Networking :: VPN And Routing - PC No Longer Visible On Local Network

Aug 26, 2010

I am using Network Manager to connect to a VPN server so that I can access some of the computers on the local network there. When I'm connected, I have two problems: All my internet traffic goes through the VPN. My computer is no longer visible on my local network. I waste a lot of time connecting and disconnecting the VPN. Is there any way I can set up a VPN so that I am still on my local network and only requests to 172.x.x.x go through the VPN. I suspect it can be done with iptables, but all the info about iptables goes WAY over my head.

Networking :: Routing To Internet Through One Network And To Local Ips In Another Network?

Mar 31, 2009

I have two networks. One of them is wired, the other is wireless. The wired has an internet connection and a few other computers connected to it. The wireless network has a few hosts connected to it too, but it has no internet connection. What I've been trying, fruitlessly, to do, is make all connections that are bound to the internet, or my wired network, be routed that way, and all the connections to the hosts of the wireless network go that way.

Here's the setup..

Wired:

192.168.1.0/24 Gateway = 192.168.1.1

Route internet through here

Wireless

192.168.2.0/24 Gateway = 192.168.2.1

If my computer sends a packet to the internet, it should be routed through 192.168.1.1 If I send a packet to one of the local hosts of the wireless network, it should be routed through 192.168.2.1. Here's the routing table I've set up(This is one of many configurations I've tried)

Code:

$ ip route show
192.168.2.1 dev wlan0 scope link
192.168.2.0/24 via 192.168.2.1 dev wlan0 src 192.168.2.4

[code]....

With this, and everything else, I get destination host unreachable when pinging. The strange thing is that, if I unplug my eth cable, reboot and connect to the wireless network, everything is fine and I can access the router and the others. I'm trying to improve my networking skills, as I've had this of setting up a small linux box as a router for quite some time, for the fun of it, but I need to get routing under control before I go ruin my network.

Networking :: Routing Red Hat VM Through Local Physical Box?

May 31, 2011

I've setup an XP VM using Red Hat's KVM. The physical Red Hat box has two NICs, a fiber one in use and active and a CAT-5 one that is disabled and with no wire connected. The physical box has br0 active and bridging on the subnet of 192.168.10.0/24. ip route show also displays for virbr0 192.168.0.0/16 My physical box (192.168.10.228)can ping the virbr0 IP of 192.168.122.1, but not the XP VM of 192.168.122.228

I have played around with Window's route command to try and setup some method for the Windows VM to ping the 192.168.10.0 network, but have not had any luck. I've also messed around with the Red Hat netmask and such to work it from the Linux side. But then, as would be expected, I can't talk to other Linux boxes on the physical network.

Does anyone have any ideas how to get the Windows box to communicate with the Red Hat box and the other Linux systems beyond while keeping the two distinct networks of 192.168.10.0 and 192.168.122.0 leaving them both as Class C (255.255.255.0)? I mentioned the unused CAT-5 NIC thinking perhaps it could operate as an internal router even with no cable attached. That was just a random thought and I have not even explored that.

Ubuntu Networking :: Shared Folders No Longer Visible

Feb 23, 2010

I have two computers in the house that I have shared folders and one has a shared printer. I have a desktop running 9.04 and a laptop running 9.10. The desktop has several shared folders and a shared HP printer. The laptop only has one shared folder. Everything was working fine up until a couple days ago. I went on the laptop to access one of the desktop shared folders, and nothing shows up under "places, network" except windows network.

It no longer shows that the printer is currently shared either, but the funny thing is that I can still print to the desktop from the laptop.I just can't figure out how to access the shared folders.

Networking :: Alternative Routing For Local Process?

Nov 26, 2010

I have a multihomed server, connected on two different ISPs. All default trafic goes to ISP1 via wan1. There is special local processes in my system, what must go through ISP2 via wan2. This processes are make connections to TCP:80.

What did I do:

[root@localhost ~]# ifconfig wan1 10.44.8.252 netmask 255.255.255.0 broadcast 110.44.8.255 up
[root@localhost ~]# ip r r default via 10.44.8.1

[code]....

I see that frames goes out with SRC of wan1... I tried this:

[root@localhost ~]# iptables -t nat -I POSTROUTING -o wan2 -p tcp --dport 80 -j SNAT --to-source 192.168.86.2

and saw:

[root@localhost ~]# telnet 194.87.0.50 80
[root@localhost ~]# tcpdump -i wan2 -nnt port 80
tcpdump: verbose output suppressed, use -v or -vv for full protocol decode

[code]....

The connection did not established... Conntrack does not see it!

Ubuntu Networking :: Ipv6 Router Not Routing To Local LAN?

Mar 6, 2011

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?

Networking :: Port Based Routing For Local Traffic?

May 24, 2009

I have problem with port based routing for local traffic. I can't use trick with iptables -t mangle, ip route table 1, ip rule fwmark table 1 because it works only with forwarded packets. I can't even use patch-o-matic because it's obsolete. And xtables-addons doesn't contain support for "-j ROUTE" yet.

Ubuntu Networking :: Local Company Site Is Invisible / Visible It?

Dec 20, 2010

I have the problem with Ubuntu to access the local site within my company network. This network has access to Internet, but the company's site does not have a public address. It is like "http:e-learning.local". I can access this site from any windows machine, but I can't access it from ubuntu. Only if I use IP address, I can access it. However, I have normal access to other sites on the Internet.

Do you have any suggestion how to solve this problem?

