Re: [Openvpn-users] OpenVPN Routing Issue

1.) You forgot your server and client config files
2.) Try deleting the iroute parameter

Subject: [Openvpn-users] OpenVPN Routing Issue

Hi Everyone,


I’m a new-ish user to OpenVPN, and I’m having a small issue with it..

I’m using it to run a VPN to a new remote office that I am setting up.


I have an openVPN server running here in our main office. It runs on Windows 2003, site here on our LAN ( and has the appropriate port forwarded to it from our Cisco PIX firewall.


The satellite office openVPN is also running on Windows 2003 ( I’ve not installed routing and remote access as I’ve read this can cause problems, but I have manually enabled IP routing in the registry. The same has been done on the server.


I’ve created a basic tunnel config for the server and the client. The VPN connects ok, and I can ping server to client and client to server using the VPN IP addresses.

I’ve pushed the server LAN route through to the client (push "route"), and have included the client IP also (route

I have a file with the same name as the client cerfiticate in the CCD folder, with the line “iroute” in it.

Finally, I have added a route to the network on the router that is the default gateway in the main office.

The default gateway in the satellite office is the VPN server.


Now comes my problem.

From the VPN server I can ping the VPN client using it’s real IP address. I can also ping any machines on the VPN client local LAN – great!

However, I can’t seem to be able to ping anything on the Server side LAN from the VPN client machine. I can ping the VPN server by it’s real IP (, but can’t ping anything else on that LAN. A tracert shows the traffic routing to (which I believe is the IP of the Server VPN adapter) but it times out from then on.


At first I thought it was a problem with the routing on the server side lan, but then I realised that any other PC on the client side LAN can ping anything on the server side LAN. It’s only the VPN client itself that can’t ping anything on the server LAN.


I’ve read through the documentation several times, but can’t seem to find out where I’ve gone wrong.


Any assistance that anyone can give me will be greatly appreciated!
