# You will need to change these variables...

# The host name or IP address of the SSH server that we are
# sending the connection request to:
SERVER_HOSTNAME=ff.somehost.tld
# The username on the VPN server that will run the tunnel.
# For security reasons, this should NOT be root. (Any user
# that can use PPP can intitiate the connection on the client)
SERVER_USERNAME=cyber
# The VPN network interface on the server should use this address:
SERVER_IFIPADDR=172.30.29.5
# ...and on the client, this address:
CLIENT_IFIPADDR=172.30.29.6
# This tells ssh to use unprivileged high ports, even though it's
# running as root. This way, you don't have to punch custom holes
# through your firewall.
