I am trying to configure OpenVPN on m0n0,version 1.2b10 and seeing the
following error in the logs:

Oct 14 03:35:58 smithgw openvpn[477]: OpenVPN 2.0.2 i386-unknown-freebsd4.11
[SSL] built on Sep 11 2005
Oct 14 03:35:58 smithgw openvpn[477]: WARNING: --keepalive option is missing
from server config
Oct 14 03:35:58 smithgw openvpn[477]: Cannot load DH parameters from

line
Oct 14 03:35:58 smithgw openvpn[477]: Exiting


I am using RSA Authentication, I generated my keys using the
easy-rsa(including the DH), what does this error mean?  

Please let me know what other information you may need and thanks.
