kindly find below the rules we had declared on /etc/rc.local

sudo iptables -A FORWARD -i eth0 -s 192.168.1.0/24 -j DROP
sudo iptables -A FORWARD -i eth0 -o eth0 -j DROP

sudo iptables -A FORWARD -d 192.168.0.0/24 -m state --state ESTABLISHED,RELATED -i eth0 -j ACCEPT

sudo iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE

#sudo iptables -t nat -A POSTROUTING -j ACCEPT

sudo iptables -t nat -A PREROUTING -i eth0 -p tcp --dport  5900 -j DNAT --to-dest 192.168.0.203:5900
sudo iptables -t nat -A PREROUTING -i eth0 -p tcp --dport  80 -j DNAT --to-dest 192.168.0.204:80

other than this, no where we had declared any rules

Thanking you,

Sorry for the late reply, work before life now days. .

Your firewall rules should be in a file called iptables. What OS are you running?

Do you have any Policies set for your firewall?
