Cisco Routers :: RV220W And IPv6 Prefix Delegation
Aug 6, 2012
I noticed that the recently released firmware version 1.2.0.9 for the RV110W router mentions in the release notes that DHCPv6 Prefix Delegation is now supported.
Does that mean that this feature will also be implemented in some future firmware release (if we ever see one) for the RV220W router? This is the method used by most if not all ISPs around the world (e.g. Comcast) for IPv6 and the only one RV220W does not currently support. P.S. As of beta version 1.0.4.13 there is no support for IPv6 Prefix Delegation.
I am trying to configure this router to obtain an IPv6 address from my ISP who offers a dual stack IPv4/IPv6 DHCPv6 Prefix Delegation service.
I did a WAN packet capture to see the type of DHCPv6 packets the router sends to the ISP in order to obtain an IPv6 address and I saw that the router is sending DHCPv6 solicitation packets of type IA_NA i.e. for Identity Association for Non-temporary Address. However, most ISPs that offer a dual stack IP4/IPv6 service, they use DHCPv6 Prefix Delegation in which case the router is expected to send DHCPv6 solicitation packets of type IA_PD i.e. for Identity Association for Prefix Delegation.
I then downloaded its configuration file and saw the following:
So, the option for the DHCPv6 client to perform a prefixDelegation request is disabled. Does that mean that if I set this flag to "1" it is going to work? Well, I edited the configuration file and changed this flag but the router refuses to load it! It complains about the file being changed. How does it know that? Is it computing some type of checksum? How can I manually edit this flag and update the router's configuration?
My ISP (OTEnet, Greece) offers IPv6 connectivity in the form of dual-stack IPv4/IPv6 with the requirement that the router supports DHCPv6 Prefix Delegation for establishing an IPv6 connection.Using other routers (Cisco 887W, DrayTek Vigor2130n), I have established an IPv4/IPv6 connection but I am unable to do so with the EA4500. As a matter of fact, when I have the "IPv6 - Automatic" option enabled the router not only cannot obtain an IPv6 prefix from the ISP but it gets stuck in the connection attempt and never obtains an IPv4 or an IPv6 address. I have to disable the IPv6 option in order to simply establish an IPv4-only connection without problems.So, my questions are:
1. Does the latest (2.1.38.38880) firmware support dual-stack IPv6 and DHCPv6 Prefix Delegation?
2. If the router cannot negotiate an IPv6 connection why is it not establishing an IPv4 connection only but gets stuck in the process?
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:

The main point on this configuration is a PPPoE connection with:
Question 1. I have no idea how to route IPv6. My provider has provided me with a subnet. This subnet is for example 1:1:1::/48
The router of the provider is located at 1:1:1::1 and my router should get 1:1:1::2(Cisco router). Every subnet I want to create must be routed by 1:1:1::2, for example if I want to create 1:1:1:1111::/64 it needs to be routerd by 1:1:1::2
How do I configure this on the RV220w?
Question 2. I have the possibility to create vlans on the RV220W. I can configure IPv4 addressen per vlan. Only for IPv6 this is not possible.How do I configure this or when will new software be released to configure this?Or do I have to edit the configuration file?
We have been testing out IPv6 configurations on a 5520 running 8.2(4). We have assigned EUI-64 prefix addresses to sub-interfaces to allow clients to auto-configure there IPv6 IPs and it works correctly. I used ASDM to do the original configuration and noticed that there were two different ways to do it, both of which seem to work. I can add a prefix under the Interface IPv6 Addresses dialog box and check EUI64 or I can add it under the Interface IPv6 Prefixes. But using the two methods yields two different interface configurations:
1. interface GigabitEthernet0/1.40 vlan 40 nameif test
After choosing the option "IPv4 and IPV6 Dual-Stack" in Networking > IPv6 > IP Mode, the router's configuration website is not accessible any more using it's IPv4 address or via remote management (WAN IP). However, all other router services (routing, VPN, etc.) are working fine.
At this moment (firmware 1.0.3.5) the router has no IPv6 firewall and therefore when used in a typical dual stack IPv4/IPv6 network it has no protection regarding IPv6 traffic. Hopefully this will be fixed with a firmware update before the World IPv6 Day on the 6th of June 2012.
Since this router already set up for IPv6 and Dual-Stack traffic, would it be possible to give it the ability to get its IPv6 prefix from the WAN side of the router.
Example:
I have Comcast, and as long as my modem and router support IPv6, with the router also supporting DHCPv6-PD to get the /64 prefix from comcast.
I now have an RV180W so this is not an issue for me, but my father is inheriting the WRVS4400N from me and he is also on Comcast.
BGP prefix list is not updated when other party having new downstream with different AS number.BGP filter has disabled but the prefix list is still not updated.BGP soft reset is performed, but the prefix list is still not updated.BGP prefix list is only updated when the other party having new prefix with the same AS number.Can explain why?
Is there a new software version that supports full ipv6 for wan and lan? What may be the replacement for rv016 that supports full ipv6 and may have a density of 8-16 10/1000 ports?
I enabled dual stack on my rv042g router but its not recieving ipv6 information from my isp. My isp is Time Warner in Milwaukee. They assure me that they are ipv6 ready and assume the problem is on my end. All they want to do is have me connect one computer up to my modem. What good is that when I have a network that needs service. The router needs to be working not just one pc. My ipv4 is working perfectly. It is obtaining all information automaticly.
I have several RV082 routers in production, most of them on IPv4-only access. I want to roll out IPv6 on all these networks and have set up a test environment for this.I did start with a factory-defaulted router with a fixed public IPv4 address. IPv4 network access does work as expected.With the 6to4 option disabled, the RV082's IPv6 routing table contains several entries for local addresses, but not public ones, as expected. When enabling the 6to4 transition function as described in SBKB article #567, three new entries are created: [code]
With the router's diagnostic ping function I can ping the next 6to4 relay on IPv4 (192.88.99.1) and IPv6 (2002:c058:6301::). But I cannot ping that next hop address given as default route (::c058:6301).The RV does advertise routes with the correct 6to4 prefix on the LAN side, and the clients connected to it configure themselves with appropriate addresses. However I was unable to ping any IPv6 both in the 2002::/16 as well as in the 2000::/15 range from any system on the RV's LAN side. When trying to add a static route which routes the 2000:: prefix with prefix length 15 to next hop 2002:c058:6301:: with metric 1, I keep getting the message "Please input IPv6 Address with correct format!"could there something wrong with this default route? How can it be changed? And what is the problem with the route I am trying to add?
When I attempt to save IPv6 Router Advertisement settings, it fails and displays this cryptic message: Addtionally many of the settings in this dialog are not in the PDF manual. Seems odd - like this portion of the Router Configuration is broken.
What are the IPv6 anycast addresses using for?, are they some kind of broadcast? I have a router 2811 I'm configuring ipv6, do I need to use these addresses?
I just spent a number of hours getting a site-to-site VPN tunnel and Cisco Quick Connect client running on my WRVS4400N and RVS400. Turns out the problem was the routers don't route IPv6 properly and it takes precedence over IPv4
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 on my ethernet linux box, that is responsible for IPv6. This box is configured as IPv6 gateway from my network and it also sends RA to the network. All devices on ethernet network can work on IPv6 without problem. Clients, that are connected to WiFi, they just receive the RA from this box -> this packet is sended over WRVS4400N to the wifi network. But all other traffic do not pass the WRVS4400N, so the wifi client is not able to ping the IPv6 gateway. There is no problem on IPv4, there the wifi client is able to communicate with any ethernet device.I have tested WRVS4400N setting "ipv4 only". If I switch on "ipv4 and ipv6", than all devices will get some additional IPv6 adresses and the communication from WiFi client to IPv6 router is not working again. How to configure the WRVS4400N to bridge all IPv6 traffic between WiFi and ethernet?
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.
what exactly is QuickVPN?Is it a IPSec VPN?Is it a PPTP?Is it a SSLVPN?can I resolve my local hostnames? That means, can I configure a lokal DNS Server?
I am trying to setup and configure a VPN on the RV220W that uses IPSEC so I can use the Cisco VPN Client I use at work, I have gone through the user manual 11 or 12 times now but still cannot work it out. I cannot find where on the Rv200W iset up the phase 1 authentication username and password which will then lead me onto the phase 2 stage of asking for a username password to allow me access.
Picked up a pair of RV220W's for a project I'm working on. I have several IP's available, 4 of which are assigned to/in use by a server behind the RV220W. All 4 of these IP's are static external IPs. How I can configure the RV220W so that requests to those 4 IP's get routed to the server.
Prior to purchasing this, I was under the impression what I was trying to do was called one-to-one NAT, but after reading the 'Help' document on the one-to-one NAT page, I don't think this is right. Emphasis added below: Cisco RV220W Wireless-N Network Security Firewall Help FirewallOne-to-One NATOne-to-one NAT is a way to make systems behind a firewall and configured with private IP addresses appear to have public IP addresses.One-to-One-NAT Rule TableThis table lists the list of available One-To-One NAT rules configured by the user. Private Range Begin: start ip address in private (LAN) ip addressPublic Range Begin: start ip address in the public ip address (WAN IP), Public IP Subnet Mask: The Subnet Mask of the public IPRange Length: Range length maps one to one private address to public address up to the given range.Service: This column shows service to be accepted by LAN Host.The actions that can be taken on One-to-One-NAT rules are:(Check Box At First Column Header): Selects all the entries in the table.Add: Opens the One-To-One NAT Configuration page, to add a new entry. Edit: Opens the One-To-One NAT Configuration page, to edit the selected entry.Delete: Deletes the selected entries.
So according to their documentation, the server in question would need to be configured with a private IP. Unfortunately, one of the applications I use is licensed via IP address and my understanding is that I cannot use the software with private/non-routable IP addresses.
Is the RV220W capable of not only securing the line (firewall, access rules, content filtering, port trigering & forwarding etc) but also doing what I was hoping to do (keeping the external IP's on the server, and routing appropriately)?
I'm using a RV220W router, and recently got shifted to a dynamic IP solution.Now, I've got a no-ip.org address, but the update service seems to be on no-ip.com. So, I try to enter mydomain.no-ip.org OR mydomain.no-ip.com in the dynamic dns settings, under Host and Domain Name, but when saving the settings it says
'The hostname specified does not exist in this user account' ,which seems to indicate that it manages to login to the update service but gets a negative reply.Is it possible to use the RV220W with no-ip.org/com?
We have 2 sites connected thru 2 RV220W routers via VPN and most things are working fine. I have noticed however, that any device that has a web interface, i.e. our Sharp Copier and our Freenas server, is inaccessible. The page tries to come up but then I get the Cisco "server is down" page generated by the RV220W.
I can pull up the web interface pages if I use a machine on the local LAN but not on any machine across the VPN. The only commonality I can think of is the RV220W blocking that traffic for some reason..
