I only wanted the users from eth1 to be able to connect to my web server. users from other interface i.e eth0, eth2.eth3 and eth4 will not be able to connect to my web server. What iptables rule should i use.

run a default drop policy, and then allow what you want:

  iptables -P INPUT DROP
  iptables -A INPUT -m state --state ESTABLISHED,RELATED -j ACCEPT
  iptables -A INPUT -i eth1 -p tcp --syn --dport 10000 -j ACCEPT

-j
