D-Link DIR-825 :: Firmware 2.05NA - How To Get IPv6 In IPv4 Tunnel Working
Jun 9, 2011
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.

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..

I hope that we can get this DIR-825 back from the dead. I did the first portion of the 2.05NA upgrade while wired into LAN1 on the unit, after the reboot the power light went Amber and the unit would no longer respond to pings. I have searched around for various reset methods but have not been able to find a guide or a definitive current D-Link tech manual on how to fix a bad flash. I have tried pinging/arping/web browsing its default IP and the IP I had it set to to no avail.

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 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?

I'm in process of purchasing a new Cisco routers for our branches that will be used primary to enable IPSec virtual tunnel interfce with "tunnel mode ipsec ipv4". does the default IOS IP Base supports this feature? or i need to purchase DATA license or SECURITY license?

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:
Windows IP Configuration
Host Name . . . . . . . . . . . . : M-PC
Primary Dns Suffix . . . . . . . :
[Code].....

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.

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.

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 tried to upgrade to 2.05NA several times and there always ends up being an issue that support is too sad to give the correct answer to and just puts a consumer thru "jumping thru hoops" and getting nowhere.2.05NA (actually started with 2.03NA) first caused a problem with limiting my upload speed to 1024mb. I happened across the fix on another forum and tried it and it worked. It was the default QoS setting D-Link changed after version 2.02NA and refuses to release a new firmware to fix this for everyone. Why they don't release a new FW that fixes the issue but keeps things promised on the package working is beyond me. Now, I purchased a D-Link DNS-323 and I finally got drives to fill it some time back. If 2.05NA is loaded, the Easy Search Utility will not connect to the NAS. I have tried the version the NAS came with AND the latest version offered. It will see the NAS upon 1st launch of the latest Easy Search Utility, but it will not connect and then it disappears if you relaunch the utility and won't return until a reboot. Bottom Line: it will not connect with 2.05NA loaded. It works fine with 2.02NA.
What is the setting that D-Link has screwed over here also that is causing this problem? It is pretty sad that their own hardware items won't play well together unless you run old FW. What setting D-Link changed that is making the D-Link DIR-825 not connect to the D-Link DNS-323 NAS when the DIR-825 has 2.05NA loaded. I have a DIR-825 Rev. B1 and a DNS-323 NAS with its latest firmware. I am using 2.02NA on the router since that is the only one that works and is the latest stable release(other than the DHCP reserve issue), no matter what D-Link wants to try to make people think. I won't try their support since they NEVER did give me the fix for the QoS upload issue and when I asked them to put it as a sticky in this forum when I found the answer somewhere else....well, there is no sticky as we all know. I would like to be able to have the DHCP Reserve issue working too, but I would like to connect to my NAS more at this point.

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.

After upgrading firmware from ver 4.00 to 4.11 I can't watch IPTV anymore with VLC. With version 4.00 IPTV works over router (wireless or cable) fine but because of some disconecting trouble I upgraded to ver 4.11. Setup is the same as it was in ver 4.00 including Multicast parameter.

My DIR-655 stopped working after updating firmware to 3.35. Only power light comes on. port4 flashes for a microsecond when I plug it in. Recovery mode has not done anything. Computer acts like nothing is connected through Ethernet, says "No Cable Connected." Only power light stays on the whole time. I am guessing this thing is broken now. when i go through ipconfig, "no media connected." If not whats a good router under a hundred bucks today, had this router since early 2007.

I've finally got my 3560 switch IPv6 capable (IP Services IOS), but I've stumbled upon something strange: I can configure a tunnel interface, but I can't put the tunnel in ipv6ip mode. The command is missing. I can choose GRE, IP in IP, and a bunch of other things, but no ipv6ip. I'm a bit desperate here and probably I am going to have to live with it, but just in case? I need the IPv6 tunnel for an uplink to a tunnel broker which only supports this type of tunnel, and I'm surprised this is missing.

So I have a Cisco PIX 506e that I've modified a bit, but am quite happy w/ when it comes to performance and configuration (I can actually set up the VPN server w/o too much thought.) I also have a Mikrotik Routerboard 750, I'm no longer using it as my router due to a few config issues I had plus the fact I had to hard code my internet gateway's arp address into the device due to some issues.
What I am wanting to do, which I'm sure is possible and easily accomplished (I just don't have the time right now to try it) is set the routerboard up behind my pix and have it function as an ipv6 router, while the pix handles my ipv4 duties. I've already set up the routerboard w/ an ipv6 tunnel broker when I had it running as my router, I am just curious if it will work in a similar fashion when configured behind an ipv4 device.
