Host A

eth0: 192.168.2.171

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

local net

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

#---------------------------------

#!/bin/sh

 

#value after “-net” is the subnet behind the remote peer route add -net 192.168.4.0 netmask 255.255.255.0 gw $5

#---------------------------------

end ------------------------------

Create a configuration file named B-tun.confand an executable script file named B-tun.shon OpenVPN B:
