OpenVPN with DHCP

[Christoph Brill <egore gmx de>]

Hi list,

I'm trying to connect to a openvpn server. This server is set up to use
the companies DHCP server (dnsmasq) to provide IPs to the VPN clients.
>From what I understand (reading the error message of nm-applet)
NetworkManager currently relies on using OpenVPNs internal "DHCP
server". Is that true?

I use OpenVPN to establish a connection and provide me a tap0 interface.
After that I use a DHCP-client to get an adress for the tap0. Is
NetworkManager able to use OpenVPN just as a "transport layer"?

-----------------------------
Example client configuration:
-----------------------------
remote XXX
proto tcp-client
port 1194
client
dev tap0
verb 3
persist-tun
persist-key

status /tmp/openvpn-status.log
log-append /var/log/openvpn.log

ca /etc/openvpn/XXX/ca.crt
cert /etc/openvpn/XXX/YYY.crt
key /etc/openvpn/XXX/YYY.key

pull
resolv-retry infinite
ns-cert-type server
tls-remote XXX

-----------------------------
Example server configuration:
-----------------------------
proto tcp-server
port 1194
mode server
dev tap0
verb 3
persist-tun
persist-key
user openvpn
group openvpn
tls-server

status /tmp/openvpn-status.log
log-append /var/log/openvpn.log

ca /etc/openvpn/XXX/ca.crt
cert /etc/openvpn/XXX/YYY.crt
key /etc/openvpn/XXX/YYY.key
dh /etc/openvpn/XXX/YYY.pem

client-to-client
push "dhcp-option DNS 192.X.Y.Z"
push "dhcp-option DOMAIN XXX.YYY.ZZZ"
keepalive 10 120
max-clients 20


Thanks and keep up the good work,
