SHOREWALL-RTRULES(5)						  [FIXME: manual]					      SHOREWALL-RTRULES(5)

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.

       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.

       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.

       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
