OpenVPN Support Forum

I'm having issues on new windows client that i recently added to my vpn, the situation is this.

I got one server running arch linux and openvpn that has been working fine with one linux client (both linux are acting as firewall and router),recently my customer added a new branch that has windows xp servers behind a firewall.

In order to make it work i've setup the networks like this.

Home Branch
Server - Router and Firewall
Tun0 10.0.0.1 10.0.0.2
Int. Card 192.168.1.254
Ext. Card 200.x.x.x.x

Branch 1
Linux Client - Router and Firewall
Tun0 10.0.0.4 10.0.0.5
Int. Card 192.168.2.254
Ext.Card 200.x.x.x

Branch 2
Router - (doesn't forward any port to client. might be the issue?)
Int. 192.168.3.1 (acts as dhcp and gives 192.168.3.x adresses).

Windows Client
Eth. 192.168.3.107
Tap. 10.0.0.8 10.0.0.9

On branch 1 i can route 192.168.1.x by manually adding routes to the linux and i can go both ways from 192.168.1.x to 192.168.2.x and from 192.168.2.x to 192.168.1.x with no problems at all, just by adding that route.

On branch 2 i can connect to the vpn via the 10.0.0.8 or the 10.0.0.9 but even adding the route manually i cant ping from the windows client to the 192.168.1 network, or from a windos machine in the home office network to the 192.168.3 net, or access the 10.0.0.8 or 10.0.0.9 machine which are the clients ips. Even though from the linux server i can ping both nets and even telnet to 192.168.3.x 3389 port.

Anyone can see what i'm missing? a forwar rule on the server? network rules ? firewall chains? your help will be highly appreciatted.

Could you post the config files of server, branch 1 and branch 2 clients? Don't worry, no one can hack in unless you also post the certificate.

And also whatever config files of the <configdir>/ccd/ directory on the server?

And whatever differences between the server's mention on the two networks? Like, do you push-route something to branch1 that you don't to branch2?

And... why do you add another network there, the 192.x? Why not just use the 10.0.0.x, 10.0.1.x, 10.0.2.x and so on? Then it would be a lot easier for you when you have individuhals with openVPN clients on their computers (working from hotel rooms etc)?
