I'm having problems communicating with a remote server, with openvpn. I can link with ssh ok, but the link stalls when viewing any but the smallest texts. I tried reducing the tun0 MTU, though only from 1500 to 1400, but this seemed to have no effect. Before trying a larger reduction, I'd like to clarify two points. Firstly, is it necessary to re-boot the remote machine for the change in

Hello, i have a little question. My system: ip route: 0.0.0.0/1 via 10.8.0.5 dev tun0 default via 192.168.2.1 dev br0 proto static metric 425 10.8.0.1 via 10.8.0.5 dev tun0 10.8.0.5 dev tun0 proto kernel scope link src 10.8.0.6 88.198.140.127 via 192.168.2.1 dev br0 192.168.2.0/24 dev br0 proto kernel scope link src 192.168.2.101 metric 425 192.168.122.0/24 dev virbr0 proto kernel

Hi, I am running OpenVPN where i have one central hub VPN server, and multiple spoke VPN clients. I can ping from each client to the server and each client to computers on the subnet which the server resides (192.168.2.0/24) so it works ok there. I cannot however, ping from one client to another client. I guess the packet path would go: clienta -> vpn -> shorewall/router -> vpn ->

Hi all, I have set up a working OpenVPN2 connection between my Server and my gateway at home. Now I want all traffic to be routed through this VPN connection. Currently everything is going through eth1 to the internet (to the gateway of the University which forwards it to the internet :-). We must use a prox-server and because of this I am not abel to watch the real-Media streams on

I use dyndns's (free) service to access a remote machine with a dynamic IP address. The machine is running under CentOS-6.0. I can ssh into the address given me by dyndns (*.homelinux.com), but when I do this I get the warning "reverse mapping checking getaddrinfo for" * "failed - POSSIBLE BREAK-IN ATTEMPT!" This doesn't really matter, as I normally use OpenVPN for

Hi all, I have succesfully joined together three LANs using OpenVPN over Linux (Debian) gateways at the 'exit' of each one of these LANs. The VPN seems to be OK, as I can ping network hosts from one LAN to another using their private IP addresses with no problem at all. However network browsing through the VPN is not working. The network diagram for my setup is at

Hi! I''m trying to create a routed VPN using OpenVPN - and having trouble with the routing concepts involved. Let me see if I can properly describe my current topology: Server - LAN, with both local workstations and remote bridged workstations on the 192.168.0.0/24 network (this works without reservation). Server located at 192.168.0.71, 192.168.0.72, 192.168.0.222, and few

I'm running an openvpn server on a CentOS machine - that is my excuse for posting my query here - and I'm wondering if there is some way of finding all the clients (not just those connected at this moment) who have been registered as clients of the openvpn server? -- Timothy Murphy e-mail: gayleard /at/ eircom.net School of Mathematics, Trinity College, Dublin 2, Ireland

When using shorewall with a road warrior openvpn setup, how can I get the tun interface to masq through a lan interface? Example Setup: Machine A (tun0 10.0.0.1) -----------VPN---------(tun0 10.0.0.2)---------Machine B(10.10.10.1) When I ping Machine B from Machine B, Machine B is receiving the echo request, but it doesn''t know the route back to the 10.0.0.0/24, and there

Hi, I posted this question yesterday on the Openvpn mailing list, with no response, figured I will ask here too. I have been using openvpn for quite a while, no major problems encountered. Now I need to allow the server to access the lan of the client, and I can not figure out the routing. This is what I have after the tunnel is brought up: SERVER (A.A.A.A) Arx:~# ip addr ... 3: eth1:

How do I insert the iptables rule below using firewalld? I'm moving up from CentOS 6 to 7 on an office gateway and I'm trying to get OpenVPN working to allow home workers to access PCs at the office. I've got it all working but only by manually inserting an ACCEPT rule in the FORWARD iptables chain: iptables -I FORWARD 3 -i tun+ -j ACCEPT This rule was extracted from my iptables

Hello all, We have a few aliased Ethernet addresses on our server and if I do not use the Bind statement in the "Global" section then the NMBD seems to try to bind to all of the addresses. We are actually using OpenVPN which make the connections just fine on a 172.16.x.x subnet to "tun0" device. The problem is that Samba does not seem to find the tun0 device and reports

I'm moving my home network server from a Dell server, which has been having some mysterious problems, to an HP MicroServer. Everything - MySQL, OpenVPN, email (dovecot), httpd, etc - except for openLDAP, which is taking more time than everything else put together. I haven't found any straightforward instructions on this anywhere. The official RedHat document

Dear list, I am having a problem with openvpn. I have the following arrangement, running two instances of openvpn on "home fw". I want to protect my WLAN in back of the home fw and that works fine. I can see "Peer connection initiated with 192.168.1.3:5000" in daemon.log on homefw. Nothing gets initiated with officefw, nor can I ping the other end of the tunnel at officefw.

Hello! I''ve the following set-up RemoteClient1 (Win Vista), RemoteClient2 (Win XP) do both connect to my OpenVPN box. They can talk to each other, using their 172.16.1.x tun0 Address on the server. The server itself (Ubuntu gutsy, OpenVPN: 2.0.9-8, shorewall:3.4.4-1) has 1 NIC that connects the machine to a) a DSL-router (forwards several ports to this linux machine, including the

Friends-- I'm stumped! Cannot get mount.cifs to work over a tun connection. How would you trouble-shoot this? 1. It cannot be openvpn causing the problem: I can ping across the connection both directions on all machines. 2. It cannot be samba causing the problem: I can mount.cifs the smb shares on the lan (using the identical credentials file) without any issue. 3. Have iptables

I have a 1.5TB internal disk on my server. I partitioned this with fdisk, and CentOS-5.6 runs perfectly on it. But fdisk gives a very strange report.
