I decided to try and get my network ready for IPv6. All of my hosts are set up to do stateful autoconfig, I have radvd installed and working, and I can ping6 ipv6.google.com from my Ubuntu server. However, when one of the clients on the inside tries to ping6, no packets return and I get this message in the router's syslog:
Code:
Feb 8 17:55:17 foo kernel: [ 1344.824474] Dead loop on virtual device tun6to4, fix it urgently!
I want to set up a Linux box as a wireless router to replace our existing Netgear WNR1000 router, as I believe the Netgear does not support the coming IPv6 protocol. Unfortunately, it is not flashable with OpenWRT or DD-WRT presently.
As we have Comcast, our cable modem acts as a dumb modem according to the customer support guy I talked to, and our router is the one that asks for the IP address from DHCP. Thus, when Comcast switches over to IPv6, I don't believe my existing router would work, correct?
My idea is to take a Linux box and put two NICs and a wireless adapter in it, using IPCop or Smoothwall to set up a router. I could then enable IPv6 support for when we have IPv6 with Comcast. Is that possible? Would there be a way to get BIND to hand out private IP addresses in the same subnet on the both the LAN NIC and the wireless card?
Anyone who's interested in playing with IPv6 should be able to do so using '6to4' - even if you're behind a NAT device! The following steps works for me on Ubuntu 11.04 (taken[URL].. 1. Make sure the 'iproute' package is installed:
Quote:
$ sudo apt-get install iproute
2. Calculate your 6to4 address:
Quote:
$ ipv4="74.125.237.49"; printf "2002:%02x%02x:%02x%02x::1" `echo $ipv4 | tr "." " "`
2002:4a7d:ed31::1
(Replace 74.125.237.49 with the public IPv4 address assigned to you by your ISP)
[Code]...
The goal: ipv6 connectivity using 6to4 The problem: no connectivity on some internal hosts (mixed win & debian) and no ipv6-web access on any host. Let's start with my external box. It is headless debian lenny dhcp/local-dns & cache/firewall. It has the following interfaces after a reboot:
[Code]...
My understanding is that ipv6 will auto-configure itself and that the radvd file is all that is needed by the external host to give all the ipv6 enabled internal hosts ipv6 web access. My question: How is my external host misconfigured? Or are the problems specific to the internal hosts? I am assuming that I have issues on both the external and internal hosts since some of the internals have golobal ipv6 address and some don't. I do however wish to address the external host first.
I have been struggling to get FC15 to act as an IPv6 router for a while now, am sure I am missing something trivial.. The idea is that I have a ppp / adsl connection (this works fine), use the wireless card on my pc with hostapd and dhcpd to provide connections to other pcs (works fine), and radvd to delegate ipv6 addresses.
The issue seem to be that as soon as I turn on ipv6 forwarding (net.ipv6.conf.all.forwarding =1), the ppp connection no longer gets an IPv6 address. This means the router cannot ping any ipv6 address outside my network.
If I disable ipv6 routing, my router gets an IPv6 address on its ppp connection, and can ping things such as ipv6.google.com just fine, however (of course) no packets are forwarded from my network and radvd complains that forwarding is disabled.
my local clients connected to the IPv6 internet.
I've already designated a machine to act as the router to the hurricane electric tunnel. I created a he-ipv6 device on it and can ping ipv6.google.com. No problem.
The problem happens when I want clients to use that router. That is, I can't ping ipv6.google.com from other machines on my LAN.
I setup /etc/radvd.conf, which seemed to successfully give out addresses to my clients:
interface eth0
{
AdvSendAdvert on;
prefix MY:HEREFIX::/64
[Code]....
I start the daemon and check that my clients have new ip6 addresses. So far so good. On my router, I do a sysctl -p and see that /proc/sys/net/ipv6/conf/all/forwarding = 1. I haven't touched ip6tables/iptables yet. Both are in a flushed state.
My ipv6 router is actually inside the LAN which gets internet from another machine which has let ipv6 packets through using protocol 41. I figure I don't have to worry about anything else because if my router can ping6 ipv6.google.com, the failure point would be there.
So my clients get ip6 addresses, but can't ping6 the router nor the ipv6.google.com. They do resolve ipv6.google.com however and I checked the traffic on the router over he-ipv6 from ifconfig and RX and TX bytes were changing during the ping.
