I have eth0 as the management interface. This following rule helps me in accepting DHCP requests from the other interfaces(VLAN interfaces). The default INPUT policy is DROP. INET_IFACE="eth0" # # Special rule for DHCP requests # $IPTABLES -A INPUT -p UDP -i ! $INET_IFACE --dport 67 --sport 68 -j ACCEPT Now, I have to support upto three other VLAN interfaces as management interfaces in addition to eth0. Please can someone help me in creating a rule for granting access to other interfaces too. Thanks, Gautham ____________________________________________________________ Get advanced SPAM filtering on Webmail or POP Mail ... Get Lycos Mail! http://login.mail.lycos.com/r/referral?aid=27005
