Yaniv:
Since the tun device is created you can reference them as another network
interface and configure the iptables rules as normal.
Hope this help,

Hi experts

eth0.10.90.20.3/24
tun0=172.16.10.x/24
eth0 configure as Wan interface
eth1/tun0 are lan interface .
tun0 network 172.16.10.200 => web server
in side my tun0 there is a web server i need to manage for the outside
world (eth0, it can also be restricted to specific ip address )
i am trying to find a way using port forwarding to enable this .
can some one please help me modify my correct iptables rules
IPTABLES="/sbin/iptables"
EXTIF="eth0"
INTIF="eth1"
#Flush all rules
$IPTABLES -F
$IPTABLES -F -t nat
$IPTABLES -F -t mangle
#Set default behaviour
$IPTABLES -P INPUT DROP
$IPTABLES -P FORWARD ACCEPT
$IPTABLES -P OUTPUT ACCEPT
#Allow related and established on all interfaces (input)
$IPTABLES -A INPUT -m state --state RELATED,ESTABLISHED -j ACCEPT
#Allow releated, established and ssh on $EXTIF. Reject everything else.
$IPTABLES -A INPUT -i $EXTIF -p tcp -m tcp --dport 22 --syn -j ACCEPT
#$IPTABLES -A INPUT -i $EXTIF -p tcp -m tcp --dport 80 --syn -j ACCEPT
$IPTABLES -A INPUT -i $EXTIF -j REJECT
#Allow related and established from $INTIF. Drop everything else.
$IPTABLES -A INPUT -i $INTIF -j DROP
#Allow http and https on other interfaces (input).
#This is only needed if authentication server is on same server as chilli
$IPTABLES -A INPUT -p tcp -m tcp --dport 80 --syn -j ACCEPT
$IPTABLES -A INPUT -p tcp -m tcp --dport 443 --syn -j ACCEPT

$IPTABLES -A INPUT -p icmp --icmp-type echo-request -j ACCEPT
#Allow everything on loopback interface.
$IPTABLES -A INPUT -i lo -j ACCEPT
# Drop everything to and from $INTIF (forward)
# This means that access points can only be managed from ChilliSpot
$IPTABLES -A FORWARD -i $INTIF -j DROP
$IPTABLES -A FORWARD -o $INTIF -j DROP
#Enable NAT on output device
$IPTABLES -t nat -A POSTROUTING -o $EXTIF -j MASQUERADE
