It would be nice to keep this running and automatically connect to the office at all times.Once started, it does this anyway. The problem lies when the user comes into the office. Openvpn connects as usual to the vpn gateway, but this causes weird routing loops.Is there a way to say to Openvpn "Always connect to the gateway unless you are on network 10.10.10.0/24" ?
View 2 Replies View RelatedI have a network that consists of a few desktop machines, laptops, and two Internet connected linux servers. The Linux servers are the gateways, routers, and firewalls for my desktop and laptop machines.Whenever I'm away from home; I can connect to my home machines over the Internet by first ssh'ng (technically I use Webmin; because my firewall on each Linux servers blocks ssh from the Internet.) to one of the linux servers and then ssh'ng to the desired machine on my home network.
This works fine for my home linux machines. But not my Windows machines.I'd like to be able to rdp or rdesktop to my Windows machines.Will OpenVPN allow me to accomplish this ?
I'm trying to connect OpenVPN server using shell command.
I've installed all needed packages (I guess)

i have added a vpn connection on my Lucid desktop machine, but every time i try and connect, it fails. I also have the same, identical vpn connection on my karmic install on my laptop. everything works perfectly on Karmic, but Lucid is having problems. I have followed identical steps for creating the vpn connection on both machines: vpn connections can be made in 2 ways, the first is through the network manager, but trying to connect through the nm-applet returns an error about vpn failing to connect and "no valid vpn secrets".
I suspect this is at the root of the problem. The only way for my Lucid machine to successfully connect through the command line is if I run the openvpn command under sudo.
I have setup an OpenVPN server on Ubuntu server. I am able to connect with Windows clients. I am, however, unable to correctly connect using Ubuntu.
If the router firewall is blocking the pings to keep the connection alive, then the connection initially does not work, but will work after the first timeout and reconnect. If the firewall does not block the pings then the initial connection attempt never times and therefore the connection does not work.
Attached is the readout from the client.
The first attempt gives error ERROR: Linux route add command failed: external program exited with error status: 7
Successive attempts work, they just time out every two minutes.
I've been the las 4 days setting up my first VPN (OpenVPN bridged). The server is up and running OK but when I try to connect I've got this message in the client log.

I successfully installed openvpn and networkmanager openvpn plugin. Then I successfully added a PPTP vpn connection by networkmanager vpn tab which name is "vpn1". But now I don't know how to connect to this PPTP vpn connection. I tried bellow command but no luck.
openvpn --config vpn1.config
I try to connect to my server (whose IP is x.x.x.x below) from my laptop. I have no idea why openvpn client won't work this time. It works fine in win7 before. I re-installed openvpn but it doesn't work neither. Then I searched for this issue, find that it is possibly caused by disabled DHCP Client service. I checked, and found it was enabled. Still won't work after restarting dhcp client service.
Basic Info:
OS: Windows 7
OpenVPN client: openvpn-2.2.0
DHCP Client Service started.
The following is the log during connecting:

I have the following problem:I have to networks in remote places.I have an opnvpn client in one network that connects to the the router (openvpn server).My question is,can i connect the network where the openvpn client is,throught the computer with the client to the other network.If yes,how? (please make it an idiot proof anwser because i have limited knowledge about iptables). I was thinking like forwarding (the router in the network with the openvpn client is also firewalling with iptables) the request of the ip class of the openvpn network to the computer with the client,which masquarades the interface

I'm trying to setup OpenVPN in order to connect back to my home network while traveling for secure browsing and such. However, before I can even start trying to set that up I tried to see if I could open port check my computer through the net. And I'm having a hard time doing that.
As far as I can tell, here are my roadblocks:
1. Is ISP (Qwest) blocking my ports?
2. Is my modem doing the proper port forwarding and firewall?
3. Is my router doing the same?
4. Is my firewall on the computer allowing the request?
To minimize sources of error, I've turned off my local and router firewall and setup my router to forward ports. I'm not to familiar with my modem, but I'm pretty sure that the firewall is turned off by default and I think I've done port-forwarding correctly. But still no success when doing an open port check. At this point I don't know how to diagnose the problem.
i have installed openvpn and config it for a tunnel. my server.conf and client,conf is as follow:
server.conf
port 1194
proto udp

