openvpn
I am trying to set up OpenVPN to allow me to connect a number of laptops to my network in a way that allows the laptops to connect to specific computers via HTTP (to e.g. a server management page) and windows shares (to access files)
In the test environment my laptops live in a network with a 192.168.1.X address range. The host-network has a 10.66.77.X address range The server hosting the OpenVPN server has address 10.77.10.20. I need to access some application server web pages on this machine, accessible on various ports The server with the windows shares as well as some other web based pages I need to access is on address 10.66.77.20
The config files for server and laptop are attached below. The laptop establishes the VPN connection without problems, but I cannot access any of the machines, even a simple ping fails. Maybe a routing problem? The routing table for the laptop is shown below as well - every idea is appreciated!
Thanks! Maik
