OPENVPN - 1 - ROUTED VPNS - CLIENT 2 CLIENT ############################################# ############################################# I do not claim ownership to the manpage of openvpn and also the vars file ( i did some edits ) and also the client/server settings before the errors section, I just used them as experts to help you in your reading. Note here I cover how to make a very simple openvpn with static keys (but its not very secure) and then one with more security using ssl/tls pki certs. ################ ################ ################ ################ OPENVPN - Routed ################ ################ ################ ################ TABLE OF CONTENTS: 1.

We are doing routed vpn here for simplicity meaning the client will only be able to have a direct connection to the server and nothing beyond that unless there were routes in place on the servers network telling pcs on that network that to reach the client they have to go through the server. IF you want a vpn where the client has access to the whole network instead of setup like that with routes, its simpler to implement the other type of vpn, a bridged vpn, but thats another article/topic. ######################### ######################### Routed Static Key OpenVPN ######################### ######################### SIMPLEST VPN REQUIREING A PRESHARED KEY (A FILE, NOT A PASSPHRASE) There is actually a simpler VPN then this which requires no key, but noone should do a tunnel without some sort of encryption. Then after that simplicity comes this setup where you just need 1 file on both client and server. then after that comes strongest PKI using SSL/TLS keys. So thats the 3 levels 1) no key 2) preshared key 3) PKI with SSL/TLS Below I will post some good links on this. After that notice that on the server we give ourselfs an ip of 10.99.99.1 and a gateway of 10.99.99.2 (Which will be the client) and vice versa on the client. Just make sure to be root. THE ONLY PREREQUISTE FROM A NETWORKING POINT OF VIEW: * Allow outbound all out on server network * Allow outbound all out on client network (IMPORTANT SIDE NOTE - applies to this point and the point below about portforwarding:specifically port 50006 UDP in this case, by default - and on most sites - you see port 1194, I use UDP as its best to use UDP for VPNS, there are plenty of articles of why TCP is a terrible choice, one being when you have a TCP stream going thru a TCP vpn you get TCP over TCP phenomenon where nothing aligns, each TCP requires its own AWK blah hack... you know what im talking about its a mess, thus UDP is best) * Portforward from your router 1 UDP or TCP port (Like I said we are using UDP as its best and im not using the default 1194 so im using 50006 from the router[www.server.com] to the openvpn server[which is inside the www.server.com routers network of course]... Note for those interested in how this setup would look like if I port-translated with my portforward, for example I said port 50006 from www.server.com router goes to port 2000 on the openvpn server, well the server config would have to say "port 2000" & "proto udp" and the client would have to say "remote www.server.com" & "port 50006" & "proto udp" ) ============= SERVER CONFIG ============= GEN KEY: cd /etc/openvpn openvpn --genkey --secret static.key vi openvpn.conf OPENVPN.CONF: proto udp port 50006 dev tun ifconfig 10.99.99.1 10.99.99.2 secret static.key START THE VPN ON THE SERVER (AND HOPEFULLY YOU GET OKS INSTEAD OF FAILS) service openvpn start OR /etc/init.d/openvpn start TRANSFER KEY TO CLIENT FROM SERVER cd /etc/openvpn cat static.key | ssh -p 50005 www.client.com "cat - > /etc/openvpn/static.key" ============= CLIENT CONFIG ============= We need to get the key here, looks like we did that above :-) Next comes the config cd /etc/openvpn vi openvpn.conf OPENVPN.CONF: remote www.server.com proto udp port 50006 dev tun ifconfig 10.99.99.2 10.99.99.1 secret static.key START THE VPN ON THE CLIENT (AND HOPEFULLY YOU GET OKS INSTEAD OF FAILS) service openvpn start OR /etc/init.d/openvpn start ===GOOD READING:=== http://openmaniak.com/openvpn_tutorial.php Read all the sublinks with this as well as they give good information.
