Everything looks configured well. From any client I can ping with, but can't reach other clients.

Here is my server.ovpn

port 1200

proto udp

dev tun

ca "C:\\Program Files (x86)\\OpenVPN\\config\\ca.crt"
cert "C:\\Program Files (x86)\\OpenVPN\\config\\server.crt"
key "C:\\Program Files (x86)\\OpenVPN\\config\\server.key"

dh "C:\\Program Files (x86)\\OpenVPN\\config\\dh2048.pem"


ifconfig-pool-persist ipp.txt

keepalive 10 120

tls-auth "C:\\Program Files (x86)\\OpenVPN\\config\\ta.key" 0 

cipher AES-256-CBC   # AES



status openvpn-status.log

verb 3

And client.ovpn


dev tun

proto udp

remote 1200

resolv-retry infinite



ca "C:\\Program Files\\OpenVPN\\config\\ca.crt"
cert "C:\\Program Files\\OpenVPN\\config\\Karol-Komputer.crt"
key "C:\\Program Files\\OpenVPN\\config\\Karol-Komputer.key"

tls-auth "C:\\Program Files\\OpenVPN\\config\\ta.key" 1

cipher AES-256-CBC


verb 3

What could be wrong?

By default, clients can only communicate with the server, not other clients. According to the manual's section on configuration files, you can lift this restriction by adding the directive client-to-client to the server configuration.

Well, it doesn't work. I suppose that it could be because there is no default gateway set so packets doesn't know where to go. –  Disa Dec 27 '12 at 12:22
You probably wouldn't want to change the default gateway, but your configuration isn't pushing routes; clients may not have them. Add to the route table and make sure the server OS is routing packets (HKLM\SYSTEM\CurrentControlSet\Services\TcpIp\Parameters\IpEnableRouter). Check whether firewalls are blocking ICMP echo requests. –  Marcks Thomas Dec 27 '12 at 15:12
Yea, probably that was the problem. Thanks! –  Disa Dec 27 '12 at 16:01