i've set up an openvpn server (with dhcp running on it) and i have to create compatible clients.the problem is how to get an ip by dhcp.with ubuntu i made a script like this
/sbin/ifconfig tap0 up
/sbin/dhclient -e tap0
and everything works fine:tap0 goes up and then start a dhcp request to the server on tap0with fedora there is a nice problem i've noticed that is impossible to run dhclient later on a new interface because i receive this error "dhclient is already running".the tap0 goes up normally but i receive this error when i attempt to get an ip.is there a simple way to get an ip?if i try to kill or restart dhclient when the vpn tunnel is up,all'interfaces lost theirs ip and network goes down crashing my vpn...
Is there anyway you can configure either OpenVPN client or the system to allow connections using OpenVPN to be made to computers on the OpenVPN network using their alias rather than their IP address. This may sound blasphemous but you can in Windows. That is if the VPN network is say 10.x.0.x I could connect to Comp4 or Comp2 using Comp4 or Comp2 not 10.x.0. 4 or 10.x.0.2 or whatever IP is allocated by the OpenVPN server. If the OpenVPN server has not been restarted then it will usually allocate the same IP every time the same client connects.
View 8 Replies View RelatedThis is the first one of probably many posts as I am new to Fedora having lots of questions. This one is about the openvpn client which is used by me to connect to my company network. Thanks to the Fedora FAQ it was easy for me to set up the client and establish a connection. There is just one problem every time I open a connection I am disconnected from my local Internet. I was using openvpn on my Windows XP PC before and there was no problem keeping two Network connections, the (W)LAN and the vpn tunnel. Does anyone know how to solve this? I am utilizing the latest Fedora 11 release and configured openvpn client via the Network Manager GUI.
View 2 Replies View RelatedI have (seemingly regretfully) finally upgraded my Fedora Core 7 linux machine that has served me so well for the past decade. One of the final pieces to put in place was my Openvpn config (which was running flawlessly on my FC7) which I cannot get to work.
Here are my steps.
1. Disabled SELinux
2. Added the following entry in my iptables: (although I've stopped iptables to help troubleshoot)
-A INPUT -i tap0 -j ACCEPT
-A INPUT -i br0 -j ACCEPT
-A FORWARD -i br0 -j ACCEPT
3. Yum installed openvpn and bridge-utils (btw I'm using bridging)
4. Configured my bridge-start script as such:
#!/bin/bash
# Set up Ethernet bridge on Linux
# Requires: bridge-utils
# Define Bridge Interface
br="br0" .....
5. Configured my openvpn server conf as such:
proto tcp-server
port 5990
dev tap0 .....
When I execute my bridge-start script it creates the br0 and tap0 then all connectivity vanishes (I can only ping my gateway 10.0.0.50) - internet and any other addresses time out.
I've recently installed OpenVPN on my dedicated server (Fedora) in order to have full internet access for all of my WinXP clients. In case somebody is interested in the details of the OpenVPN installation, I followed this documentation: Rootserver-as-OpenVPN-Gateway. The installation runs quire nicely, I'm able to surf the net and even file-sharing programs work on the XP clients - at least to some extent. There is a slight problem though: the file-sharing programs complain that they have a "NAT problem" or that they are "Firewalled".
Most likely, this problem can be addressed by configuring remote port forwarding (RPF) on the server. The only routing rules which I've added on the server during the OpenVPN installation are these:
Code:
# initialize natting for openvpn
iptables -t nat -F POSTROUTING
echo 1 > /proc/sys/net/ipv4/ip_forward
iptables -t nat -A POSTROUTING -o eth0 -s 10.66.66.0/24 -j MASQUERADE
Let's assume a certain application on a client is listening on e.g. port 1234. How do I configure RPF for this port on the server side.
This was working and stable on f-10 and f-11. Fresh f-12 install including openvpn, Copied /etc/openvpn/* to new system as root from working f-11 syatem. /etc/init.d/openvpn start (and stop) works as advertised HOWEVER when set to start at boot using chkconfig or Services Configuration program, openvpn does not start. I must manually start it every time. When started, it does work without error messages in the log.
I tried removing the NetworkManager-vpn module with no effect. Thought it could somehow be overriding the auto startup of openvpn at boot.
I'm using Fedora Core 11 and the client OpenVPN on the network-manager into a segmented infrastructure. It works well.
My laptop is on a dmz wireless Zone 192.168.3.0/24 and access Internet through a firewall via a front-end zone 192.168.65.0/24 with wlan0 interface.
But my laptop can access on a back-end zone 192.168.2.0.24 to a server.
When I start the OpenVPN tunnel, I cannot access on my back-end zone because the kernel routing table is modified (all the traffic is routed through the tun vpn interface)
If I define a static route like route add -host 192.168.2.x gw 192.168.3.2 where x is my file serveur, I cannot connect to this server because the routing is make through the tun interface and not by the wlan0 who can access on is gateway
I want to know where changing the kernel routing table file to access on the Internet and on my back-end zone in a same time.
I have a problem with the Fedora 12 Network Manager - OpenVPN configuration. If I use the same configuration and manually start openvpn (as client) I get connected to the OpenVPN server and I can ping the network that I am accessing. With Network Manager - I get connected but when I try to ping is giving me "Destination host unreachable". The routing table looks similar except that when connecting with network manager is giving me on more route in table

