Hi!
I have a problem and i was hoping someone could find a solution here.
backgroud:
What I wanted when i decided to install openvpn in my ubuntu server, was that i could connect to my private network outside (eg. my work) and access for instance other ports on that server (security) and other computers on it.
lan ips:
router: 192.168.1.1
server: 192.168.1.45
problem:
on my server side i get an error

# Suppose that you want to enable different
# firewall access policies for different groups
# of clients. There are two methods:
# (1) Run multiple OpenVPN daemons, one for each
# group, and firewall the TUN/TAP interface for each group/daemon
# appropriately. (2) (Advanced) Create a script to dynamically
# modify the firewall in response to access
# from different clients. See man
# page for more info on learn-address script.

# If enabled, this directive will configure all clients to redirect their
# default network gateway through the VPN, causing all IP traffic such as
# web browsing and and DNS lookups to go through the VPN (The OpenVPN
# server machine may need to NAT or bridge the TUN/TAP interface to the
# internet in order for this to work properly).

# Uncomment this directive to allow different clients to be able to "see"

# clients to only see the server, you will also need to appropriately
# firewall the server's TUN/TAP interface.

# Uncomment this directive if multiple clients might connect with the
# same certificate/key files or common names. This is recommended only
# for testing purposes. For production use, each client should have its

# CERTIFICATE/KEY PAIRS FOR EACH CLIENT,

# By default, log messages will go to the syslog (or

# Use log or log-append to override this default.

# while "log-append" will append to it. Use one
# or the other (but not both).

;mute 20I would really appreciate if someone could take a look at these especially the server.conf file because i'm not sure if would even work if/when i get connection.
Thanks!
