shorewall-tcdevices 5 tcdevices Shorewall Traffic Shaping Devices file /etc/shorewall/tcdevices Entries in this file define the bandwidth for interfaces on which you want traffic shaping to be enabled. If you do not plan to use traffic shaping for a device, don't put it in here as it limits the troughput of that device to the limits you set here. The columns in the file are as follows. INTERFACES Name of interface. Each interface may be listed only once in this file. You may NOT specify the name of an alias (e.g., eth0:0) here; see http://www.shorewall.net/FAQ.htm#faq18 You may NOT specify wildcards here, e.g. if you have multiple ppp interfaces, you need to put them all in here! If the device doesn't exist, a warning message will be issued during "shorewall [re]start" and "shorewall refresh" and traffic shaping configuration will be skipped for that device. IN-BANDWIDTH The incoming Bandwidth of that interface. Please note that you are not able to do traffic shaping on incoming traffic, as the traffic is already received before you could do so. But this allows you to define the maximum traffic allowed for this interface in total, if the rate is exceeded, the packets are dropped. You want this mainly if you have a DSL or Cable connection to avoid queuing at your providers side. If you don't want any traffic to be dropped, set this to a value to zero in which case Shorewall will not create an ingress qdisc. Use kbit or kbps(for Kilobytes per second) for speed, and make sure there is NO space between the number and the unit. OUT-BANDWIDTH The outgoing Bandwidth of that interface. This is the maximum speed your connection can handle. It is also the speed you can refer as "full" if you define the tc classes. Outgoing traffic above this rate will be dropped. Use kbit or kbps(for Kilobytes per second) for speed, and make sure there is NO space between the number and the unit. Example 1: Suppose you are using PPP over Ethernet (DSL) and ppp0 is the interface for this. The device has an outgoing bandwidth of 500kbit and an incoming bandwidth of 6000kbit #INTERFACE IN-BANDWIDTH OUT-BANDWIDTH ppp0 6000kbit 500kbit /etc/shorewall/tcdevices http://shorewall.net/traffic_shaping.htm shorewall(8), shorewall-accounting(5), shorewall-actions(5), shorewall-blacklist(5), shorewall-hosts(5), shorewall-interfaces(5), shorewall-ipsec(5), shorewall-maclist(5), shorewall-masq(5), shorewall-nat(5), shorewall-netmap(5), shorewall-params(5), shorewall-policy(5), shorewall-providers(5), shorewall-proxyarp(5), shorewall-route_rules(5), shorewall-routestopped(5), shorewall-rules(5), shorewall.conf(5), shorewall-tcclasses(5), shorewall-tcrules(5), shorewall-tos(5), shorewall-tunnels(5), shorewall-zones(5)