Where xxx.xxx.xxx.xxx is the IP of the OpenVPN server. When connecting "manually" I this routing table

What I do wrong in Network Manager? If I try to delete the route with xxx.xxx.xxx.xxx is disconnecting the vpn connection.
I try to establish basic connection between my 2 end systems using openvpn. The problem is when i move the client files to my laptop i cant even ping the server from there. I copy paste the server commands in section 4 [URL] ....
In the client i ran the first command and changing VPNSERVER IP with 10.9.8.1 and LOCALGATEWAY IP with 192.168.1.1
which i thought that whats the server use : ROUTE_GATEWAY 192.168.1.1/255.255.255.0 in the server initialization process
The second command produce error device tun0 not found and when i create one using openvpn --mktun --dev tun
I get RTNETLINK answers : network is unreachable
Note : I use wireless connection in the client system (laptop). The server works good and i could ping him ( from the same machine ) but cant ping him or access the vpn server in my laptop. I also use default openvpn settings...
I have installed an OpenVPN server on my OpenWrt 10.03 router [freshly flashed]:
[URL]
It seems "ok".
I connect my pc to the lan port of the router, and i want to try it out. I'm using Fedora 14 with GNOME. In the NetworkManager applet i set these things: this and this. Ok!. i try to connect, but it fails. Here are the logs: [URL]
one important thing: my routers [the one with the openvpn server] ip address is 192.168.1.2, and i didn't had to write it nowhere. so how could the networkmanager applet know the ip address of my openvpn server? i think this is the problem, but i just can't find where to write 192.168.1.2
p.s.: yes, i tried to google for: "No server certificate verification method has been enabled." but i didn't find a thing, and i'm trying for hours now... :
p.s.: if i [on the router]:
iptables -P INPUT ACCEPT

I ran the Kvpnc wizard and imported my config file and when I try to connect it always says connection timed out.I can connect to OpenVPN without a problem using the terminal, all I can say is kvpnc is a real pain and I don't get why I can't connect with it if I can connect without a problem from the terminal.I thought this was suppose to be a simple GUI that you just imported your config add in your cert and the cert path and that's all.

I'm trying to set up a VPN connection between our CentOS 5.3 server at work and my bosses XP computer at home. At this point, we are kinda locked into Quickbooks. I'm testing the connection from my XP boot at home to see if it works. I can log into our servicemanuals easily enough from XP at home however, the windows takes forever to update. I have the Samba server only listening on port 445 because is seems to work more efficiently at work. I connect to the Samba shares via linux from home and everything works well but, when I try to do anything with the shares from Windows client at home, it's very slow!
I'm thinking that it must have something either to do with the Windows OpenVPN client or the client.conf file. Is there anything I should look at in the .conf file for answers?
Right now I have a machine set up running Fedora. I have configured inittab to accept Console Logins, but I am having problems getting my netbook running PuTTY to connect. How would I go about finding the Host Name and Port to connect to?
View 6 Replies View RelatedI want to configure a VPN over the Internet.I installed the 'openvpn' package, generated the key file, transfered it by a secure way to the client, and setted up the configuration file.
So, in that configuration file I input the IP addresses of the tunneled interfaces. Both IPs are static in the tunnel.
Then, I've heard somewhere that I can assign a dynamic configuration IP for the client. I do this registering a range.
Well, when I tried to change static IP to dynamic IP (changing '192.168.0.2' to '192.168.0.0/24') in the configuration file, the OpenVPN didn't work.
Obviously I don't know what I'm doing, and I really, don't believe that simply changing the IP will make it work, but I tried.
I hope I explained my problem as well.
My configuration file:
# OpenVPN Server Configuration File
dev tun 0
ifconfig 192.168.0.1 192.168.0.2
cd /etc/openvpn
secret key_file
In client I execute the 'openvpn' without the '--daemon' parameter.Then I want that my client uses a IP in a range (192.168.0.0/24, for example), instead of a static IP (192.168.0.2).I also thought to use a DHCP server, but I'm not sure that will work.
