How to Direct Traffic over VPN?

[bulbous_blues]

Hi I wonder if anyone can help me out.

I'm using AirVPN through my RT AC68 router and I'm trying to have some IP addresses hidden by the VPN and the rest through my local ISP. I created a script called openvpn-event.

#!/bin/sh

Sleep 2

for i in /proc/sys/net/ipv4/conf/*/rp_filter ; do
echo 0 > $i
done

ip route flush table 100
ip route del default table 100
ip rule del fwmark 1 table 100
ip route flush cache
iptables -t mangle -F PREROUTING

ip route show table main | grep -Ev ^default | grep -Ev tun11\
| while read ROUTE ; do
ip route add table 100 $ROUTE
done

ip route add default table 100 via $(nvram get wan_gateway)
ip rule add fwmark 1 table 100
ip route flush cache

iptables -t mangle -A PREROUTING -i br0 -j MARK --set-mark 1

iptables -t mangle -A PREROUTING -i br0 -m iprange --src-range 192.168.1.99 -j MARK --set-mark 0
iptables -t mangle -A PREROUTING -i br0 -m iprange --src-range 192.168.1.88 -j MARK --set-mark 0
iptables -t mangle -A PREROUTING -i br0 -m iprange --src-range 192.168.1.89 -j MARK --set-mark 0

exit 1

I'm really not very good at this stuff and it doesn't seem to be working, at the moment all IP addresses are hidden behind the VPN not just the ones in the script.

Read the documentation regarding policy-based routing. It's configurable through the web interface.

Hi Thanks I hadn't realized it was configurable through the web interface. I have it set up now. A lot easier
