NAME

       zones - Shorewall zone declaration file

SYNOPSIS

       /etc/shorewall/zones

DESCRIPTION

       The /etc/shorewall/zones file declares your network zones. You specify
       the hosts in each zone through entries in /etc/shorewall/interfaces or
       /etc/shorewall/hosts.

       The columns in the file are as follows.

       ZONE - zone[:parent-zone[,parent-zone]...]
           Name of the zone. The names "all", "none", "SOURCE" and "DEST" are
           reserved and may not be used as zone names. The maximum length of a
           zone name is determined by the setting of the LOGFORMAT option in
           shorewall.conf[1](5). With the default LOGFORMAT, zone names can be
           at most 5 characters long.

           The order in which Shorewall matches addresses from packets to
           zones is determined by the order of zone declarations. Where a zone
           is nested in one or more other zones, you may either ensure that
           the nested zone precedes its parents in this file, or you may
           follow the (sub)zone name by ":" and a comma-separated list of the
           parent zones. The parent zones must have been declared in earlier
           records in this file. See shorewall-nesting[2](5) for additional
           information.

           Example:

               #ZONE     TYPE     OPTIONS         IN OPTIONS        OUT OPTIONS
               a         ipv4
               b         ipv4
               c:a,b     ipv4
           Currently, Shorewall uses this information to reorder the zone list
           so that parent zones appear after their subzones in the list. The
           IMPLICIT_CONTINUE option in shorewall.conf[1](5) can also create
           implicit CONTINUE policies to/from the subzone.

           In the future, Shorewall may make additional use of nesting
           information.

       TYPE

           ipv4
               This is the standard Shorewall zone type and is the default if
               you leave this column empty or if you enter "-" in the column.
               Communication with some zone hosts may be encrypted. Encrypted
               hosts are designated using the ´ipsec´option in
               shorewall-hosts[3](5).

           ipsec
               Communication with all zone hosts is encrypted. Your kernel and
               iptables must include policy match support.

           firewall
               Designates the firewall itself. You must have exactly one
               ´firewall´ zone. No options are permitted with a ´firewall´
               zone. The name that you enter in the ZONE column will be stored
               in the shell variable $FW which you may use in other
               configuration files to designate the firewall zone.

           bport (or bport4)
               (Shorewall-perl only) The zone is associated with one or more
               ports on a single bridge.

       OPTIONS, IN OPTIONS and OUT OPTIONS - [option[,option]...]
           A comma-separated list of options. With the exception of the mss
           option, these only apply to TYPE ipsec zones.

           reqid=number
               where number is specified using setkey(8) using the
               ´unique:number option for the SPD level.

           spi=<number>
               where number is the SPI of the SA used to encrypt/decrypt
               packets.

           proto=ah|esp|ipcomp
               IPSEC Encapsulation Protocol

           mss=number
               sets the MSS field in TCP packets. If you supply this option,
               you should also set FASTACCEPT=No in shorewall.conf[1](5) to
               insure that both the SYN and SYN,ACK packets have their MSS
               field adjusted.

           mode=transport|tunnel
               IPSEC mode

           tunnel-src=address[/mask]
               only available with mode=tunnel

           tunnel-dst=address[/mask]
               only available with mode=tunnel

           strict
               Means that packets must match all rules.

           next
               Separates rules; can only be used with strict

           The options in the OPTIONS column are applied to both incoming and
           outgoing traffic. The IN OPTIONS are applied to incoming traffic
           (in addition to OPTIONS) and the OUT OPTIONS are applied to
           outgoing traffic.

           If you wish to leave a column empty but need to make an entry in a
           following column, use "-".
