Firstly: understand the difference between tun and tap. You must use the *same* on both ends, tun for routed vpn, tap for bridged. decide whether you want routed or bridged and set up accordingly. Info on openvpn.net on which is bbest, routed is more scalable and there are tricks to hand out a default gateway on a bridged setup. these tricks may or may not work with Windows openvpn client see faq files. I'd set up dev tun on both ends and make sure you can see the other end of your tunnel. Best to make connectivity work before you mess with default routes etc. Is it worth noting here that you are probably violating policy by punching holes through a firewall? be aware in case admin comes down on you.

* Re: openvpn configuration ` Tyler Littlefield @ ` Kerry Hoath ` Tyler Littlefield 0 siblings, 1 reply; 11+ messages in thread From: Kerry Hoath @ UTC (permalink / raw) To: Speakup is a screen review system for Linux. With a static key there is one client and one server, openvpn can not handle more than one client per instance. You'd need to launch one instance of openvpn for each client connecting on a different port. ip addresses must be outside your network for the vpn; if using a routed vpn. If using a bridge i'd assume you have bridged tap0 on your server to an ethernet interface on your subnet as described in the bridging mini-howto on the openvpn site. If you intend to bridge; handing out a default gateway to your client pc isn't trivial. Perhaps you should consider getting your hands on the building vpn networks with openvpn from pakt publishing book it is easy to follow. Also specifying what you exactly want to achieve in terms of vpns and networks might allow people to give you more directed help. I'm personally not debugging your config files but someone else might be more kind; it's hints only. You must have either dev tap or dev tun on *both* ends of the connection, you can not mix and match. tun is routed, vpn ips outside your subnet with apropriate routing. dev tap is bridge, bridge the tap0 and eth0 interfaces making sure you openvpn mktun the tap0 interface first.

* Re: openvpn configuration ` Tyler Littlefield @ ` Kerry Hoath 0 siblings, 0 replies; 11+ messages in thread From: Kerry Hoath @ UTC (permalink / raw) To: Speakup is a screen review system for Linux. Here is a quick summary of vpns, you will really need to go read the howto if you're serious about getting this to work. It is far from trivial and the time you spend setting this up might not be worth the effort. Have you considered hamachi www.hamachi .cc I know the free services have security problems but might do what you want. openvpn: accessing the internet from remote pcs using home net connection, This is possibly far more complex than you think... A vpn is a virtual private network. A virtual private network is using the internet to carry secure trafic from one machine or subnet to another over a virtual connection. This is virtual in the sense that the network adapter on each end of the vpn does not physically exist, it is a software construct. Regardless of this you need to decide how you want to handle trafic as far as routing and the like. Let us work an example. We have a home pc that we wish to access over the internet from an arbitory location. for ease we'll assume the ip of the home pc is static, and behind a nat router or similar. Internet hands us 123.123.123.123 on the home pc and we have an internal ip of 192.168.1.100 we want access to 192.168.1.100 when we connect in from our pc wherever it is. there are 2 ways to achieve this with openvpn, with a bridged vpn or a routed vpn, we'll briefly explain both: routed vpn: This style of vpn needs an ip address for each end of the vpn link, and you route trafic over the vpn to the remote endpoint. we'll make the addresses for the vpn different to distinguish them. we've decided that our vpn subnet will be 10.20.30.0/30 with addresses taken from this range. you are using static keys so we have one client and one server. your server will be 10.20.30.2 and your client will be 10.20.30.3 on the vpn. These are addresses used by openvpn itself to route trafic. this means on the client we will end up with a point to point link from 10.20.30.3 to 10.20.30.2. ON the server it is from 10.20.30.2 to 10.20.30.3 If we set stuff up correctly we can talk to your home pc on either the actual address or the virtual one. we tell the client it is to connect to 123.123.123.123 so we use remote 123.123.123.123 1194 on 123.123.123.123 we forward port 1194 to internal host 192.168.1.100. the 2 openvpn processes connect and you end up with a tun interface under Windows with 10.20.30.3 pointopoint 10.20.30.2 netmask 255.255.255.252 If you have ipv4 forwarding enabled on your home pc, you can now talk to 10.20.30.2 from your remote client, and also 192.168.1.100 but you can't get to the internet from here and you can't get to anything else on your subnet. To get to the rest of your home subnet your router machine needs to have a route back to the vpn box i.e. 10.20.30.0/30 gw vpnbox If you don't have ip forwarding enabled you'll reach 10.20.30.2 and nothing else however usually most services listen on 0.0.0.0 so this will allow you to ssh in or use a proxy on that box etc. What we have is a routed vpn. Trafic destined for 10.20.30.2 from your remote takes this path: remote box, 10.20.30.3 -> encapsulate in ethernet frame and compress, tunnel over vpn. vpn sends packets to remote 123.123.123.123 on port 1194 packets are decapsulated and received on tun0 of server to address 10.20.30.2 If you want to access the internet from your remote pc using your home internet connection you need to arrange for the vpn server to nat for 10.20.30.0/30 using iptables. Firewall must accept all trafic from tun0, and allow ip forwarding between tun0 and your internet facing interface. If you set the default gateway to your home vpn box without taking special steps you'll knock out the ability of the client to send packets to the internet thereby stopping the vpn dead in its tracks. Essentially resetting the default route will knock the tree branch that you are standing on out from under you. What needs to happen is a route to 123.123.123.123/32 needs to go through your current default gateway _before_ you set your 0.0.0.0 route to point to 10.20.30.2. bridged solution: An ethernet bridge is a device that connects 2 network segments together. The Linux bridging code and the Windows code supports spanning tree and will take care of trafic loops. To do a bridged vpn you need to use tap0 not tun0. tap0 deals with ethernet frames and can pass any protocol not just tcp/ip. configure a bridge on the linux box with something like openvpn mktun tap0 brctl addbr br0 brctl addif br0 eth0 tap0 ifconfig br0 192.168.1.100. the ip address needs to be assigned to the bridge, not any of the indevidual interfaces on the bridge. Debian's ifup and ifdown scripts have support for bridges, you want a bridge between your ethernet and tap0 interface, googling will give you solutions to this. once you connect to the bridge under Windows, you end up with a virtual interface connected to your remote subnet. You get handed an address either by openvpn's bridging code, or the remote dhcp server on your remote subnet. Problem is if you get handed a default gateway you'll knock out your connection to the internet. On our earlier example you will end up with an address on the 192.168.100.0/24 subnet on your client's tap0. You won't have a default gateway though so either use a proxy or investigate routed vpn. Talk to me off-list about possibly getting the openpn book if you really want to persist with this.

It looks like you're using Windows as a client. Try setting the dns server for the Openvpn tap device to the address of your server on the VPN (like 10.8.0.1 unless you change something somewhere)...I've found you need to do that in order to redirect traffic through the vpn.