My router has only one physical device for forwarding, eth0 and the tunnel device he-ipv6. Do I need to add some kind of ip6tables to see a simple ping from my clients?
My router doesn't support IPv6. I'm wondering could IPv6 support be provided by just upgrading the firmware? I thought it was just a protocol. Also how does not having IPv6 support affect home users?
View 3 Replies View RelatedI have just installed Kubuntu 9.4 and my wifi will not work. dmesg tell me it is looking for IPv6 and my router does not support it.
how I can tell the OS to ignore IPv6 and use IPv4?
I have read writing alias net-pf-10 off; and alias ipv6 off in /etc/modprobe.d/alias is supposed to work but Kubuntu 9.4 does not have an alias file in modprobe.d
I set up a static IPv6 address and a gateway in /etc/network/interfaces. However, a bad router in my network environment alway send wrong ICMP router discovery messages to me. So I have got extra (wrong) IPv6 address and gateway, and the routing is confused. On Windows Servers, I can use "netsh interface ipv6 set interface "Local Area Connection" routerdiscovery=disable" to disable ICMP router discovery. But I don't know how to disable it on Ubuntu 9.10. How could I disable ICMP router discovery for IPv6?

Setting up a Linux router in Fedora 10. The router has an IP (192.168.1.1) for the eth0 on the internal LAN and a static registered IP for eth1 on the internet connection. All the internal LAN client PCs have gateway set to 192.168.1.1. My question is what do I set the gateway address to on eth0 and eth1 and how would I configure this in /etc/sysconfig/network?

View 1 Replies View RelatedOkay, a few days ago I got a small job setting up a router for a neighbour of mine. He wanted me to set up a wireless network for him. The router he bought is a Linksys Wireless N-Router E1000. I set it up the passwords and everything. Only to find out that I couldn't connect at all to it. The main computer with a direct ethernet connection to the router was the only one that had internet. Everytime I attempt to connect wirelessly with any device, it will take extremely long time to connect, to the point where I will just quit connecting.(Example: 15 minutes of waiting, when the laptop is right next to the router)
Any ideas about what I am doing wrong here? As far as I can think of it might just be a faulty router, because the router will not implement any changes(like setting a password) I set on it. Only wired connections seem to work. the router is called a linksys wirless N-router E1000.
World of Warcraft requires that TCP Ports 1119, 1120 and 3724 are forwarded. The Blizzard Downloader requires that TCP ports 3724, 1119, 4000, 6112, 6113 and 6114 are forwarded. It can also benefit from having ports 6881 through 6999 forwarded. The World of Warcraft Voice Chat feature uses UDP Port 3724.
i use the hotspot feature to play warcraft and i am running ubuntu 10.10 ... i need to forward these ports ... any way to easily download an app to configure the phone like you would a router? its probably easy i just cant find it.
post the "perfect" tutorial for setting up a router and firewall for Ubuntu 10.10 Server 64-bit? I'm kind of a n00b when it comes to Linux, so I get really confused with some things, I have seen things on the ubuntu wiki about this... but it really confuses me =
I'm trying to setup my ubuntu sys as a router and firewall... Internet -> Ubuntu (Router) -> Switch (no DHCP on it) -> Computers I've already setup bind and dhcp3 and got those working perfectly... I've also setup Squid3 and Dansguardian for content filtering (blocking ads and such) and got them working too... I want to set it all up to be transparent, and allow the system itself to function as a powerful firewall router, giving absolutely NO issues to client computers connected, and no speed reduction at all.... I want to setup the firewall to allow all outgoing connections, but block everything incoming (stealth the network)... Forcing all http/s traffic to pass through dansguardian, then to squid...
But am very confused on how to pull this off... The system is running Ubuntu 10.10 Server 64-bit, with 4 GB of RAM, 320 GB SSD, and two 1Gb NIC cards... Sorry if I'm not very clear, I do speak english perfectly, but just kinda new to the "Linux world", I was using SONICWALL but that's getting a little too costly to my network and wanna do a free alternative... Something completely CUSTOM, not using some network security distro.

View 2 Replies View RelatedI have an old pc that I would like to use as a headless server for my music, files, etc that I can access at work and other places outside of my network. I'm a complete noob in this department so please excuse my overwhelming ignorance. The only thing I've managed to succeed at was installing fedora 13. Two things in particular are giving me trouble: 1.)setting up my router and fedora box so that it has a static ip address and 2.)connecting to the fedora box via vncviewer on my laptop.
