eth0: 192.168.4.172

local net

OpenVPN A

eth1: 192.168.2.173

eth0: 192.168.8.173

Internet

ixp0: 192.168.8.174

ixp1: 192.168.4.174

Host B

OpenVPN B

2.Create a configuration file named “A-tun.conf” and an executable script file named “A-tun.sh”.

#point to the peer remote 192.168.8.174 dev tun

secret /etc/openvpn/secrouter.key cipher DES-EDE3-CBC

auth MD5 tun-mtu 1500 tun-mtu-extra 64 ping 40

ifconfig 192.168.2.173 192.168.4.174 up /etc/openvpn/A-tun.sh

#---------------------------------	Start-----------------------------
