Linksys Wireless Router :: EA4500 - Translate Ipv4 Address And Port To Ipv6?

Nov 9, 2012

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.

Linksys Wireless Router :: EA4500 Loses IPv4 And IPv6 Information?

Dec 21, 2012

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.

Linksys Wireless Router :: EA4500 - Computer Would Not Get Valid IPv6 On LAN

Apr 18, 2013

Lets get this straight, right off!  If I plugged my computer directly to my Comcast Modem, IPv6 works fine on the { url }  So I do not think any of this problem is related to my computer
I bought a EA4500 Router so I would be ready for IPv6, and also wanted N as well as the storage USB port.  When I got the router, it came I guess with the original release firmware.  It looked "Classic", but the box said Smart.  I did the firmware upgrade.  I could not get a IPv6 from Comcast.  IPv4 worked fine.
I then changed to the latest "Classic: firmware, and all started to work.  So I decided to try Smart again.  Same thing, no IPv6 from Comcast.  After being on chat for I think close to 2 hours today and getting no where, I did a reset to start at scratch again.  I then got a IPv6 from Comcast.  Many moons ago, it was a real hassle to switch devices hooked to a cable modem.  At least here you had to power cycle the modem, so I have always cloned my wired Desktop MAC. So when I put it back in, I lost IPv6 from Comcast.  Turned off MAC cloning, and I got the IPv6 again.  So it looks like there is a bug in the Smart Firmware and MAC cloning since it worked OK with Classic firmware.  OK, I could live with no cloning since the issues of yesteryear don't seem to be there in getting a IP from the cable modem. 
Then for what ever reason, my computer would not get a valid IPv6 on the LAN from the router.  I got some IP, but no Gateway.  I tried everything I could think off.  And again, plugging the computer directly to the cable modem, IPv6 worked fine.  So something is just not right with this router as far as I am concerned.
Also, it seems like navigating through the menus on a local connection (, I constantly got a message to wait popping up on the screen, for many seconds.  If I had no Internet connection it would take forever on some things.
I have spent many hours on this, and am just giving up and going to look at another brand product.  I don't need or want the "Smart" functions anyway.

Linksys Wireless Router :: EA4500 Prefix Delegation For Establishing An IPv6 Connection

Aug 30, 2012

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 ( 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?

Can't Assign An IPv4 Address To A Port

Aug 15, 2012

I understand you can't assign an IPv4 Address to a "port". But here's my issue. I have two network cables attached to a managed switch, the location of the two cables are very important. Two computers attached to the said cables.I would like to communicate with one of the computers on PORT 1 and PORT 2, regardless of what computer is plugged into them. They get there IP's via DHCP, and a static IP wont work - as the computer plugged into PORT 1 or 2 may be different.So. I have two ports on the switch that I always want to communicate with the computer on the other end. But I don't (will not) always know the IP address of the computer(s) connected.

Linksys Wireless Router :: DVR8-4000 IPv6 Static Address

Apr 10, 2013

I have a Swann Communication security camera system with their DVR8-4000 hooked to an IPv4 router, connected to the Internet using the new HughesNet Gen4 service. The Swann DVR wired to my router requires a static IP address.  HughesNet Gen4 is implemented with IPv6 and I am told that it does not accommodate an IPv4 type static address.
I have discussed the issue with both company’s technical support.  HughesNet Gen4 reps recognize the issue and may support static addressing in the future, but not now.  Swann reps will not modify their implementation because of the relatively small Gen4 market.  The Swann rep suggested that replacing my IPv4 router with an IPv6 router might resolve the “static IP address” issue.I am looking at several Linksys IPv6 routers including the EA4500 SMART WiFi Wireless Router N900, but know too little about IPv4, IPv6 and router/static addressing to proceed unassisted.
1) can I implement a static address with an Linksys IPv6 router cdonnected to Gen4?  

2) Which Linksys routers offer IPv6 support? 

3) How does one go about setting an IPv6 static address using HughesNet Gen4 on a Linksys router?

Linksys Wireless Router :: Wireless Clients Not Getting IPv6 Address (EA2700)

Nov 9, 2012

I set up the IPv6 on EA2700 (running firmware v1.1.39), and all the wired clients can get an IPv6 address, assigned by the router, without issue.However, all the wireless clients seem to unable to get an IPv6 address. If I connect a laptop to the router both wirelessly and with an ethernet cable, then the ethernet NIC gets an IPv6 IP but not the wireless NIC.

Linksys Wireless Router :: EA4500 - Assign A DNS Address For A DHP Reservation?

Dec 21, 2012

On my EA4500 i've given my Sony Google TV Box (connected by wifi N) a static ip address under "DHCP Reservations". However is there any way to add a DNS server address to this reserved IP so that only the Google Box is affected by the DNS, all the other connected devices remain unaffected? Presently i enter the required DNS address in the google box but i would prefer to do it on the EA4500. I'm using the latest Cisco Cloud fw on my router.

Linksys Wireless Router :: Setting Default IP Address For EA4500?

