After a while (some time of not using), the OpenVPN server broke down.
The secured connection istablishes, but IP does not go.
I guess, the problem in the IP routing. I don't know what I did, but after server rebooted, the connection start working.
The routing table on the server looks as below:
C:>route print 10.8*
IPv4 Route Table
0x1 ........................... MS TCP Loopback interface
0x2 ...00 ff 3d 7b 61 e5 ...... TAP-Win32 Adapter V8
0x10004 ...00 13 72 69 2d 0c ...... Broadcom BCM5708C NetXtreme II GigE (NDIS VBD Client)
Network Destination Netmask Gateway Interface Metric
10.8.0.0 255.255.255.252 10.8.0.1 10.8.0.1 30
10.8.0.0 255.255.255.0 10.8.0.2 10.8.0.1 1
10.8.0.1 255.255.255.255 127.0.0.1 127.0.0.1 30
Default Gateway: 10.0.0.1
There are still questions for me. Why routing to 10.8.0.0 via two gateways - 10.8.0.1 and 10.8.0.2 ?
10.8.0.1 - is the address of the TAP IP interface, but what is 10.8.0.2 then?
The address of the "modem pool"?
Same way, on the client the interface address 10.8.0.6, but 10.8.0.5 - P-t-P - what's that?
Good instructions about setting OpenVPN up are located here:
And don't forget, when you want to connect a machine behind the server it has to have route to the 10.8.0.0 network as well.
