–route network/IP [netmask] [gateway] [metric]
 
vpn_gateway — The remote VPN endpoint address (derived either from –route-gateway or the second parameter to –ifconfig when –dev tun is specified).
 
net_gateway — The pre-existing IP default gateway, read from the routing table (not supported on all OSes).
 
remote_host — The –remote address if OpenVPN is being run in client mode, and is undefined in server mode.
 
 
route add -net 10.0.0.0 netmask 255.255.255.0 gw $5
 
 
 
Setting parameter 121 in dhcp. Networking and routing between subnets works perfectly.
