ifconfig 192.168.4.174 192.168.2.173
up /etc/openvpn/tun.sh
Then modify the routing table in /etc/openvpn/tun.sh script file.
#----------------------------------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
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
$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:
