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 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.
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.
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?

View 4 Replies View Relatedhas 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'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

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.

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 got trouble for this ipv4 & ipv6 fragment trafic prob/attack.how do i prevent it from comming in to my network? is it way to prevent it in cisco router part?
View 2 Replies View RelatedI'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.

View 4 Replies View RelatedI 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.

When I first installed the router I used the built-in provider settings for "ONE" which used to be the name of the provider before it was taken over by orange.at. It seemed to work fine but I experienced some funny server errors with certain web services. I contacted orange.at about this and they told me to adjust the provider settings in the router as follows:
Dial number: *99#
APN: fullspeed
The reason for the problems was that they use different proxy servers for their services and applications. Now it works fine (so far).

My ISP provides IPv6 connectivity in the form of dual stack IPv4/IPv6 with DHCPv6 Prefix Delegation. Using a Cisco IOS-based router I managed to make such a connection by using as a template the Cisco IOS configuration file that my ISP has posted as an example in the following link:
[URL]
The main point on this configuration is a PPPoE connection with:
interface Dialer46
ipv6 address autoconfig default
ipv6 enable
[Code].....
configure this router according the Cisco IOS configuration file I linked on the top in order to have a working IPv6 connection?
Our internet provider has no intention of providing a IPv6 DNS so I have a crippled at best service. We live in an area where our only option is through satellite service, so changing providers in not in the cards, yet.
If I "Disable" the DHCP Sever, the setup menu provides a method for me to force feed up to three Static DNS addresses, all with IPv4 addresses.
There are several locations that provide "free" DNS service, but how does one verify the security of such sites? Does Cisco keep track of the status of this kind of service or am I on my own? Cisco seems to endorse two DDNS services, but for home use, the extra charges seem otherwise unnecessary, and do not yet address the IPv6 question.
The first few that I have investigated that do provide IPv6 service also provide their addresses in IPv6 format. The E4200 menu does not seem to allow me to do that.
Am I going to be forced to live with crippled IPv6? I have already discovered a software product that has failed since changing routers, but works if I take my laptop to a particular WiFi location.
