I have set up a separate routing table (tovpn)

#echo 200 tovpn >> /etc/iproute2/rt_tables  

Now I assign routes to it.

Where is the tun2 P-t-P and is the inet

#ip route add dev tun2 table tovpn  
#ip route add default via dev tun2 table tovpn  

Some network has traffic forwarded to the table

#ip rule add from table tovpn  
#iptables -t nat -A POSTROUTING -s -o tun2 -j MASQUERADE  

Great, everything works.

How do I specify traffic additional traffic to pass through the tunnel by specifying the host ip?

The following does not work, if I would like to route, for example, traffic to over the tunnel.

#ip rule add to table tovpn  


#ip rule add to lookup tovpn  

Any assistance would be greatly appreciated, thank you.

My routing table was incorrectly setup. Correct setup as follows:

# ip route add $PTPADDR src $INETADDR proto kernel dev tun1 table tovpn  
# ip route add default dev tun1 table tovpn  

Now mark packets with

# iptables -t mangle -A PREROUTING -i $LANINTERFACE -d -j MARK --set-mark 300
