If you still have subnet conflict than you have to solve this first.
you have the same subnet (10.0.0.0/24) on two points.
change this!!! restart openvpn server and try again.

I solved my conflict problem by check redirect gateway from openvpn server settings

redirect gateway : Force all client generated traffic through the tunnel.

but still can't ping or map my network drive

this my new openvpn log file

Did you create Firewall rules according to the tunnel network (subnet) on the new OpenVPN firewall tab ?

hossam.khalili

on the new openVPN tab I found this rule

protocol source port Destination Port Gateway Queue

* * * * * * none

is this enough ? or I need to add something else.

thanks.

Nachtfalke

This is enough. It allows all traffic from all OpenVPN connections to everywhere.

Can you do a tracert from the OpenVPN Client and check till which point/hop the traffic comes ?
Are you sure that the firewall of the destination's host is correctly configured? Perhaps try with complete turned off firewall first.

can you post a screenshot or something else of your network topology ?

hossam.khalili

hello,

thanks for reply, i do nothing on the destination host

should i do something on it ? ;D

hossam.khalili

this's my network environment

office 1
pfsense 2.0-RELEASE (i386)
LAN : 10.0.0.0/24
WAN : 212.38.142.254

i have more than one LAN in this office

office 2
pfsense 2.0-RELEASE (i386)
LAN : 10.0.1.0/24
WAN : 212.38.142.151

Nachtfalke

on office1 you have to:

push "route 10.0.0.0 255.255.255.0";

So the client (office2) gets an route through openvpn to your LAN on office1.
If you configured this correct and configured the correct firewall rules on both sites than this should be possible:

pfsense (office2) from GUI can ping pfsense (office1) and clients on office1 LAN and vice versa.

So now I am not sure at all but you need additional configuration on the client (office2) so that the LAN(s) behind this router are reachable.
On office1 you could add a client specific override for the client (office2). Add this in advanced options:

iroute 10.0.1.0 255.255.255.0;

Restart OpenVPN Server (office1) and Client (office2).

But take a look here:

Ok, after a week of this…I may be alone here, but I feel like if we had all the particulars up front, this issue would've been solved several days ago. Lets go back to the beginning... please give us explicit details on what you're trying to do.

At first, it sounded like you were trying to get a road warrior setup going. Now it looks like you may be doing site to site... instead of us speculating and taking pot shots, let us know what you're doing and provide ALL the details so we can help you. Also a network map would be helpful.

hossam.khalili

Okay, it's working now
i change the client machine
thanks for all of you

other thing can i make it automatically connect when windows start i mean on startup windows XP ?
