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

#!/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.conf and an executable script file named B-tun.sh on OpenVPN B:

remote 192.168.8.173

dev tun

secret /etc/openvpn/secrouter.key

cipher DES-EDE3-CBC

auth MD5

tun-mtu 1500

tun-mtu-extra 64

ping 40

ifconfig 192.168.4.174 192.168.2.173

up /etc/openvpn/B-tun.sh

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

#!/bin/sh

# value after “-net” is the subnet behind the remote peer

route add -net 192.168.2.0 netmask 255.255.255.0 gw $5

#---------------------------------- end ------------------------------

Note that the parameter “ifconfig” defines the first argument as the local internal interface and the second

argument as the internal interface at the remote peer.

Note that $5 is the argument that the OpenVPN program passes to the script file. Its value is the second

argument of ifconfig in the configuration file.

3. Check the routing table after you run the OpenVPN programs, by typing the command:

# route