Aug 27, 2012

I have bought EA4500 router recently in preparations for the Singapore fibre broadband upgrade.
But for the time being I'm using it to connect to my current Linksys WAG200G ADSL Wireless Gateway.
Here's the issue I'm currently facing. I have set my EA4500 router default IP address to to aviod conflicts with my gateway which is using But everytime when I connect my router to the gateway, the router's default IP address changes to or some other random IP address by itself whenever I try to change to back. However, I'm still able to surf the internet and stuffs with that current settings.
Is there something that I could do to prevent the IP address from changing by itself? And will the same thing happen again when I upgrade to fibre broadband?

DNS Not Working IPV4 IPV6 Not Connected?

has quite frankly gotten me absolutely annoyed . I've tried just about everything, from using the netsh commands to changing the dns to 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

Linksys Wireless Router :: EA4500 Off / On And Internet Port Came Back On With 1Gb

May 26, 2012

I have a CISCO modem from SHAW set as bridge. I recently bought a CISCO EA4500 which got automatically upgrade to the current Firmware 2.0.37 after connecting it to my ISP. After a few days I noticed my internet speed was slow. When I checked the router I saw it flipped from 1Gb to 100Mb. Called Shaw they could not figure this one out, while waiting I decided to turn everything off / on and internet port came back to 1Gb. 2 days later same thing again, I just turned off both the modem and EA500 router.  A couple of days later again same problem but this time I just turned EA4500 off/on and internet port came back on with 1Gb.Otherwise I will have to turn this one back in to the store for an exchange.

Linksys Wireless Router :: EA4500 Maximum Number Of Port Forwards

Apr 19, 2012

Background: currently have a WRT320N, thinking of upgrading to an EA4500 assuming ONE feature has been improved: Port Forwarding.
Scenario: Currently I have a WRT320N router, and while it "does everything we need" it has one limitation that is now getting in the way: limitation on number of forwardable ports.  In the port forwarding panel, it has 15 total rows: the first five rows can be enabled for specificaly named services (SMTP, FTP, etc).  The last 10 rows are fully customizable in that we can set the name, ports and protocol. 
The problem is that of the 13 total ports I currently need to forward, only ONE of them is listed in that fixed list.  So, sadly, I can only use one of those first five rows.  I've now filled the remaining ten custom rows, and still have need for two additional ports (for now, may need more down the road).
Trying to get creative, I figured maybe I could just spill over to the Port Range Forwarding page and add a row or two there.  The only problem: it's buggy.  I've found that if the Single Port Forwarding list is filled, then the Port Forwarding Range entries don't work properly.  For example, if I wanted ports 12345 and 12346 forwarded to, they work fine with two single port forwarding entries.  However, if I delete those, add two other port lines I need forwarded (the single list being full again), and add a port forwarding range 12345..12346, they don't work properly, ports just are closed. Only the singles work, the ranges don't.
Question: Has the EA4500 resolved this issue and allow for either more lines (i.e. 20 customizable entries instead of 10), or, better, does it just have an [Add Entry] button to allow for additional rows to be created?  In today's day and age, where one single device (such as an Xbox) can take four rows, a 10-row limit is pretty sparse.  Comparing it to some competitors, for example the D-Link DIR-825 (aging, but still great) allows you to add as many as you want.
I realize "expensive" firewalls like SonicWall's have virtually unlimited customization, but I don't need many of the additional features and don't want to spend $350 on a "high-end" firewall to solve the problem of needing two more ports open.

Linksys Wireless Router :: EA4500 Internet Port Cycles On And Off Every Few Seconds

Oct 22, 2012

I bought a EA4500 to replace my old WRT54G earlier this year. At first the router worked fine. After the automatic firmware upgrade to Cisco Connect Cloud, I was never able to get the Connect Cloud stuff to work, constant 500 Internal Server errors when trying to access the router with the Internet cable attached.  So I downgraded back to the old firmware and all was well again.Then I started having problems a few months ago, when I would wake up in the morning, the router would be cycling the Internet port on and off.I could usually reboot everything and it would work the rest of the day.I lived with it like this a while, and support couldn't seem to find anything wrong.Eventually it started getting worse, until the point I could hardly ever get it to stay connected.I got Cisco to RA the old router and I figured problem solved. Now while the EA4500 was gone, I used my WRT54G again, and everything worked fine for nearly two weeks while I was waiting on the replacement EA4500.

So today the new EA4500 showed up, I connected and configured it, and it worked for a short time.Then suddenly I lost Internet, looked up at the modem and the LAN light was going on and off every few seconds. So I'm back in the same boat as before.I've tried changing cables, same setup works fine with the WRT54G. Modem works fine with WRT54G and connected directly to the computer, zero problems.I tried lowering the MTU, turning on MAC address cloning, and various other things.My modem is a HughesNet HN9000.

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?

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  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.

Cisco Firewall :: 3545 IPv6 Tunneling Through IPv4 - Blockage

Nov 3, 2009

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.
