############################################################################## # # Shorewall 2.4 -- Internet Service Providers # # /etc/shorewall/providers # # This file is used to define additional routing tables. You will # want to define an additional table if: # # - You have connections to more than one ISP or multiple connections # to the same ISP # # - You run Squid as a transparent proxy on a host other than the # firewall. # # To omit a column, enter "-". # # Columns must be separated by white space and are: # # NAME The provider name. # # NUMBER The provider number -- a number between 1 and 15 # # MARK A FWMARK value used in your /etc/shorewall/tcrules # file to direct packets to this provider. # # DUPLICATE The name of an existing table to duplicate. May be # 'main' or the name of a previous provider. # # INTERFACE The name of the network interface to the provider. # Must be listed in /etc/shorewall/interfaces. # # GATEWAY The IP address of the provider's gateway router. # # You can enter "detect" here and Shorewall will # attempt to detect the gateway automatically. # # OPTIONS A comma-separated list selected from the following: # # track If specified, connections FROM this interface are # to be tracked so that responses may be routed back # out this same interface. # # You want specify 'track' if internet hosts will be # connecting to local servers through this provider. # # balance The providers that have 'default' specified will # get outbound traffic load-balanced among them. By # default, all interfaces with 'balance' specified # will have the same weight (1). You can change the # weight of an interface by specifiying balance= # where is the weight of the route out of # this interface. # # loose Normally, Shorewall adds routing rules to prohibit # firewall marks from working with traffic generated # on the firewall itself. By setting the 'loose' # option, generation of these rules is avoided. # # COPY A comma-separated lists of other interfaces on your # firewall. Only makes sense when DUPLICATE is 'main'. # Only copy routes through INTERFACE and through # interfaces listed here. # # Example: You run squid in your DMZ on IP address 192.168.2.99. Your DMZ # interface is eth2 # # #NAME NUMBER MARK DUPLICATE INTERFACE GATEWAY OPTIONS # Squid 1 1 - eth2 192.168.2.99 - # # Example: # # eth0 connects to ISP 1. The IP address of eth0 is 206.124.146.176 and # the ISP's gateway router has IP address 206.124.146.254. # # eth1 connects to ISP 2. The IP address of eth1 is 130.252.99.27 and the # ISP's gateway router has IP address 130.252.99.254. # # #NAME NUMBER MARK DUPLICATE INTERFACE GATEWAY OPTIONS COPY # ISP1 1 1 main eth0 206.124.146.254 track,balance # ISP2 2 2 main eth1 130.252.99.254 track,balance # # For additional information, see http://shorewall.net/Shorewall_and_Routing.html ############################################################################################## #NAME NUMBER MARK DUPLICATE INTERFACE GATEWAY OPTIONS COPY #LAST LINE -- ADD YOUR ENTRIES ABOVE THIS LINE -- DO NOT REMOVE
