I am trying to configure a VPN under Ubuntu and openVPN. I have followed this guide: https://help.ubuntu.com/10.04/serverguide/C/openvpn.html but I can't conect from any client, I always get a timeout error.
In my opinion, the problem is located in the bridge configuration. According to Ubuntu wiki, I should configure a bridge interface this way:
auto lo iface lo inet loopback auto br0 iface br0 inet static address 192.168.0.10 network 192.168.0.0 netmask 255.255.255.0 broadcast 192.168.0.255 gateway 192.168.0.1 bridge_ports eth0 bridge_fd 9 bridge_hello 2 bridge_maxage 12 bridge_stp off
But I am not sure about the values I have to assign to adress, network, netmask, broadcast and gateway.
The output of ifconfig is the following one (the IP is not real):
eth0 Link encap:Ethernet HWaddr 00:19:99:14:01:d1 inet addr:220.127.116.11 Bcast:18.104.22.168 Mask:255.255.255.255 inet6 addr: fe80::219:99ff:fe14:1d1/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:1147011 errors:1 dropped:0 overruns:0 frame:1 TX packets:2052888 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:78775595 (78.7 MB) TX bytes:2585422360 (2.5 GB) Interrupt:20 Base address:0xa000 lo Link encap:Local Loopback inet addr:127.0.0.1 Mask:255.0.0.0 inet6 addr: ::1/128 Scope:Host UP LOOPBACK RUNNING MTU:16436 Metric:1 RX packets:5040278 errors:0 dropped:0 overruns:0 frame:0 TX packets:5040278 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:1991710982 (1.9 GB) TX bytes:1991710982 (1.9 GB)
My server is a dedicated one; mi local IP, the public IP and the broadcast are the same. I do not know if this is common in a dedicated server.
My current /etc/network/interfaces is the following one:
auto lo iface lo inet loopback auto eth0 iface eth0 inet dhcp auto br0 iface br0 inet static address 22.214.171.124 network 192.168.0.0 netmask 255.255.255.0 broadcast 192.168.0.255 gateway 126.96.36.199 bridge_ports eth0 bridge_fd 9 bridge_hello 2 bridge_maxage 12 bridge_stp off
Maybe the problem is anywhere else but I am not sure about this file being correct.
I would appreciate any kind of help, thank you in advance.
