Pavadan Firmware script help

[Rick Mathes]

I have an Asus RT-N56U with latest Pavadan firmware on it. I have it working fine to route all connections through my PIA vpn. My problem is I only want to run one device through the vpn connection. On my Asus RT-Ac68U it was simple but on this router I have to use a script. There are some examples but I am still totally confused. Any help would be greatly appreciated. Below are the examples within the firmware. I just want to route 192.168.1.200 to my vpn. Thanks in advance.

#!/bin/sh

### Custom user script
### Called after internal VPN client connected/disconnected to remote VPN server
### $1 - action (up/down)
### $IFNAME - tunnel interface name (e.g. ppp5 or tun0)
### $IPLOCAL - tunnel local IP address
### $IPREMOTE - tunnel remote IP address
### $DNS1 - peer DNS1
### $DNS2 - peer DNS2

# private LAN subnet behind a remote server (example)
peer_lan="192.168.9.0"
peer_msk="255.255.255.0"

### example: add static route to private LAN subnet behind a remote server

func_ipup()
{
# route add -net $peer_lan netmask $peer_msk gw $IPREMOTE dev $IFNAME
return 0
}

func_ipdown()
{
# route del -net $peer_lan netmask $peer_msk gw $IPREMOTE dev $IFNAME
return 0
}

logger -t vpnc-script "$IFNAME $1"

case "$1" in
up)
func_ipup
;;
down)
func_ipdown
;;
esac

example code:

# By default all traffic bypasses the VPN
iptables -t mangle -A PREROUTING -i br0 -j MARK --set-mark 1
 
# explicitly uses the VPN
iptables -t mangle -A PREROUTING -i br0 -m iprange --dst-range 78.31.8.1-78.31.15.254 -j MARK --set-mark 0
iptables -t mangle -A PREROUTING -i br0 -m iprange --dst-range 193.182.8.1-193.182.15.254 -j MARK --set-mark 0

of course you will need to substitute the IPs/Range and the ethernet's device name
