why it works well with windows and not whit linux (u.dapper)  :'(

Might want to ask that on a Ubuntu forum.  If it works with windows, well…

Not sure how dapper fits into this scheme

to make a situation like this

internet -> pfsenseGw (pubblic IP) <-  … openvpn tunnel ...-> natted ubuntu dapper

p-to-p openvpn tunnel with simple shared secret key
forward specific traffic (http 80, passive ftp 21) from internet to the natted ubuntu dapper

it's possibile to make it work witch pfsense 1.0.1 ?
this parameters in the web interface are correct?

Proto UDP
l.port 1194 
A.pool 10.0.8.1/30
crypto BF-CBC 128bit
Auth.metod shared key

#
	# 2048 bit OpenVPN static key
	#
	-----BEGIN OpenVPN Static key V1-----
cut
        -----END OpenVPN Static key V1-----
#

Custom options

The udp 1194 open on the wan interface
and the client config like something this

remote 31.1.2.133 1194
port 1194 
dev tun
ifconfig 10.0.8.2 10.0.8.1
#dev-node ovpn
proto udp
ping 10
secret /etc/openvpn/udugw/static.key
persist-tun
persist-key
#tls-client 
#ca ca.crt
#cert client1.crt
#key client1.key
#ns-cert-type server
#comp-lzo
#pull
log /var/log/openvpn.log

not work :(

the connection was active

-```
$ /etc/init.d/openvpn restart

and the tun interface up

-pftop (really great! :)) server:

but the client can't ping the server by the tunnel
