D-Link DIR-825 :: IpV4 Versus IpV6 Implementation For Remote Access And VPN?
May 16, 2013
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?
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.
Unfortunately I didn't discover any configuration switches concerning an IPv6 firewall! So the important question is: Is there any firewall implemented at all? And if so, does it confirm to RFC6092.
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.
well a couple days of go it was working fine until i updated windows 7 now it says im connected to the internet but when i go on it dosnt load anything, and when i go check it says that "IPv6 connectivity: No Internet access" how ever the IPv4 is connected to the internet, should i restore settings to osmetimes earlier this week
I'm looking to try and implement ipv6 HSRP on a series of IOS-XR Routers running 4.2.1 following on from successfully setting up IPv6 HSRP on a few cat6509s on VLAN Interfaces in other parts of the network. I have entered the "router hsrp" configuration menu and gone into the interface in question that I'm looking to setup with IPv6 HSRP. Unfortunately, there version 2 or address-family ipv6 commands are not available.
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 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 . . . . . . . :
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?
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.
Newly acquired DIR-615 E3 with F/W vers. 5.10. Router configured with IPv4 static address for WAN works fine. As soon as I configure the WAN IPv6 with a static IP address also, the configuration for the IPv4 static IP is corrupted. Other combinations of (WAN config) using static for either IPv4 or IPv6 with DHCP or other seem to work. Just appears to have conflict with two WAN static IP configurations.
The products from SRP 540 series line (541w etc) will ever support IPv6 features or remote VPN (eg SSL VPN or Cisco QuickVPN)? If yes, is there a time horizon?
I have Dell XPS L502X, Windows 7 Home Premium.My internet was working last night but when I turned it on this morning it would not connect.It is connected to my bt homehub with full strength but no internet access. It says IPV4 No Internet Access. I tried using a wire to connect it but that did not work either.Other devices are connecting. So can't be a problem with the internet itself. [code]
I am trying to find an effective way to extend the wireless signal across our home. I have tried various different solutions. Currently, I have an e4200 primary router that is cascaded with two additional e1500 routers that have been configured as access points. The Linksys support team hosted my computer and configured the devices. The e1500 routers are connected via ethernet wires running through the walls. And, this seems to be working well. Here's my question. The e1500 routers are configured with different SSID names, which Linksys advised was required to avoid conflicts in communications from the three router devices. Is there any way to configure this set up or something similar so that the entire wireless network has the same SSID and is seamless. In the current configuration, I have to specifically connect to the primary router or one of the two access points.
I have set up an access point as per the instructions I found on this site. It works perfectly, holds a wireless signal fine. Now, I have the challenge of trying to remote connect to the home computer that is connected to this access point. I have absolutely no clue as to what changes in settings have to be made.
I recently purchased a 825 and a WD Mybook Live. I have been going back and forth on the WD board trying to resolve a remote access issue with the mybook and I am being told to do some settings in the router and I am not sure I have dine them correctly> It has not resolved the issue but I would like to make sure I am correct before I claim its not a good fix. The mybook is connected into a network port on the router which is connected to a High Speed modem and then out to the internet. Initially I was told to enable UPnP on the 825, which was already enabled. Then this is what I was told to do by a WD tech. You could try assigning a static IP to the My Book Live, then making sure ports 80 and 443 are assigned to that IP on your router. It is possible that something else is taking one of these ports. We use uPnP to try to open up these ports, and if it fails, we resort to relay mode. In the future, we will allow you to set these ports within the My Book Live to other than 80 and 443.
I am having trouble accessing my DIR-655 remote management screen via ip to my network.To make sure i didnt have any odd settings, i did a hard reset on my router first.I then enabled remote management, and left the default port 8080 I try to access viw the ip address on my status page suffixed by the port 8080 [URL] page cannot be found.I then enabled https and tried to access via:[URL]page cannot be found.I then setup a entry in the virtual server to redirect http requests to my workstation hosting IIS7, if i connect to localhost, the iis welcome screen appears, but if i browse to my ip, i get nothing.I am using Cox residential service, i called them and they informed me that they do not filter or block requests in any way.
i have a WD My Book Live and it's connected to my DIR-825. i'd like to configure the router to allow FTP access to the NAS from the internet. the drive has an option to enable FTP in it's configuration, but i have not done this before and i don't know what to do to create a solid/secure FTP portal so that i can access my files remotely.how do i configure the router for this ? my router is set to DHCP and i have turned MAC filtering on.. in particular i am looking for the ability to transfer/copy files from the drive, and not allow any modification/writing to the drive from the outside.
I opened the remote management to my Dir 655 but i can't enter it I tried to change port it didn't work, tried to factory defaults or hard reset didn't work what can i do I think it all so stuck my access to my remote desktop (not sure)
And I got 2 internet connections from isp one is static ip leased line and the other one i dsl dynamic ip one.
What I want is i need to configure internet load balance between these 2 internet and also i need to use static ip for remote access vpna and for my exchange port forwarding.
My dsl line in 100 mps and my leased line 2mb dedicated.
I configured the router as with some example config i got on internet my internet is fine but load balancing not happening and i configured the REMOTE ACCESS VPN . I am able to connect the remote access vpn but no communication through remote access . i cannot reach any device through remote access.
Note: if load balancing is not possible how i can configure for internet traffic use dsl line and for remote access vpn and live exchange port forwarding through leased line.
I am attaching my configuration and also debug crypto isakmp status
After I change my router, I recently found out that I cannot access remote network resources after VPN tunnel is established. I use CISCO System VPN client. I can see the connection is successful. I cannot ping server on the remote network
