10.1.10. More Pipe Examples Chapter 10. Traffic Management VoIP to the remote site is guaranteed 500 kbps of capacity before it is forced to best effort. SAT with Pipes If SAT is being used, for example with a web server or ftp server, that traffic also needs to be forced into pipes or it will escape traffic shaping and ruin the planned quality of service. In addition, server traffic is initiated from the outside so the order of pipes needs to be reversed: the forward pipe is the in-pipe and the return pipe is the out-pipe. A simple solution is to put a "catch-all-inbound" rule at the bottom of the pipe rule. However, the external interface (wan) should be the source interface to avoid putting into pipes traffic that is coming from the inside and going to the external IP address. This last rule will therefore be: Rule Name all-in Forward Pipes in-pipe Return Pipes out-pipe Source Interface wan Source Network all-nets Dest Interface core Dest Network all-nets Selected Service All Prece dence 0 Note: SAT and ARPed IP Addresses If the SAT is from an ARPed IP address, the wan interface needs to be the destination. 505
