Hi all

I am using openvpn-2.2.0-rc6 on linux. I had tls to tls vpn working now I am trying to get the sever - client working now.

The server.conf
---------------------------------------------
server 192.168.254.0 255.255.255.0
push 192.168.0.0 255.255.224.0
route 192.168.34.0    255.255.255.0
...
The problem is the tun0 on the server is point to point to
192.168.254.1 PtoP 192.168.254.2
the routing is also

# route
192.168.34.0 192.168.254.2 255.255.255.0

BUT on the client

tun0 is
192.168.254.6 192.168.254.5

with route
192.168.254.1 192.168.254.5 255.255.255.255 UGH 0 0 0 tun0
192.168.34.0 * 255.255.255.0 U 0 0 0 eth0
192.168.0.0 192.168.254.5 255.255.224.0 UG 0 0 0 tun0



Why doesn't the routing match? the 2 PtoP should be inverse.


Why? Is it a problem or would you just have prefered to have it inversed?





If you need the whole configuration I can send it, but I hope I the limited config will be enough to know the problem.


Your client is assigned 192.168.254.6, and the routing table says that it can reach 192.168.254.1/255.255.255.255 and 192.168.0.0/255.255.224.0 through 192.168.254.5. Looks fine to me.

What problems are you having?

from the server 192.168.254.1 does not pin 192.168.34 net from the server net 192.168.0 does not ping the 192.168.34 net from client net 192.168.34 does not ping 192.168.0 net

the routing from the server sends 192.168.34.packets to 192.168.254.2 but the IP on the client side is 192.168.254.6

When I del the 192.168.34 route and try to add route to 192.168.34 using 192.168.254.6 there is no interface.

Looking at the server logs I see the route to 34 net is added before 34 net connects.

in short I can't tunnel through the VPN.

---------------------------------------------
I concept of what it should be

server tun0 192.168.254.1 PtoP 192.168.254.6
server route 192.168.34.0/24 gw 192.168.254.6

client tun0 192.168.254.6 PtoP 192.168.254.1
client route 192.168.0/20 gw 192.168.254.1

when the next is added (I guess)

server tun1 192.168.254.1 PtoP 192.168.254.10
server route  192.168.35.0/24 gw 192.168.254.10

Don't try to ping .5, it won't work! Try pinging 192.168.254.1 to see if your tunnel works.