HERE ARE SOME QUICK SPECS THE DEVICES INVOVLED:
Fedora Box: Intel Pentium 4 2.66GHz, 1GB ram, Fedora 13
Laptop: Toshiba Satellite A505, Intel Core 2 Duo T6600 2.20GHz, 4GB ram, Windows 7 Home Premium 64-bit
Router: D-Link WBR-1310
ISP: Comcast (cable)
HERE'S WHAT I'VE DONE SO FAR:
Setting Static IP
On the fedora 13 box:
1.)Went to Network Connections and added a new connection
2.)Copied mac address from the default connection
3.)On IPv4 tab, added new address: 192.168.0.200 (this is out of the range which my router will assign automatically) netmask 255.255.255.0, set gateway to 198.168.0.1(router's ip on the network)
When I connect to this new connection web pages don't load, etc. but when I'm on the default connection I have no problems.
Connecting With Vnc Viewer
On the fedora 13 box:
1.)System -> Preferences -> Remote Desktop
2.)Under Sharing I checked "Allow other users to view your desktop" and "Allow other users to control your desktop"
3.)Under Security I unchecked "Ask you for confirmation", checked "Require the user to enter this password", and specified a password
On the router
1.)Set up port forwarding for port 5900, TCP only, to the ip address of the fedora box.
On the laptop
1.)Installed VNCViewer
2.)Went to whatsmyip(dot)org to get ip address of router
3.)Tried to connect to that address, port 5900 (ex. ##.##.##.###::5900)
4.)Connection times out everytime.
Setting up desktop (9.04) behind router for remote access by latptop (9.10) I am setting up desktop (9.04) behind router for remote access by latptop (9.10). Rationale: All of my files are on my desktop HD, but I am often out of my home needing to work on my files. It is becoming labour intensive to keep track of the files I make/change and try to copy them on my non-connected desktop/laptop.
Dream: Able to remote access and modify my desktop files from my laptop (while the files remain on the desktop). Request: A simple, GUI, basic, non-technical guide how to set it up!
What I know: 1.I was going to use the 'Remote Desktop' VNC connection under System->Preferences. However, if I understand this correctly, this only secures my computer (i.e. Locks the front door of my desktop) and the data streamed between them is not encrypted.[URL]..
2.Then I need to set up my router to accept the connection from my laptop.
3.Then I will need to use SSH to secure the info sent between them. This is the bit I don't really have a good grip on.

View 9 Replies View RelatedI have three machines say A B and C. I want to make machine B as a router for A and C, so that the ping packets from C to A should be going via B. I have directly connected two interfaces(eth4) of A and B and similarly two interfaces(eth5) of B and C. I have even set up a route between B and C. 1. But I am not able to set a route between B and A.2. If I ping A from eth4 of B(viceversa) it works. When I ping B from eth5 of C it work but not the viceversa.3. Also, if I ping from C to A, B receives the packets, but not A.
View 3 Replies View Relatedi must make this work with the use of virtual pc's. I have vm player and installed fedora ( the latest version ) and one xp . So i have 2 virtual pc's. I'm making it simple for start so i can add more pc's when i see that it is working. I have setup a dhcp server at the fedora virtual pc. The fedora virtual pc is like a soho router. The xp pc is getting ip from dhcp while the fedora one has a static one.
My pc is behind an adsl router. Both virtual pc's can see each other which means i have no connectivity issues.Im trying to setup a squid proxy ( transparent one ) so for example the xp pc can access porn sites and such. I used all required configuration for the squid to work and started the service. Ive also inserted with iptables the commands to forward all incoming port 80 packets to port 3128 ( the squid ). It doesnt seems to be working and i thik i know why but i dont know how to fix it.
Because the xp has a gateway at 192.168.1.1 ( the adsl router ) packets go directly to it and not to the soho router ( fedora virtual pc as i intend to do) What can i do to solve this problem ? How can i forward all packets to go to the fedora virtual pc first and then the fedora pc to forward them (if necessary) to the adsl router? PS. I used Bridged connection on the networking configutration on the vmware player ! If you also want i can post the code for squid or iptables if needed !
