Yep, I was able to test it after my office closed today. Just popping the static route in when I need it works for me.

What do your firewall rules look like on LAN?

What about the remote openvpn server? Does it have a route back to your LAN subnet? (either via route for shared key, or route/iroute for PKI)

With site-to-site PKI, the "remote network" doesn't really work like that. The Remote Network box is only for Shared Key.

You need to do two things to get site-to-site PKI to route back to the client network:

a) Add a "route 192.168.x.0 255.255.255.0;" line in custom options, one for each remote site.
b) Add a Client-Specific Config entry for each site, using the site's common name of their certificate. In the custom options for this site, add "iroute 192.168.x.0 255.255.255.0;"

Not sure about ubuntu clients, but on Win7 were you running the client as Administrator?

When connected, go to a CMD prompt, and type "route print" and see if you have a route to your home network that has an IP in the OpenVPN address pool as its gateway.

The client doesn't need dh parameters.

As for the other problem, on the road warrior server config, in the custom options, put:

push route 192.168.2.0 255.255.255.0;

And then on the site2 client for site-to-site, in the custom options, put:

route 10.0.0.0 255.255.255.0;

The first part should tell the clients that they can reach site2 via the OpenVPN connection. The second part will tell site2 how to route back to the OpenVPN road warrior subnet.

and the other part of my config

A few simple tests could confirm this behavior, but I'm not sure offhand.

I haven't tried this myself, but you could require having a CSC entry, and use the directive

ccd-exclusive;

In the custom options to enforce the requirement that a client exists on the CSC tab before they can connect.

The OpenVPN man page doesn't really clarify whether or not the ifconfig-push directives for the CSC entries are taken into account during general pool assignment.

Thx i think i got it now. I ve changed Address pool to 10.0.8.0/24 (on servers side) an on client side Interface IP: to 10.0.8.0/24 and now i can ping from hosts on A site to host on B site. Now I am going to play with DNS. Thx once again.

It's resolved. There were two different problems. One was with Tunnelblick. I switched to a different VPN client on the Mac (Viscosity) which worked right away. The problem with the Windows PC was that I was using a different VPN config, who's alias was mistakingly being blocked from DNS via a firewall rule.

This was solved on IRC, I believe. He switched to using a real PKI setup (not shared key/PSK), and adding route/iroute statements as needed, and it started to work.

Never mind, I figured it out. It is base64 encoded, just without line breaks. I just removed all the line breaks from my encoded string.

I'm not sure how it goes on Windows, but on unix, you have to run a different program first that sets variables that makes sure it's reading all of the proper files and such.

Can you try some packet captures to see if the traffic makes it across the tunnel on tun0 and actually leaves (and re-enters) your LAN interface?

Never mind ,
i will skip the VPN settings for now

Thanks ,
it works , i was thinking i could just copy them  :-
anyway thanks again , it solved the problem
