also, it gives me this info about my media being disconnected

I have a Dlink DIR-825 B1 with firmware 2.05NA. I recently reset it to factory defaults to make sure I didn't misconfigure something.
I have been struggling to get a IPv6 in IPv4 tunnel working with tunnelbroker.net. I think the issue is a problem with the router itself and i'm not sure how to get it fixed.
All of my machines were getting IPv6 addresses (both windows, mac, linux) but none of them seemed to work. All I was able to do was ping the gateway itself using the local lan address. In each case they were missing a default IPv6 route. If I added a default route then it would work.
I started looking at the packets using a network sniffer and the Router Advertisements all had a Router lifetime value of "0" which is RFC4816 speak for "don't use this router as the default router". So Windows/Linux is exactly right by not setting a default route.
The strange thing was that when I reboot the router I would briefly get a router advertisement with a lifetime of 1800s, the corrert prefix and dns server but then another router advertisement would come along 5 seconds later with a router advertisement of 0.
I have TCP' Other observations
... using 6to4 I would get working IPv6 address. The difference again seemed to be the Router Lifetime. But I want to use a permanent tunnel. I have found 6to4 unreliable.
... the router never responds to router solicitations. It only sends a router advertisement when it wants to.
... the router never responds to DHCPv6 when that is configured.

I have a dell inspiron 15 and I've been having trouble fully connecting to my wireless internet. It says I have signal but gets stuck on identifying the network and I have limited IPv4 and IPv6 connectivity.
Here's the ipconfig if you can identify the issue with it:

I've just want to confirm if I can protect a router (telnet and ssh) putting 2 ACL's (one IPv4 and other IPv6) on the same line vty. Something like:
line vty 0 4
access-class hostsIPv4 in
ipv6 access-class hostsIPv6 in
Do I have to use named ACLs?

our company backbone is hp 5406, and desktop switches are hp 2510 currently we are working with ipv4.if we want to start use IPV6 for test environment, what’s things we need to enable in our backbone/regular switches.i mean for example if we want to set static IPV6 address for 2 servers and send ping between them, or even make new vlan with IVP6 subnet, and use it like regular vlan but with static ip's(until we got ipv6 dhcp).i have hp 5406 manual for IPV6 but i can't understand what i really need to do for start using IPV6.

Recently I wanted to setup IPv6 for my home network. I signed up for tunnelbroker.net service and was provided with IPs. Then I configured the IP address in my DIR-615. But It's not working..
Screenshot of IPv6 config (router) : Screenshot of my Win 8 network Config : I also tested at [URL] but failed...

I currently have ipV4 as the setting on my DIR-825. Other posts seem to want ipV6 which is more secure but is not possible with a DIR-825 Rev A1. I have two routers, a primary router (DIR-825 Rev B1) capable of ipV6 and a secondary router (DIR-825 Rev A1). If I implement ipV6 on the Rev B1 router but keep ipV4 on the secondary router, will this improve the security, or will it just mess things up so nothing works?Certain devices (cell phones and most Tablets) don't deal with ipV6 very well at all. The ones I have tested flat don't connect to the wireless network if the router is set at ipV6. Is ipV4 adequate for a Home/Small Business Network when trying to implement Remote Access and VPN?

ASA 5520 running 8.2
Is it possible to do static (inside,outside) with the outside address being IPv6 and the inside IPv4?
If yes, is it possible to do this in parallel with an existing static mapping that goes IPv4 to IPv4?

Would like to learn from you what tools I could use in a Network that provides IPv6 visibility and also completely blocks IPv6 from being tunneled through ipv4 only networks.
I have tested this from Linux running some internal penetration test apps,but specifically running Teredo tunneling in Local LAN that is able to completely bypass security paremeters such as websence filtering servers and be able to accessing internet IPv6 sites, even its equivalent IPv6 address based on its IPv4 PAT address could be pinged from outside.. is like the PIX firewall never existed - wide opened door .
Blocking in outbound and inbound direction udp ports 3545 and 3544 seem to done the trick in dropping IPv6 at the PIX/ASA from being tunneled out or in.. Is this so ? Realy ? not to fast!! None of our local systems - users PCs or servers have IPv6 stack enabled as a policy, however, in reality this poses a serious thread.
For example, Teredo tunneling running in a host inside LAN say by a user who is a hacker can use different UDP ports from the standard listening udp 3545/3544 ports, host will still be able to tunnel IPv6 through IPv4 again, in this case I want to have tool or a strategy that can detect this internally beside being blocked at the firewall, I am looking at AIP for our ASAs would this help? What other tools could I utilized to have some sort of IPv6 awareness in our LAN without having to rung IPv6 that can provide some visibility of this invisible traffic in IPv4 LANs.

I'm working on a computer that has no connectivity on wired or wireless connections. the wired eth card is a broadcom netlink card and the wireless adapter is an atheros ar5007eg. I found the drivers for the wireless on acer.com and removed the driver that was on here at first and put the one from acer. i cant find a network in range but device manager says its working fine. Then I found out the wired connection isnt working either and im getting the same messages from windows troubleshooter. It says both are "experiencing driver or hardware related issues and "make sure your internet protocol bindings are correct - ensure that ipv4 and ipv6 are selected in the config for the network adapter". it links me to the connection properties and ipv4 and ipv6 are checked off for both. futhermore, in the connection status window it says i have no ipv4 or ipv6 connectivity.