Ubuntu Networking :: Can See All Devices On Local Network And Their Local Ip Addresses

May 16, 2010

I'd like a way to see all of the devices on my local network and what their local IP address is. I recall that I used wireshark to troubleshoot a similar problem a while back, but it doesn't seem to have a way to see all of the devices- only the traffic. (I'd like to do this without having to physically interface with my router if possible, and I am in an encrypted network if that matters)

Ubuntu Networking :: Unable To See Local Web Sites From Local Network

Jun 28, 2011

I have installed a web server on my local network. Everything is well configured and web pages are shown correctly from Internet (outside the local network) using the domain or the public IP.The issue is if I try to see that web pages (using the domain or the public IP) from inside the local network. In that case the router config page (192.168.1.1) is shown instead of the web pages.From inside the local network I'm only able to see the web pages using the internal IP address (192.168.1.XX).

Networking :: IP Routing WirelessLAN And Ethernet In Same Network

Feb 1, 2010

My hardware has two interfaces: a) ethernet - eth0 b) WirelessLAN - eth1.After power on, eth1 gets associated to WirelessLAN access point.

The ethernet interface of Hadrware and test PC is directly connected to Wireless LAN access point through ethernet cable. Hardware is associated to Wireless LAN access point through eth1 interface.Now, when ethernet cable is connected to hardware, I can ping 192.168.254.254 from test PC.When I removed ethernet cable from hardware, I cannot ping 192.168.254.253 from test PC.I think access point should forward the incoming packet from test pc to hardware's eth1 interface wirelessely. Where am I wrong? Is it related to Kernel's routing table? If yes, how to detect removal of ethernet cable from hardware and change routing table dynmically?

Networking :: Iptables Routing Packets On Same Sub-network

Feb 17, 2010

I am running into trouble while trying to set-up a iptables routing policy. I have two machines on the same sub-network (xxx.xxx.153.0). One of the machines is used as a default gw for the other (xxx.xxx.153.250 is a gateway for xxx.xxx.153.142 and xxx.xxx.153.254 is a gw for xxx.xxx.153.250). There is no explanation for why the xxx.xxx.153.250 is in the middle -- xxx.xxx.153.142 can go straight to xxx.xxx.153.254, but is is like that for now.I am trying to find an iptable rule to be executed on the xxx.xxx.153.250 machine to route the packets.

Ubuntu Networking :: Use Local IP Only On Local Network?

May 25, 2010

I've got an Ubuntu server hosting our websites and other various things here in our own home. We recently switched to a router that doesn't support loopback (abomination), so I've set up hosts files on our computers so we can access our own sites when on our home LAN.

However, we often take our laptops as we travel about, and I'm guessing due to the hosts files when we try to access our sites, it'll look on whatever local network we're connected to for our server, which won't work, obviously.

Is there a way to set up something like a hosts file that'll only try to look up the local IP of the server when we're on a specific network (our home one), or have one that tries to look for the local IP first, then proceeds to try and resolve the domain name and use the external IP if the local IP doesn't work?

Ubuntu Networking :: Samba Shares Not Visible On The Network?

Jan 24, 2010

I'm trying to share some folders over the network, but the shared folders are not visible on another computer. This is through double clicking my computer from the Network list in Nautilus. However, I can access the share by typing the full address(<computer name>/<share name>) in "File > Connect to Server...".Since I can't type the address manually from my blu-ray drive, I need to get the shares to show on the network. What is wrong with my settings?

Ubuntu Networking :: Network Not Visible In Dialogue Boxes

Oct 12, 2010

I've set up Samba under Ubuntu for windows SMB file sharing (currently unauthenticated but soon to be backed off against A.D.) This is great within Windows where l folders are available as mounted in all applications but from my Ubuntu desktop and Ubuntu laptops, we can only access network folders and files from the File browsers and bookmarks one finds in the "Places" menu. Our issue is that most (but not all) dialogue boxes don't have any options for viewing non-local files and folders. i.e. when I'm in my web browser and I go to upload a file from our local network file server to an internet location, the "Open" dialogue box cannot see any of our local network locations.

Ubuntu Networking :: Wireless Network Is Visible But Disabled - How To Connect

Jul 23, 2010

I have a weird problem that I can't find the answer for in the forums or docs. I can see the wireless network in Network Manager, but it is grayed-out and inaccessible. Other wireless networks are white and I can click on them and connect to them (or could if I knew the password).

My work computer, an IBM ThinkPad T43 running Win 7, connects.
My personal computer, a Dell Latitude C640 running Ubuntu 10.04, sees the network as grayed-out and therefore I have no option to connect to it.

I have tried the following:Checked for hardware drivers - the system says "No proprietary drivers are in use on this system"
Verified that the network security settings are the same on both my work and personal computers: WPA2-Personal
Why can I see the network but it is disabled/grayed-out?

Networking :: Creating Simultaneous Network Connections To A VPN And Local Area Network?

May 31, 2010

I'm working with a Ubuntu 10.04 LTS system with two network interfaces (both Ethernet). I wish to setup this system such that it is simultaneously connected to my local and an OpenVPN network and able direct traffic between the connections depending on what program is sending the traffic. The problem: Under my current OpenVPN configuration all network traffic is directed to the VPN.

My OpenVPN config file (some details omitted)

--remote [gateway ip] # vpn12 load:
--remote [gateway ip] # vpn11 load:
--remote [gateway ip] # vpn15 load:
--remote [gateway ip] # vpn16 load:

[code]....

In practice, I would like OpenVPN to operate out of one of my two network interfaces and leave the other interface connected to the local network. Then by default all network traffic should be directed to my local network unless I specify (on a per program bases) that certain traffic should go though the VPN. These two network connections can (should) stay completely independent of each other and do not need to talk to each other.
