NAME

route_rules - Shorewall6 Routing Rules file

/etc/shorewall6/route_rules

Entries in this file cause traffic to be routed to one of the providers listed in shorewall6-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.
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 Shorewall6-generated 'MARK' rules; 11000-11999
After 'MARK' rules but before Shorewall6-generated rules for
ISP interfaces.; 26000-26999
After ISP interface rules but before 'default' rule.

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

#SOURCE DEST PROVIDER PRIORITY eth1 - ISP1 1000
