SHOREWALL6-HOSTS(5)						  [FIXME: manual]					       SHOREWALL6-HOSTS(5)

NAME

       hosts - shorewall6 file

SYNOPSIS

       /etc/shorewall6/hosts

DESCRIPTION

       This file is used to define zones in terms of subnets and/or individual IP addresses. Most simple setups don't need to (should not) place
       anything in this file.

       The order of entries in this file is not significant in determining zone composition. Rather, the order that the zones are declared in
       shorewall6-zones[1](5) determines the order in which the records in this file are interpreted.

	   Warning
	   The only time that you need this file is when you have more than one zone connected through a single interface.

	   Warning
	   If you have an entry for a zone and interface in shorewall6-interfaces[2](5) then do not include any entries in this file for that same
	   (zone, interface) pair.

       The columns in the file are as follows (where the column name is followed by a different name in parentheses, the different name is used in
       the alternate specification syntax).

       ZONE - zone-name
	   The name of a zone declared in shorewall6-zones[1](5). You may not list the firewall zone in this column.

       HOST(S) (hosts)- interface:[{[{address-or-range[,address-or-range]...|+ipset}[exclusion]]
	   The name of an interface defined in the shorewall6-interfaces[2](5) file followed by a colon (":") and a comma-separated list whose
	   elements are either:

	    1. The IPv6 address of a host.

	    2. A network in CIDR format.

	    3. An IP address range of the form low.address-high.address. Your kernel and ip6tables must have iprange match support.

	    4. The name of an ipset.

	    5. The word dynamic which makes the zone dynamic in that you can use the shorewall add and shorewall delete commands to change to
	       composition of the zone. This capability was added in Shorewall 4.4.21.

	   You may also exclude certain hosts through use of an exclusion (see shorewall6-exclusion[3](5).

       OPTIONS - [option[,option]...]
	   An optional comma-separated list of options from the following list. The order in which you list the options is not significant but the
	   list must have no embedded white space.

	   blacklist
	       Check packets arriving on this port against the shorewall6-blacklist[4](5) file.

	   ipsec
	       The zone is accessed via a kernel 2.6 ipsec SA. Note that if the zone named in the ZONE column is specified as an IPSEC zone in the
	       shorewall6-zones[1](5) file then you do NOT need to specify the 'ipsec' option here.

	   mss=mss
	       Added in Shorewall 4.5.2. When present, causes the TCP mss for new connections to/from the hosts given in the HOST(S) column to be
	       clamped at the specified mss.

	   routeback
	       shorewall6 should set up the infrastructure to pass packets from this/these address(es) back to themselves. This is necessary if
	       hosts in this group use the services of a transparent proxy that is a member of the group or if DNAT is used to send requests
	       originating from this group to a server in the group.

	   tcpflags
	       Packets arriving from these hosts are checked for certain illegal combinations of TCP flags. Packets found to have such a
	       combination of flags are handled according to the setting of TCP_FLAGS_DISPOSITION after having been logged according to the
	       setting of TCP_FLAGS_LOG_LEVEL.
