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?
View 2 RepliesI 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.
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

View 16 Replies View RelatedI'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

View 19 Replies View RelatedI 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":

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?

View 3 Replies View RelatedTrying to control capacity utilization for guest users connecting to a 2960 switch. No problem for IPv4 users, but IPv6 is giving me fits. What I've found out by trial and error so far implies that there is just enough IPv6 smarts in a WS-C2960-24TT-L running c2960-lanbasek9-mz.150-1.SE to make it impossible to control IPv6 traffic. Blocking IPv6 would be sufficient short term, but MAC filtering on type 0x86DD does not appear to work either. Here are the results I've gotten so far:
What "works":
* Protocol ipv6 or an IPv6 ACL in a class map.
* Using a class map referencing ipv6 protocol or an ipv6 ACL in a policy map.
* IPv4 inbound filters and policing.
* Blocking of IPv4 traffic by a MAC ACL blocking type 0x0800 (IPv4) - note that the docs explicitly state that MAC filters do NOT filter IP traffic, except for on this box on this release they do.
What does not work:
* Applying a policy map referencing a class map referencing protocol ipv6 or an IPv6 ACL to an interface. The service policy is accepted by the parser, but is not inserted into the running configuration.
* "class-default" in a policy map only matches IPv4 traffic, not all other traffic.
* Blocking of IPv6 traffic by a MAC ACL blocking type 0X86DD. No problem applying the access-group to the interface, it just doesn't do anything.
I am aware that this box is not supposed to support IPv6 other than for multicast, but as implemented, this is a hole an abuser could drive a MAC truck through.
My questions:
Is this situation unique to this particular 2960 switch or SW release (I also tried 12.2(58)SE2) or does it afflict all 2960's running LANbase?
Assuming the answers to the first two question are negative, what is the minimum requirement to get working IPv6 policing in an edge switch?

My search on the MIMO event revealed one post about IPv4 and IPv6.

View 6 Replies View RelatedI've had my DIR-615 up for several months, and it's been faultless except for one thing. I have router in front of it and only use the 615 as a switch and AP. My main router provides IPv6 access through a 6to4, using radvd to broadcast to the rest of the network.
Whatever setting I set the 615 to for IPv6, it always sends out a default route. On rare occasion, it'll interfere with the correct route from my main router (whose router preference is set to high, instead of medium). Even in local-only mode, the 615 sends out a default route. It's an E1 with the 5.00NA firmware, which I believe is the latest.
I'd really like to disable the advertisements from the 615 altogether, while keeping L2 IPv6 support on the wireless and all. I picked this router explicitly because many routers don't work with IPv6 over WiFi, but it'd be nice to get it working perfectly. If there aren't any ways to do this, is there a place that I can download the source for the firmware?
I am having a problem which I can't seem to find a way around. I have a DIR-615 E3 that I'm unable to get IPv6 to work properly on.I'm connecting to IPv6 over PPPoE, and I'm unable to change the 'IPv6 LAN Address' to an IP my provider has given me. They've provided a native address in the 2607:: range, however on the router it's stuck at a 6to4 IP which is NOT what they've given me (2002:CEF8:8B79:: IP).
I'm thinking of buying a new router that either has better IPv6 support, or one that supports OpenWRT and working my way through that.
We have some technical issue with IPv6 router configuration[DLINK 655] when we try to connect it with ISP provided static IPv6 connection.

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.
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 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?
