.SH "Description"
.PP
Entries in this file cause traffic to be routed to one of the providers listed in
\m[blue]\fBshorewall\-providers\fR\m[]\&\s-2\u[1]\d\s+2(5)\&.
.PP
The columns in the file are as follows\&.
.PP
\fBSOURCE\fR (Optional) \- {\fB\-\fR|\fIinterface\fR|\fIaddress\fR|\fIinterface\fR:\fIaddress\fR}
.RS 4
An ip
\fIaddress\fR
(network or host) that matches the source IP address in a packet\&. May also be specified as an
\fIinterface\fR
name optionally followed by ":" and an address\&. If the device
\fBlo\fR
is specified, the packet must originate from the firewall itself\&.
.RE
.PP
\fBDEST\fR (Optional) \- {\fB\-\fR|\fIaddress\fR}
.RS 4
An ip address (network or host) that matches the destination IP address in a packet\&.
.sp
If you choose to omit either
\fBSOURCE\fR
or
\fBDEST\fR, place "\-" in that column\&. Note that you may not omit both
\fBSOURCE\fR
and
\fBDEST\fR\&.
.RE
.PP
\fBPROVIDER\fR \- {\fIprovider\-name\fR|\fIprovider\-number\fR|\fBmain\fR}
.RS 4
The provider to route the traffic through\&. May be expressed either as the provider name or the provider number\&. May also be
\fBmain\fR
or 254 for the main routing table\&. This can be used in combination with VPN tunnels, see example 2 below\&.
.RE
.PP
\fBPRIORITY\fR \- \fIpriority\fR
.RS 4
The rule\'s numeric
\fIpriority\fR
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\&.
.PP
1000\-1999
.RS 4
Before Shorewall\-generated \'MARK\' rules
.RE
.PP
11000\-11999
.RS 4
After \'MARK\' rules but before Shorewall\-generated rules for ISP interfaces\&.
.RE
.PP
26000\-26999
.RS 4
After ISP interface rules but before \'default\' rule\&.

.SH "Examples"

Example 1:
.RS 4
You want all traffic coming in on eth1 to be routed to the ISP1 provider\&.

.RE
.PP
Example 2:
.RS 4
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)\&.
