NAME

   rtrules - Shorewall Routing Rules file

SYNOPSIS

   /etc/shorewall/rtrules

DESCRIPTION

   Entries in this file cause traffic to be routed to one of the providers
   listed in shorewall-providers[1](5).

   The columns in the file are as follows.

   SOURCE (Optional) - {-|[&]interface|address|interface:address}
       An ip address (network or host) that matches the source IP address
       in a packet. May also be specified as an interface name optionally
       followed by ":" and an address. If the device lo is specified, the
       packet must originate from the firewall itself.

       Beginning with Shorewall 4.5.0, you may specify &interface in this
       column to indicate that the source is the primary IP address of the
       named interface.

       Beginning with Shorewall 4.6.8, you may specify a comma-separated
       list of addresses in this column.

   DEST (Optional) - {-|address}
       An ip address (network or host) that matches the destination IP
       address in a packet.

       If you choose to omit either SOURCE or DEST, place "-" in that
       column. Note that you may not omit both SOURCE and DEST.

       Beginning with Shorewall 4.6.8, you may specify a comma-separated
       list of addresses in this column.

   PROVIDER - {provider-name|provider-number|main}
       The provider to route the traffic through. May be expressed either
       as the provider name or the provider number. May also be main or
       254 for the main routing table. This can be used in combination
       with VPN tunnels, see example 2 below.

   PRIORITY - priority[!]
       The rule's numeric priority which determines the order in which the
       rules are processed. Rules with equal priority are applied in the
       order in which they appear in the file.

       1000-1999
           Before Shorewall-generated 'MARK' rules

       11000-11999
           After 'MARK' rules but before Shorewall-generated rules for ISP
           interfaces.

       26000-26999
           After ISP interface rules but before 'default' rule.

       Beginning with Shorewall 5.0.2, the priority may be followed
       optionally by an exclaimation mark ("!"). This causes the rule to
       remain in place if the interface is disabled.

   MARK - {-|mark[/mask]}
       Optional -- added in Shorewall 4.4.25. For this rule to be applied
       to a packet, the packet's mark value must match the mark when
       logically anded with the mask. If a mask is not supplied, Shorewall
       supplies a suitable provider mask.

EXAMPLES

   Example 1:
       You want all traffic coming in on eth1 to be routed to the ISP1
       provider.

                   #SOURCE                 DEST            PROVIDER        PRIORITY      MASK
                   eth1                    -               ISP1            1000

   Example 2:
       You use OpenVPN (routed setup /tunX) in combination with multiple
       providers. In this case you have to set up a rule to ensure that
       the OpenVPN traffic is routed back through the tunX interface(s)
       rather than through any of the providers. 10.8.0.0/24 is the subnet
       chosen in your OpenVPN configuration (server 10.8.0.0
       255.255.255.0).

                    #SOURCE                 DEST            PROVIDER        PRIORITY     MASK
                    -                       10.8.0.0/24     main            1000
