############################################################################## # # Shorewall 2.0 -- Network Address Translation Table # # /etc/shorewall/nat # # This file is used to define one-to-one Network Address Translation # (NAT). # # WARNING: If all you want to do is simple port forwarding, do NOT use this # file. See http://www.shorewall.net/FAQ.htm#faq1. Also, in most # cases, Proxy ARP is a better solution that one-to-one NAT. # # Columns must be separated by white space and are: # # EXTERNAL External IP Address - this should NOT be the primary # IP address of the interface named in the next # column and must not be a DNS Name. # INTERFACE Interface that we want to EXTERNAL address to appear # on. If ADD_IP_ALIASES=Yes in shorewall.conf, you may # follow the interface name with ":" and a digit to # indicate that you want Shorewall to add the alias # with this name (e.g., "eth0:0"). That allows you to # see the alias with ifconfig. THAT IS THE ONLY THING # THAT THIS NAME IS GOOD FOR -- YOU CANNOT USE IT # ANYWHERE ELSE IN YOUR SHORWALL CONFIGURATION. # INTERNAL Internal Address (must not be a DNS Name). # ALL INTERFACES If Yes or yes, NAT will be effective from all hosts. # If No or no (or left empty) then NAT will be effective # only through the interface named in the INTERFACE # column # LOCAL If Yes or yes and the ALL INTERFACES column contains # Yes or yes, NAT will be effective from the firewall # system ############################################################################## #EXTERNAL INTERFACE INTERNAL ALL LOCAL # INTERFACES #LAST LINE -- ADD YOUR ENTRIES ABOVE THIS LINE -- DO NOT REMOVE
