Hello,

I have some problem with my OpenVPN server.

My VPN network is 10.1.0.0/24.
The problem that I am having is that my client gets an /30 IP address, the address that it is getting is 10.1.0.6/30.

I can not ping the server or ping the client from the server.

The server is running gentoo with OpenVPN, and the client Windows XP

[ The tun0 interface on the server ]

tun0 Link encap:UNSPEC HWaddr 00-00-00-00-00-00-00-00-00-00-00-00-00-00-00-00
inet addr:10.1.0.1 P-t-P:10.1.0.2 Mask:255.255.255.255

VPN network = 10.1.0.0/24
Internal LAN = 192.168.1.0/24

This is the first time I am setting up a VPN server and I would be greatful if someone could help me and explain what I am doing wrong.

I fixed the problem, my firewall(iptables) was blocking the tun interface by default

This is what I had to do;

# Allow TUN interface connections to OpenVPN server
iptables -A INPUT -i tun+ -j ACCEPT

# Allow TUN interface connections to be forwarded through other interfaces
iptables -A FORWARD -i tun+ -j ACCEPT