No changes made but router will lose all information for IPv connectivity. I have paid twice to support to fix this issue and it still occurs every few months. I tried rebooting router, and doing an IP Release/ Renew and router does not get IP address.

I have a virtual machine running in my desktop which connected on the gigabit lan port on EA4500 with firmware 2.0.37.What I want to be able to do forward a port that came from an external ipv4 address to the ipv6 address and a different port to my virtual machine (to remote desktop port 3389).The reason I want to convert the traffic to ipv6 is because virtual machine is running vpn and is not reacheable through ipv4 (unless bunch of routes are setup and things get complicated etc). I verified my phsical server and virtual server get both ipv6 ip addresses through ipv6 tunnel from comcast. Without tunneling I could not get ipv6 setup using automatic mode with comcast, it simply did not work for some reason.

My laptop is not connecting to the internet, I know that it is not a router problem as my mine PC and Notebook are connecting with no issues.I have removed all router devices as had an new once once it was last working.I tried this morning to set it up again without success. I have compared to setting with my pc and have found the difference is with the IPV6 connectivity.

Lenovo G550 with windows 7 shows that the Internet is connected but the IPv4 and IPv6 connectivity says no network access. I updated and reinstalled drivers, typed in some cmd command and restarted computer with no success. I also called tech support and they had me go into safe mode, the Internet didn't work there so he said it was a driver problem but wouldn't fix it.

I have a d link dir 615 "ipv6 ready". My internet provider give tome a native ipv6 /48. I configure the router with my ipv6 /48 address the internal propagation of the address is good.
On the status ipv6 page all seems OK marked "connected" but I can't have an ipv6real connection and my provider say to me that i am not connected.
Is there a known problem of connection between an public /48 and the internal /64 and if so could it be corrected.

I am using my DIR-825 as a switch and AP. I have turned off DHCP and plugged the internet into the lan-1 port. This works perfectly for IPv4, but I cannot get IPv6 to work. On the outside there is native IPv6 running radvd. How should I configure IPv6 on my DIR-825?

I'm having several issues with IPv6 and ZBF. I've narrowed one of them to a very simple setup. I tried 15.1(4)M in GNS2 and 15.1(4)M3 on a 1812.
The setup is
[PC] ----- [R1] ------ [R2]
R1 and R2 are interconnected by IPv6 only and there is a tunnel over that link to carry IPv4 from R2 to PC.
And I'm trying to ping PC from R2 with IPv4. We're looking at the R1 config mainly. (the other are included for completeness)
When I try to ping the PC from R2, I get this on R1 console:
%FW-6-DROP_PKT: Dropping icmp session [::]:0 [::]:0 on zone-pair zp_vpn_to_lan class cm_icmp with ip ident 0
Which really doesn't make much sense because zone vpn and zone lan are purely IPv4 and should never see IPv6 traffic as such ...
If I remove all ZBF related config, then traffic flows without problem.
R1 config
class-map type inspect match-all cm_icmp
match protocol icmp
policy-map type inspect pm_icmp
class type inspect cm_icmp
inspect (code)

I recently picked up a Catalyst 2960G and am trying to get SNMP management working over IPv6. I have the IP Address set to the local link, and can successfully ping and telnet to the switch (so the network can get traffic to and from the switch). However, SNMP packets just seem to disappear. I am running WireShark on my machine, and I see the packets go out to the proper IP, but nothing comes back. When I check "sho ipv6 traffic", I can see where there are UDP packets that are received, but, again, none going out. Also, when I run "sho snmp", all of the packet counts are 0.
Here are some relavant snipets from my "sho run":
interface Vlan1
no ip address
no ip route-cache
ipv6 enable

Have a v2 E1200. Connect with PPPoE to ISP. IPv4 works fine. With firmware included on router, 2.0.01, it would receive a /64 of IPv6 from the ISP. This /64 would show up under 'status' / 'local network'. Although it did not seem to advertise this space to PC's on my network so I was unable to use it. I updated firmware to 2.0.04. Now it does not even pick up the IPv6 /64 at all.
Anyone have PPPoE and IPv6 working? Anywhere I can download 2.0.01 to try it again?
Is there a model of router that actually works with IPv6?

I have a windows vista computer and my internet works through a modem/router. Just a couple of days ago my internet stopped working but the modem connection would always say its on. I've also noticed that the firewall is off and when I try to turn it on, it won't let me. Also, before the internet stopped working .I uninstalled pc tools *because I already had malwarebytes* but I don't know if that has anything to do with the internet not working. I've already tried the basics.. like putting it on safe mode and changing modems but nothing has worked so far.

my netgear wireless modem model - wgr614 v10. When I connect router to PC via LAN cable the wifi speed on my mobile goes to around 8MBPS and as soon as I disconnect LAN cable from PC it went down to almost 0. In short wifi only working fine when LAN is connected to my PC . I have selected channel 11 and Mode upto 54 MBPS and WPA-PSK key. My region is North America and latest firmware is available on my router. As recommended by some netgear support representative I changed the Fragmentation Length and CTS/RTS Threshold to 2304 but the problem is still there. What I noticed after that is as soon as I remove the LAN cable from my PC the wireless network start showing me no Internet access. And as soon as I insert LAN cable again to my PC wifi start working.
