RaidenMAILD Help - Firewall -
RaidenMAILD firewall is a lite firewall designed for blocking hostile IP address. It's technology is based on Windows IP Filter Driver. The configuration is in [Server settings]->[Basic]->[Options]->[IP Restriction]->[IP/Domain Deny List]->[Configure Firewall]. The configuration screen is below: Action DROP means deny a connection. PASS means allow a connection. From IP Address IP Address: It means remote host IP address. Network mask: Empty means single IP address. /24 means class C of IP address. /16 means class B of IP address. /8 means class A of IP address. Port: (no necessary to specifiy this) Destination IP Address IP Address: It means local host IP address. Most of case is 0.0.0.0/0 (ANY), or you can specify a single IP address on local machine. Network mask: (no necessary to specifiy this) Port: The port on local to be filtered. You can specify port range by dash sign ( "-" ), ex: 1-1024 means port from 1 to 1024. The GUI is only designed for raidenmaild to block IP address. However, this firewall can do more than this. You can refer the original rules document below. ======================================================= # ---------------------------------------------------------------------------- # IP Firewall Lite Rules Examples # Rules format: Rules are applied from TOP to BOTTOM! All reserved words must be in uppercase! # WARNING : THIS IS A SAMPLE AND MUST NOT BE APPLIED TO FIREWALL BECAUSE # IT MAY NEGATIVELY AFFECT NETWORK PEFORMANCE AND SECURITY! # ---------------------------------------------------------------------------- # # # IP rules: # # PASS|DROP IP FROM <addr> TO <addr> [IPPROTO <ipproto>] [NOLOG] # # # Where <addr> is IP-address and possibly netmask (192.168.0.0/24) or "ANY" # <addr> ::== ANY # is equal to 0.0.0.0/0 # # And <ipproto> is IP-protocol number. See etc\protocol file. # # # Example: # # PASS IP FROM ANY TO 192.168.0.0/24 IPPROTO 1 NOLOG # DROP IP FROM ANY TO 127.0.0.1 # # ---------------------------------------------------------------------------- # # TCP rules: # # PASS|DROP TCP FROM <addr> TO <addr> [FLAGS <flags>] [NOLOG] # # Where <addr> is IP-address and possibly netmask or port range # <addr> ::== <ip_address>[/<mask>][:<port>[-<port2>]]or # for example 192.168.0.1:1-1023 , 192.168.0.0/24 or # # And where <flags> is sequence of one or some TCP-flags: A P S R F U E C # and '+' or '-' character after (flag is set or flag is not set) # Be carefull while using flags...If stateful inspection is activated, # you must be very careful to (albeit not suggested) use them. # # Example (deny incoming connections to privileged ports from some subnet): # # DROP TCP FROM 192.168.5.0/24 TO 0.0.0.0/0:1-1024 FLAGS S+A- # # ---------------------------------------------------------------------------- # # UDP rules: # # PASS|DROP UDP FROM <addr> TO <addr> [NOLOG] # # Where <addr> is similiar to TCP rules case. # # Example: # # PASS UDP FROM ANY TO 0.0.0.0/0:53 # PASS UDP FROM 0.0.0.0/0:53 TO ANY # ---------------------------------------------------------------------------- # # ICMP rules: # # PASS|DROP ICMP FROM <addr> TO <addr> [TYPE <type>[.<code>] [NOLOG] # # Where <addr> is similiar for TCP rules case. # # And <type> and <code> is ICMP types and codes. # For example echo request is 8.0 and echo reply is 0.0. # # Example: # # PASS ICMP FROM ANY TO 192.168.0.1/32 TYPE 8.0 # # ---------------------------------------------------------------------------- ======================================================= < Back to Index RaidenMAILD Official Site: http://www.raidenmaild.com Copyrights 2008, Team John Long.
